The shop can be busy, but a busy shop means quality work is being done. Mike reached out to me personally and got my issue resolved. I would definitely recommend his shop and this business. read more

This is an update on the bad warranty, I had work done by Adam and the owner Mike .well I tried to make arrangements to take my car back so they can repair the problem . I only got a email after that no response tried calling but no answer because caller Id . I reported them to the better business. They never got a response from them.so beware taking your high end vehicle to them. They have no accountability! read more

Great shop, I got all my maintenance work done on my E46 M3 with Adam and Mike. Super cool guys and very informative. Will be coming back again! Did my Vanos, Rod Bearings, and valve cover gasket with them. read more

Can't say how much they saved my life with my bmw Cs. I brought in my car in for KW HAS and to do an oil change. The price was reasonable and they finished the same day. Always kept me updated on the progress on my car and gave me their honest opinion on everything. They answered all my questions and made me feel better. The worst part about bring in your car to a new place is how you get treated and if it comes out to your satisfaction. Adam and Kennedy are the best and very honest . Thank you again. read more

I waited a long time to want to write this. This place was cool at first but after doing a big job with them my pure turbos failed, after I got my new turbos they wanted to charge even more in labor the second time around. There was always issues after I put miles on the new mods they installed. It felt like I was coming back every month to change a hose, to check a boost leak, or whatever it was . My car never ran smoothly. They had a way to up charge an say they fixed it. They charged insanely amount of labor. I must of given this shop over 15k in labor. They don't tune themselves either. The tuners they recommend don't know how to do custom tunes. This shop is honestly a disaster if you give them a chance to actually look after your build meaning if you go from start to finish and pay them a lot of money you'll be hurt in the end. It looks like now they partnered with YouTubers and TikTok people to boost their clientele. If you're in Costa Mesa I say check out Raskin Built. He went through my car when I got the new turbos back from pure. The car been running smoother than ever. Precision had damaged the threads on my mounts as well. I had to get them redrilled. At first I would recommend these guys to everyone but they are not the ones anymore! read more

As solid as they come. Great price & integrity with their work, not to mention timeliness, which is key when you only have 1 car.

To my fellow car folks, I purchased a DocRace St kit for my BMW 335is show car. Mike the owner of Precision Dynamics told me the docrace ST kit would be done for Bimmerfest and he would sponsor the install (free install, not ST kit). ST kit delivered on 3/11/2019 finished install on 5/16/2019, albeit a sponsored install. But, I ended up having to pay for the labor cost of one of the techs, as Mike said it was too much and more than he expected to do on it. I paid it no questions asked to support the shop (I did not mention wanting it free like it was promised).   : ensue a mess of headaches from the install: [Preface~ Old turbos burned oil.] They didn't check or replace plugs. Had misfires due to a cracked plug- Was told why would they check these, as it has nothing to do with the install. Coil packs were dry no dielectric grease. -I had to find this out from my tuner and to tell PDM which was blown off like not a big deal. No heat wrap or tape installed under Turbo. -Was told that it is ceramic coated and doesn't make much heat now. Melted passenger airbag line, cracked front bumper due to bag deflating. -found out real fast that the heat comment above was BS, why wouldn't the proper precautions be taken for the lines and what can melt? Melted oil return line from turbo, located hotside -again found out about this going to lunch when someone said hey your car is smoking real bad from the right vent area, pulled over thinking something was on fire. Welp it was the oil return lines butted against the hot side of the turbo housing. Yes it melted and was pouring oil out everywhere. Immediately took it to PDM, to be answered oh its that bad huh? Spent the rest of the day waiting in the shop for it to be sorted out. Loose  bolt on Turbo housing. -after they replaced the oil drain hose which apparently is the wrong hose type. It still leaks oil from something and has a bolt loose. I was at home with a car that leaked 1/5th volume of oil in about 30 miles instead of at Bimmerfest 5/26/2019. There was no response via text or call from Mike during my texts to why it is still leaking oil. The day of bimmerfest no text or call from any of the PDM folks to see where I was or why I was not at Bimmerfest. So I decided to have a second opinion on what is happening. Took it to another well known shop to see if they can diagnose what's happening. They had their master tech look at it, they found a plethora of things that needed to be done correctly. ⁃Coolant hose for expansion tank is routed incorrectly, resting on top of the frame rail (sharp edge). ⁃Oil drain hose that was used was incorrect. Heater hose was used instead of the oil hose. ⁃Turbo was clocked incorrectly. Sitting at an angle rather than being straight up and down as it should be. ⁃Heat turbo blanket was just laying on the turbo, not connected ⁃No heat protection was used on the water pump / thermostat wiring harness which caused wires to melt (not shorted just yet, luckily) ⁃Mac solenoid was installed but not connected ⁃Boost solenoid connectors were laying between the heat shield and the turbo. They would have eventually melted (plastic) ⁃Oil leak from the oil drain line caused oil to get onto other coolant hoses which will weaken the rubber and eventually swell up and possibly fail ⁃Engine mounts were loose (motor mount bolts to subframe were loose) ⁃Exhaust manifold nuts at turbo manifold were not evenly torqued down ⁃Rear turbo oil drain line was cut and was capped with an oversized rubber hose, which was clamped down and beginning to swell. Proper procedure would be to install a freeze plug that is provided with the kit ⁃Wastegates were not completely capped on all unused ports. This would cause the Mac solenoid to be useless because the solenoid would not be able to apply pressure to the wastegate as it is supposed to. For how much talk Mike has done about him being the best n54 master tech in the area, that sure is a lot of issues on a sponsored-ish install. I did get refunded the 600$ I paid toward the install Mike asked for. To make matters even more complex, a few folks at Precision Dynamics have made it known that they do not like me stating my opinion when asked what's up with my car. Apparently according to the professionals over at Precision Dynamics they think I'm a "Fake ass unappreciative ass n****..." These are the folks representing a company who didn't follow through with a completed install and now has cost me money to be uninstalled and then reinstalled. Essentially costing me more than it would if I had gotten it done correctly from the get go without any sponsorship by letting Precision Dynamics install it. I've dealt with another shop up north that did my previous build all wrong. Mike at Precision knew this and told me he would make sure that never happens again as the car is at PDM now. read more

Do not listen to the negative reviews. These guys do quality work. I took my F80 M3 in for down-pipes and exhaust work. John and Mike were extremely honest and the quality of work was superb! I understand they are a new shop, and being a new shop without an established reputation, people will come up with stories and talk shit. Do not listen to the negativity or feed the trolls. I would gladly come back here for any future BMW needs! I have driven 1,000 miles, and it has been over two months since they did my exhaust work; and I have not heard a single rattle or had any issue. Will definitely come back. read more

I highly recommend checking out Mike and Kennedy at Precision. Customer service is on point and genuinely great guys. I had a minor issue with an aftermarket add on and they went above and beyond to resolve it for me. Will definitely be back in the future. Thank you! read more

Great shop to take your BMW to for regular maintenance and upgrades. Mike and Kennedy are very knowledgeable and explained how the cars function in detail. I brought my car here to do bumper conversions, downpipes, and get a tune. They seem pretty booked and busy but always delivered on time as they said. read more

My dad was traveling down to socal in our 2017 Wrx, once my dad was close to making it to LA the car shut down on him, luckily he was able to get the car towed to the shop, and the Kennedy and the team were super helpful with my pops and communicating with me and making my experience less stressful as I was dealing with this situation while being up in the Bay Area, if you guys need work done definitely don't hesitate to go here, great team and great quality can't go wrong with them forsure and can't thank them enough for their hospitality read more

Definitely one of the best shops to take your BMW to in Orange County (same level as all the big name BMW shops like EAS, Auto Talent, etc). My friends and I come here all of the time to get work done on our M cars. Extremely fair pricing and never any issues. Highly recommended! read more

I've had the pleasure to work with Mike and his team and these guys are professional, diligent and true BMW enthusiasts. Mike and team performed a full suspension upgrade inclusive of coilovers, front and rear sway bars, end links, camber plates, M3 front and rear arms, aluminum subframe bushings, toe links, front and rear stoptech pads and rotors, etc. Everything was installed perfectly the first time and I've had no issues with the upgrade despite so many critical components being upgraded. Knick of Eco Luxury also operates out of the facility and he is amazing as well. If you need PPF, auto detailing, vinyl wrap, ceramic coating, wheel/paint repair, he is your guy and is meticulous in his craft. Overall a one stop shop for all your European car needs. These guys are true professionals and have earned my business for life! read more

Precision Dynamics ms - 335is dialed in! - Auto Repair Near Me - Garden grove, California

These guys are amazing!! I took my bmw 4 series in for a check engine light and they quoted me less than half what the dealership quoted me. Turns out the dealship was trying to up sell my parts my car did not even need. Mike was able to diagnose and fix all the issues I had from previously visited shops (one shop blew my electrical unit when installing my dashcam), they even corrected my car tune and replaced my battery since it was blown. They are attentive and very helpful when explaining what the issue is. I have worked with many shops and tried different dealerships, Mike and the rest of the guys here know their cars from A to Z and are by far the best when it comes to taking care of your ride. Would highly recommend! read more

Hands down the best shop I've been to. Highly recommend! Everything from start to finish. Keep up the great work! Definitely will be my go to place for all my future work! Thank you! read more

Precision Dynamics ms - Auto Repair Near Me - Garden grove, California

-unprofessional -lack of communication -poor work Back in December 2018 I had an oil pan gasket replacement. They damaged my hood on the process and was not notified of the damage at all. I was out of town for a week so I had my sister pick up the car. Anyways, I send him a picture of my hood and he acts like he doesn't know what and how it happened but then tells me exactly how "it could have happened" lol. Several messages go back and forth and we finally come to the conclusion that he will fix it. A month goes by and he has an unfortunate event. At the time I didn't want to hug him since he was going through a hard time. We ended up agreeing to him just giving me a carbon fiber steering wheel($4-500 value) sometime in January/Feb. It's JUNE 2019 and I still haven't received shit. Poor communication from Truong and John. I honestly don't care about the wheel anymore. I ended up replacing my hood with my own money. Stay away from this shop. I have A LOT more screen shots of all our messages. read more

Sadly had play follow up with them many times. Not once but 2 times and never got back to me on questions and quote. Customer service is very sad. It should not take 2-3 weeks return a reply if so tell the customer it'll take that long. If you can't even do the basic of customer service.. how can I trust or allow you you do even basic services on my car. read more

I was actually recommended here due to the nature of my car and situation....Don't waste your time calling. They have no interest in helping you out. Their reputation is more important then the actual services the supposedly provide. Yet another BS shop in Oc. read more

Now that I look back, I feel dumb for continuously coming back to this shop, which ended up costing me $7-10k. So many false diagnostics to just replace some parts that possibly weren't even at fault. As another mechanic called them "part replacers", I couldn't help but laugh. All these reviews that speak about getting left on read, or not getting updates are spot on. After many many visits, the last time I was at the shop, Mike sent out one of his mechanics to speak to me to avoid confrontation. Drama shop, just stay away. read more

STAY FAR AWAY FROM THIS PLACE I've heard lots of stories from ppl in the BMW community about shady things that this shop has done. I personally had a clutch installed by jon (one of the mechanics). The clutch didn't feel right and was making a grinding sound. Jon said to bring it in and if it turns out to be defective he would take care of me. Turned out to be defective and replaced a second time, I was charged for labor twice and twice for the clutch but only refunded for 1 clutch which leaves both labor still out of my pocket after I recieved messages from jon saying "I'm trying to make this right, and get you to stop talking shit about my work ethic. I could care less about taking a few bucks from you. Or messing up your car." The lie detector determined that was a lie read more

Came by to check out this shop. Very rude some guy name Kenndy was not friendly. Felt very unwelcome. Definitely won't come here again. Not very good customer service. I just wanted to ask some questions for my car. They said you need to stay out. I understand that they need to that for insurance reason. So they put a chain up. And walk away. Not asking if I wanted any help or information. Very bum in how they treat potential customer read more

Alright, I've been meaning to leave this review but then forget, and then remember again every time I jump in my beautiful car and drive it haha. Let's start by saying that Mike, Kennedy, Marc, and the whole PDM crew is the best in the West. I drive a regular BMW 328i (nothing fancy I know) but took into the fellas for servicing/parts and boyyy I gotta tell you... every time I drive off with a smile on my face and loving my car even more. This is my first BMW and I love it even more thanks to these guys. If you own a BMW, AUDI, or Benz I highly recommend you check this place out. Mike & Kennedy thanks for the amazing service. Cheers! read more

I took my M4 to Precision Dynamics for a valve cover replacement, and all I can say is that they hooked it up even though we had a little misunderstanding, Mike hooked it up and handled the situation professionally and kept me posted with the install process. However, Mike did the install without charging me, and that shows how they care about their customers. These guys use legit OEM parts, and I will definitely bring my car here if I needed a repair done. read more

Had a stellar experience with this shop. Everyone knows what they're doing and very efficient. My biggest pet peeve with a shop is over promising and under delivering. These guys hit the nail on the head when it came to doing what they said they'd do. More than willing to come back for more work. I now found out there isn't a thing you can't do here. They're are the true one-stop-shop. read more

I dont usually write reviews, but I definitely gotta recommend anyone who needs custom work done. No joke, these guys are very good.

Very knowledgeable. Dont let the shop fool you. read more

Be careful of this company. I went here to perform some basic services such as replacing a valve cover gaskets and an oil change. They charged me for the services but found out later they never actually performed the services. Before dropping my car off, I put in indicators that would show if they removed the parts off and I noticed nothing changed/moved. I'm not sure if they have changed since then but be aware of these guys. At the end of the day, they are salespeople. read more

Be careful with who you trust your vehicle with! Poor work quality, and even worse customer service. Overall bad experience . This shop is known for scamming people and being complete liars. There reviews are from friends and employees, not actual customers. I have saved over 25 screenshots of issues with "mike" aka Truong. IM HOPING HE RESPONDS SO I CAN PUBLISH EVERY SCREENSHOT ON HERE! Bring to light the garbage he calls a shop. How can you screw over the people who put food on your table week after week??? read more

Picked up a catless downpipe for my F30 and I did not trust myself installing it. Glad I brought it into Precision Dynamics. Had John installed my downpipe and he discovered that the bolts that clamped down the downpipe was bent out of place and it was literally stuck on there. John figured it out and swapped out the downpipes in no time. Glad I brought it in because I don't know how I'd go about removing those clamps with the car on jacks. I was in and out in about 45 minutes or so. These guys are definitely my go to guys! read more

I've had over $12k of work done here. They are extremely busy and if you are a tuner buddy they seem to treat you better. If you don't have an inside connection, be prepared to wait and wait. Also very little feedback and customer service. Had to follow up multiple times for simple items. Not much explanation of where things are and how long it will take. I understand that some of the delay was caused by parts on order being delayed but waited more than 4 months to get things done. I have 7 cars and had work done by numerous different auto service shops for different brands. IMHO this shop does not pay attention to details. I had to closely keep track of job not done so that they would get done right. The verdict on the quality of work is still out. I've had some minor issues which seems to have been resolved. We shall see after some operation of the car. Requires a lot of follow up. Not a high quality shop. read more
