HG is a great resource for track oriented alignments on many brands including Porsche. They aligned my Boxster suspension to my specs and did an excellent job offering suggested improvements along the way. Many mechanics at HG are enthusiasts themselves, so are quite adept in setting up their own cars for the track or racing. read more

Knowledgeable, reliable, punctual and detail oriented this is the place to go to. Whether you are modifying you Porsche GT3 RS or keeping you old Mercedes on the road the team here knows how to get it done. We bring our old E320 cars here along with our turbo s and even our little smart car. Whatever I throw at em, they handle it. They won't take you to the cleaners either. Also it's fun to see so many exotic cars every time I swing by This is a happy place. read more

I'm soo happy and thankful that i took my e93 M3 to HG performance. Vin and Devon were great! they were 100% transparent about pricing and also provided progress of the the work they did. The finals results turned out great, my lip that i purchased didnt have the most perfect fitment, it had a bit of a gap but it was mainly the lip manufacturer not doing quality assurance. HG made it work and it there was very minimal gaps for my GT4 style lip with air ducts to my brakes. I would highly recommend this shop for all of your Car modification needs / services. Attached is the final product after the installation read more

Great experience as always with HG, going above and beyond in making sure everything is just right. Last month helped with an annual maintenance on Maserati Quattroporte, and this week upgrading some fogs/light bars/oil service/sunroof fix on a Ford Raptor. Thanks to Omar and team! read more

Best place in Southern California to fix up, upgrade or customize your high end automobiles! Amazingly knowledgeable staff with experience and great customer service. When it comes to obtaining a mechanic these are my top three priorities and they top the charts for all three. It's a bit of a drive from my house but piece of mind is worth the travel. I'm extremely happy with this location and will be back again soon for the black out package. read more

Outstanding service and a great price for a pre purchase inspection of my C7. Soon they will be "fixing it" by adding a pro charger and intercooler. Thank you VIN for always looking out for your customers. read more

I took my modified 96 M Edition Miata in today for an alignment and I specifically asked for my buddy Chase cuz he has a highly modified Miata also and his is track oriented and he knows how to dial in the suspension to a T...he drove it and then aligned it and then he did this procedure at least 5 times over a 2 plus hour time period before handing me back my keys. I had just installed Feal 441 coilovers and I broke them in and it was ready to be dialed in and he nailed it. $250 might seem a bit $ to some but tbh with that many on and off the rack adjustments on a highly modified car is literally a steal thus he actually hooked me up and made time for me during a time when they have some very big jobs going on right now...thank you very much for fitting me in your tight schedule...I'm very appreciative..., Michael read more

HG Motorsports is a game-changer! I went to them for a second opinion on my Nissan GTR Nismo after another mechanic said I needed to replace my turbos, costing over $40,000. The team at HG Motorsports took a look and assured me everything was fine, saving me a ton of money and stress. The service was fire, and they worked around my schedule. Special shoutout to Chopra, who made the whole experience smooth and easy with clear communication and helpfulness. HG Motorsports specializes in luxury and exotic cars, making them the go-to place for high-end vehicle owners in San Diego. Highly recommend them for great service and honest advice! go check them out and tell em Mike Barron sent you. See you at the top! -Mike read more

A hug thank you to Devin, Omar, and the team at HG Performance! My R34 Skyline was down and out shortly after taking delivery of it from port. A blown fuse was the culprit, and Devin had me up and running in no time! They did a thorough diagnostic of the whole car and informed me of issues to be aware of, if they come up. They are knowledgeable of all the Skylines; there were R32's, R33's, R34's, and R35's at the shop. I'm happy to have found my home base to take my modified R34! read more

Omar Mehr! Beyond amazing! I've known omar since 2012 since hg performance was located in LA jolla to then move to Sorrento Valley then to San Marcos Hg Performance has always taken great care of me and i highly rate this mechanic shop! They take very good care of their customers including myself! I reached out to Omar about some apex wheels arc 8 flow forged rims and he got back to me so quickly and gave me a great deal! I purchased them on the spot for my 2011 bmw 335i e90 m-sport. Hg and Omar has always been their for me when I need a hand, from the day I had my 2002 bmw m3 to more than 12 years later helping me out again! The team at hg performance is top notch! Please reach out to them for all your needs from a Honda civic to lamborghini or ferrari or full track build they got you! read more

Great place to get work done on your car, whether it's general maintenance or performance installation. This is the only place I trust with my Toyota Supra. The team here is always knowledgeable and transparent and they'll get the work done right the first time at a fair price. read more

Top notch work and extremely professional. These guys know what they are doing. They have worked on My porsche, VW touareg and my Alfa Romeo Giulia Quadrifoglio! I don't let anyone work on my cars but I trust these guys! If you have an Alfa Romeo (modern) this is the only shop for you!! read more

As usual, excellent experience. I needed to get a new tire installed and since I have custom Wheels I would only trust them to do any mount, balance, or alignment. They have ALL "performance" quality equipment and staff are highly knowledgeable with many various applications. The level of Service is great and go above and beyond to drive the overall Customer Experience. Highly recommend them to anyone and are the premier shop in SD County- Thanks guys! read more

I just went to hg as a walk-in to get a coolant leak diagnosis for my car. They said to diagnosis, it shouldnt take more than two hours. They went above and beyond to fit me in tomorrow since my current mechanic is out sick. If my mechanic is unable to service my car I will definitely go back. read more

I was one the original customers when Dieter owned it. I used to go Heinz Geitz in La Jolla, then when Dieter started HG performance I stayed with him. Since he sold it the service has fallen quite a bit. I know a lot of people are leaving good reviews,(probably because good service in general is hard to come by now a days with this younger generation)but I cannot since I know how it used to be. And they after the big bucks , not interested in smaller jobs. read more

Awesome customer service! Came in to get the brakes and rotors replaced on my M3. They did a great job, No complaints. I will definitely be coming back for future repairs down the line. Side note if you're car is lowered: they have a steep entrance so beware of that. read more

HG Performance is simply amazing. I've had my Nissan Altima since she was 7 miles old. Since then, she's grown quite a bit. And so has her service bill. When her check engine light came on at 112000 miles, I took her to the dealer. They told me it'll cost both my kidneys and 3/4 of my net worth to fix. I responded with two middle fingers and flintstoned my way to HG Performance. David was my technician. He gave my baby a complete mommy make over. That's right, he's like the anti-aging pill for cars. But better. His medicine was a new transmission and intake manifold. Now she drives like she's 50,000 miles younger. I'm so grateful. Her and I are going to hit the road and drive through this journey called life again. I'm grateful that HG took care of her so she can take care of me. I'm checking out now, as I have some driving to do. Final remarks: I highly recommend HG Performance. read more

I took my 2009 Mercedes C300 here for an issue that could not be resolved at 3 other workshops over the course of a year. The team at HG Performance solved my issue the same day that I brought the vehicle in. I wish I had known about this place sooner. As long as I have been bringing my car to a mechanic, I have not met someone both so dedicated and equipped to diagnose and fix problems as was Phil. He clearly was an expert in what he was doing, and there is no reason to take your vehicle anywhere else other than HG Performance. read more

Don't waste any time and money on the other shop! I'm tired of getting messed over with different shops... Go to HG performance! I went to different shops and I ended going here, trice! I tried to work it out with other shop and I ended up paying more and wasted my time. And still didn't fix my car! Very stressful... HG performance will take good care of you. They're very honest and they will guarantee their work! I'm writing this review so you don't have to worry about anything. Lesson learned! Don't be like me... Highly recommended! Appreciate all the help! GOD bless you guys! Keep up the good work read more

What an amazing shop!! I had read the reviews by other Yelpers and knew HG Performance was golden. I recently purchased a car from Texas and wanted an overall inspection for piece of mind. From the first contact with Neema, all the way to signing the receipt, he was outstanding. He explained the history of the vehicle's make, giving me excellent information. Neema is very easy going and you can tell he cares about his customers and their cars. The service was excellent and of the highest quality. Neema explained what was covered during the inspection (pretty much everything) and gave me a thumbs up on the condition of the vehicle. This gave me such piece of mind!!! Thank you Neema and team for your excellent work and showing your customers you care. HG Performance will be our new go to shop and should be yours too!!! read more

Had HG install Eibach springs and 18MM spacers on my Model Y. Their communication and service were top notch. They kept me in the loop and I am extremely pleased with the finished product. I cannot speak to price as I did not shop for the best deal, I shopped based on feedback and these guys lived up to the 5 star rating. Thank you, Jeff read more

I was lucky enough to find a 2005 E55 AMG wagon with a 113K on it a couple of years ago, and on the recommendation of a friend (who trades mostly high-end / exotic autos) took it into HGP for a thorough going over and in particular to replace the tired suspension bushings and shot motor and tranny mounts, and do a full alignment, etc. ,etc. I'd read up quite a bit on these cars on the tech forums for a few years before owning one, so had some insights as to the car's tech attributes and issues. During the work, I had a few chats with Neema and mechanics there and it was really a pleasure to find out these guys actually KNOW and love these cars, plus have all the factory shop gear (STAR and so on) to diagnose and sort them. I put several $thousand into this refresh endeavor, and was very pleased with the results. Had a module go out (right turn signal et al)... they effected a speedy solid fix that didn't break the bank... A few months later, a serious tire wear issue revealed itself to me, so I called Neema, brought it in and again they had the cause diagnosed and fixed in short order. HGP aren't going to be the lowest price but their professionalism, knowledge, enthusiasm and quality of work here is genuinely top-notch. I'll just add that I won't be using the dealer for anything but recalls (and occasionally parts when I do work myself). Judging by the range of high-end performance vehicles on their lot, stock and modded, seems I'm not the only one who trusts these guys. IME, their great Yelp is well deserved! read more

I unfortunately scraped the back right wheel of my car and had a bad case of curb rash. Omar and the team at HG Performance came to the rescue and matched the powder coating on my wheel and made it brand new in 4 days time! Thank you for the impeccable service and rapid turnaround! read more

Wasted my time , ignored my emails trying to setup an appointment. Truly unprofessional

This car was the first nice thing I've purchased for myself in over 10 years. Shortly after purchasing it, I experienced major mechanical failure. I had another shop in Texas attempt to rectify the situation for me. They didn't. I was gaslit for over eight months and when I received my car back, it was performing worse than when I purchased it. I took it to HG and was given top-tier treatment. The issues were not simple, it took multiple diagnostic tests and OMAR, Devon, and the head mechanic, took it upon themselves to make sure to cover every single base until my car was back in perfect condition. I could not be happier. I'm very appreciative of this entire team. Professional, courteous, communicative. I can't think you guys enough. I can finally enjoy this car the way that I always wanted to. You all are truly professional in every respect. Thank you from the bottom of my heart. I recommend these guys to anybody, with any type of vehicle, with any type of problem. They will take great care of you. read more

I want to say HG Performance is my new go to shop for any service on my bmw. I had a stage 1 tune performed by VIN and he was very knowledgeable and pleasant to work with. Car runs great now. Devin was also very knowledgeable and pleasant. Both of you guys are a nice change from other shops. Thank you Chad read more

I've taken two cars to HG Performance: one for an engine tune to get more power (VW) and another one for an install of a new grill (Audi). These guys are great. Very professional and it's clear they know what they are doing. I'm a novice to anything aftermarket and I feel very comfortable trusting them with my cars. Now go do something cool to your car )or your wife's car).... read more

Best shop for all your automotive needs. Highly recommend if you want quality workmanship. From scheduled maintenance to handling hi performance upgrades and tuning. If you love going to the track, HG is your go to shop. read more

Wow!! HG performance was a such an amazing experience. It was nice to meet guys that are extremely knowledgeable and enthusiastic about what they do for work. I had a great experience here and can't wait to have more work done. I've already recommended HG to several friends. You won't find shops like this around as I've been to a few. read more

These guys were highly recommended to me from a very trusted car friend here in SD. I started talking to Daniel about tuning my Evo and he told me everthing i wanted to know. i let him know everything i had on and for the car... He gave me an over the phone quote and a appointment. the day i walked into the shop Daniel gave me a tour of the whole shop and man was i impressed lots of top end cars so it made me feel good about leaving my Evo. So i dropped it off. The next as planned i got a call from Daniel and was told my car would be done on time and cheaper then what he quoted me for. Picked up my car and Daniel asked if i had any questions, i said how much power gain?? he told me almost 100hp!! So i leave and right away i could feel a huge difference! i talked to him later and everything was great! he sent me the Dyno printout and we were done. Great experience from the beginning to the end even to today! (i'm a little late writng this like a year!!) Will definitely go back to these guys and i highly recommend going here for all your auto needs!! read more

They took amazing care of my car and I went I. To get my new steering wheel installed and didn't take to long at all.

Will be coming here more Often for work needed! read more

Excellent service! I took my Tesla Model 3 into HG Performance for a suspension upgrade after finding them on online forums and being recommended by Mountain Pass Performance. I was taken care of from start to finish by Neema and Phil, where they patiently answered any questions that I had. The technicians were also professional and you could tell they cared for the cars they service. HG installed for me new MPP coilovers, rear camber arms, and solid front lower control arm bushings. My car has completely transformed and I absolutely love the feel of the drive now. These guys rock and will take care of you, check them out! read more

Took my Alfa Romeo 4C to HG to perform the timing belt service. The largest service item on these cars and it is difficult to find a shop that has experience with the job and will do the work. AR dealerships in the area are difficult, expensive, and don't seem to actually know much about the 4C. Really impressed with Phil and the HG team on their cost and turnaround time of doing my timing/accessory belts and water pump replacement. Cheaper, faster, and more knowledgeable than any Alfa dealer experience that I've had. Phil was always updating me on where things were at and what they were doing. Really great experience overall and I would highly recommend them. read more

An outstanding experience. They came highly recommended from several car enthusiasts in the area and I could not entrust my new C8 Corvette to anyone but the best. Neema is very professional, knowledgeable and will take the time necessary to explain exactly what your options are with the pros and cons for each. I am extremely pleased with the look and feel of the suspension work they did for me. read more

First off Neema provides the best customer service you'll ever find. He's knowledgeable and very thorough when it comes to researching and explaining the service on your vehicle. With their new location I find that bringing my fiance's GT-R to get serviced there is well worth the drive. In the past we had Alain install the alpha kit on our GT-R. He went above and beyond when he installed it! My fiance is very picky when it comes to fitment, symmetry and alignment! After the parts were installed the car was perfect! Alain's work was pristine! Never had any issues with the car after the install. The only problem my fiance has is keeping the gas tank filled. The mechanics here are more than knowledgeable and reliable when it comes to working on high end vehicles. We go here for something as simple as an oil change to something complex as installing high performance parts. The turn over time was impressive! My fellow gtr owners were impressed at how fast the build was done and at that level of quality. Give them a try if you're new and you'll be impressed! This is one of the few shops that treats you with care and most importantly, is honest! read more

I've been coming here for aftermarket performance upgrades for my BMW and they do a fantastic job every single time I've taken my car here. They treat my vehicle like their own and the whole team treats me like family. Experience and enthusiasm working on high performance vehicles is their forte, I wouldn't go anywhere else. read more
