Once again another great service. I have a 2011 Turbo, not some new high end race car, more an everyday driver. Alan and his team just finished an oil service, brake fluid flush and replaced the tire pressure monitors that were simply too old to function. They did this professionally, quickly and with great care. These guys are the real deal, I don't get how anyone could be disappointed with the service, care, honesty or cost. So much better than the local dealer. Do yourself a favor and call GMG first read more

Super stoked to have had the pleasure of these guys working on my 2019 White GT3 RS. I wanted the car ready for Top Track weekends. Had them dial the suspension to make the tricks around the track work. No messing around and money is not an option when it comes to making it right. Titanium exhaust which sounds glorious and makes the haters mad. Love the car and I cant wait to hit the streets where it belongs. read more

Sent my Ferrari 458 Speciale for a tune. I love the end result. I dealt with Alan Ward. He was very knowledgeable, friendly, and maintained great communication. I loved the car before, but now it's even better. I will never sell it. GMG is fantastic, and i made a friend! read more

owner is shady and never responds. No refunds. No warranty. WAY Overpriced. One guy works there doing everything.

This place is ridiculously bad they damaged the wheel while I left the car for them to finish a PPI and while they test drive the car they scratched the rim. read more

Recently bought a set of seats for my car with 6-point subhole upholstered custom by GMG Racing's offering. Very happy with the end result! Especially want to give a shoutout to Allen for working with me through the tricky process & following up at all instances! Will definitely work with them again! read more

Bad experience with quality, customer service, and software compatibility with other modifications other then theirs. Headers cracked twice with about 15k miles of use. They rusted very easily. Also, had to switch to Cobb tune after GMG was unable to fix limp mode after adding intercooleres, plenum, and y pipe. 991 Turbo S headers over 5k to last 15k miles is garbage. Stay away from this brand. Once they take your money they will not help with problems or stand by the quality of their products. All of their products are without warranty. Cash preferred at this location looks very shady on their part. Typical over ppromise under deliver business practices. Half star here. To be continued on forums and social media. read more

A great shop for Porsche service,roll bars,exhaust etc and race car set-up.and this stupid app is asking me to type more

Highly recommend these guys for any service/aftermarket needs you may have for Audi's or Porsche's. The knowledge all of the techs and managers have makes just one visit so informative. Customer service is truly the best from any automotive shop I've experienced and I can't say enough good things about GMG. I'll definitely be a repeat customer! read more

Professional service, using State-of-the-Art resources and technical superiority that cannot be matched. Thanks, Allen and Alex! read more

I won a free alignment job gift certificate from SoCal euro fest and tried to redeem it but you have to purchase suspension components that are 1k+. Not a very good offer. They might as well give everyone a gift certificate for alignment jobs since the catch is a must purchase component.....the components range from 500+ I did not win anything. Worst raffle prize ever. read more

The A-team! I've been looking for a dependable, knowledgeable and a professional shop to help me with my Shelby GT500 performance upgrade for some time now and I have finally found what I've been looking for. I tried different outfits but they often came short of the expertise to do the job right. This place does a lot of work on European sports cars but they have range when it comes to different make and models. Eric who worked on my car was actually more knowledgeable than ford and shelby in Vegas who pretty much never even returned my phone call seeking help and expertise. Shelby in Vegas was most disappointing considering my repeated calls to them went unanswered. They feel entitled and above it all. Shelby just does expensive packages for upgrades and anything in between doesn't get their attention or time. Eric's work on my car was pretty extensive and extremely professional. I'm happy to have found Eric and the GMG Folks specially since they're in Orange County close to where I live and look forward to working with them in the future to start my second phase of performance upgrade.

This place is fantastic. I really like the atmosphere. But don't waste your time if Joe will help you. Very bad customer service from this guy. But I still recommend this place. read more

I have a 2017 Volkswagen GTI and called 3 separate times to ask about a couple APR parts (APR Short Shifter and Stage 1 tune). The first and second time I called the team was busy with customers, so they took down my phone number/name and insured me that I would hear back from them that day...never did. The third time I got transferred twice after saying what car I have and then hung up on after being put on hold for several minutes. I can't comment on the quality of their car work since I was never able to actually get work done on my car, but their customer service is terrible! If you don't service the same cars as stated on APR's website you should NOT be an APR dealer. read more

Looking for a Tuner for my 458 Speciale. I put an exhaust on on the car and it triggers a code..... If you are reading this you probably already know the story..... So..... I'm OCD.. i searched and researched and searched, bla bla bla.... Let's just say I do my homework before choosing a place. I talked to many tuners. Mostly all had good to great reviews and ratings. I finally called GMG and spoke to Allen... It didn't take more than 2 minutes to recognize he really knows Ferrari. He was extremely personable, and willing to help out, even b4 knowing he had my business. I live in MA! Allen really put my mind at ease that I was sending my car to the right place. Can't wait! read more

I would like to thank ALLEN for helping me with my Bentley. I got quote from other place with a full page of issues and service price was outrageous. I am so glad I find this place. For a girl, I knew other place tried to pull a fast one on me before knowing Allen. Allen is extremely knowledgeable, respectfully, kind, and very honest person. The moment I talk to him I knew that this shop is trustworthy. I can't thank Allen enough for providing excellent service on my car at a lowest price compares to other places. I strongly recommend this shop. Many thanks Allen. read more

You can't help but feel good leaving the GMG garage! I wanted a little more kick from my A6 and that's what I got; added a boatload of power. I can't say enough about Allen, he is thorough and honest. I loved the tour of the garage! Thanks again! read more

Called Porsche Irvine, and Circle Porsche- Where I bought the car(live walking distance to the Death Star, Autonation Newport Porsche-horrible), neither could help or, really, knew anything. Scotty at GMG was knowledgeable , and genuinely cared about my situation. He had me take pictures and e-mail him, he responded immediately. They worked on my Turbo, I didn't know they took care of "regular" cars also. Will uldate after my service. read more

Went in for a quote on GIAC tune and Milltek exhaust, never heard back.. Called to see if they "lost" my information and said they would get back to me.. Still nothing. These guys only deal with high-end cars.. Don't waste your time going if your car cost less than $80k. Good luck with racing, still a fan! read more

I was looking to improve the sound of my 911 turbo, so upon reading GMG product description of its performance exhaust it sounded like the perfect solution, describing the sound as reminiscent of the Carrera GT with out the drone of many sports exhaust, As i drove the car home I realized I might have made the wrong choice, I gave it about two more days and then called to arrange to return the car to stock, thats when my disappointment was fully realized, neither James Safronas nor his business partner would address the misleading advertising and basically avoided my calls for weeks refusing to refund just 50% of the $5,500.00 cost I had asked for. ( I own a business and understand they have restocking fees and other costs) Finally I made the decision to just let it go and not spend any more time or money to try to teach them a lesson. I have owned ferraris, Aston martins, ford GT ect and understand that acoustical engineering is necessary to build a proper sounding exhaust system, ( I have a quicksilver system on my Aston and its phonominal) What GMG does is simply make finely constructed big tubes that sound like any droning cheap japanese import with an after market coffee can sized pipe. For those who don't care about an acoustically engineered sound, GMG's system does increase throttle response and probably HP but I am skeptical to the extent they advertise. Biggest disappointment however was how the Owners handled the situation once they had my money. Never again GMG, I recommend their competitor ,TRG who have already won more races than GMG will ever win in their lifetimes. read more

Good guys. I used Fabryce and the crew at GMG multiple times to work on my 996tt. They did my clutch, my suspension setup and trans rebuild. It helps that they're only a mile from my shop. But the service is always professional and it's done when they say it will be done. That means a lot to me. And as a bonus it's always nice to see the FCars and other exotics when you stop in. read more

If you own a sports car and it happens to be a Porsche then this is the place to go. I would ask for Allen. He is extremely knowledgeable. Great customer service skills. The prices are very fair and are better than taking it to the dealer. This place gets my highest endorsement. read more

I have used GMG for standard service and performance modifications on my Porsche 911S for several years and have never been disappointed. Most recently, and for the first time, my car broke down with an unknown problem. GMG diagnosed a wire connection issue between my control unit and throttle body and the car was ready the same day. There were no computer codes that helped diagnose the problem. GMG also installed a light-weight flywheel, sport clutch, sway bars and radiator grills. I use them for standard service too. read more

Brought in my e46 m3 for a PCA track day inspection. Alan gave me great detail of my setup and what could be done to improve lap times. You can tell they have racing experience and know what they're doing. I would not hesitate to take my car in for service and dialing it in for the track. read more

I have been searching for a good place to modify and service my car and I'm really happy that I stopped by to GMG today. The technician took really nice care of my car and he was fast and accurate. I really appreciate for his hard work. Either you call in the shop or stop by to the shop, you should look for Scott, the general manager. Before I actually met him today, I bothered him a lot through email but he didn't mind and answered all my questions right away. Today when I met him, I found out that he was very kind and attentive gentleman. He helped me from the beginning until the end. He made a smooth procedure throughout my experience at GMG. I'm also a huge fan of Mr.Sofronas, the owner. I was hoping to meet him today and when I actually met him I was extremely surprised that I became speechless. He also let me take a picture with him. What more can I say. It was such an honorable day for me. I am so glad that I got my car serviced here and I will definitely keep coming back. I can say today was my birthday. I really appreciate for GMG's professionalism and hospitality. Thank you everyone. I highly recommend this place. read more

This shop is great, I have used them for standard service and they are very helpful and knowledgable when it comes to all European cars. I would highly recommend taking any vehicle especially if you are looking to do a basic service (if your car is out of dealer warranty). read more

Honestly one of the best customer service provided by Global Motorsport. Greg the owner such a nice, humble, and caring person. He makes sure his customers saves money, and gets the best deal! read more

No stars off for me. First place for GMG in my book I own a european exotic and found their prices more than reasonable given the quality and professionalism. Yeah, it costs more than Jiffy Lube but if you're like me then you're very particular about who works on your car. GMG more than passed the test. The shop is clean and extremely well-equipped. The techs and managers were competent, helpful and straightforward. If you appreciate european performance then you'll value this very impressive shop. read more

Brought my 997 RS here a few times but have settled on another shop. There is just a little too much attitude here and a couple of the jobs they did weren't quite up to par for me. Attention to detail on service seems a bit lacking. Example, had new cup rotors installed and they were installed opposite l/r to how they should have been which makes cooling a little bit of a problem. That said if you are paying them for full race and track support they seem to do well and cars are very competitive. That seems to be more their focus with the other jobs they do helping to support the race habit. read more

I've been bringing my FCar to Alan when he was at Autosport International and followed him here. Great service, reasonable rates for exotic car services. Would highly recommend for anyone looking for an independent service provider for your exotic car. read more

Excellent experience with a fairly comprehensive install of both suspension and power parts. The install was both timely and perfect. They are good people! read more

Awesome place! Scott Centra showed me around and I was blown away by the cars they had and the cleanliness of the facility. They also have a race team. I will definitely bring my next Porsche to these guys. They did a great job with my 996 Twin turbo when I had an ECU problem. They really know what they are doing and so does Scott. read more
