Gruppe-S Engineering

Best prices and Eddie knows his stuff about cars, he’s been in business for 20 plus years. Dynamic Autosport rocks!!!

During my early years of my life long passion with cars, there was this one local shop that stood out in particular, Dynamic Autosports aka Gruppe-​S Engineering. They supported local auto enthusiasts and everyone always had great things to say about their service. I even was a walk in customer for some Motul brake fluid many years ago when I needed some in a pinch.
Unfortunately I am walking away from this place and avoiding recommending this place to any fellow auto enthusiasts. My last dealing with what turned out to be the long time owner of the company, Eddie K., was a tragic disappointment and let down.
Our transaction started a little something like this:
1. I posted on a facebook group that I was looking for a particular part.
2. Among the people to contact me for pricing was Eddie.
3. Knowing Gruppe-​S Engineering’s background and my previous dealing with them, I figured I was in good hands.
4. Eddie quoted an awesome price so I put down a 50% deposit via paypal gift (I know I know … I shouldn’t have but I’m cheap and didn’t want to pay the fee plus I trusted him)
5. Few weeks later, half of the promised parts show up at my front door = awesome
6. Another few weeks later, nothing.
7. I messaged him to let him know that I heard the latter part I wanted was discontinued. He confirms this indeed true. So I let him know lets cancel the other part and just refund me the difference and I’ll chalk it up to bad luck. He says sure.
8. Few weeks rolls by, no refund, no messages.
9. I message Eddie again and he tells me to hang on some more because he’s still working with the vendor to get a refund and then he can refund me.
10. Another few weeks goes by and nothing.
11. Another few back and forth of «give me another week», same story.
12. In the end, he stopped replying.
So that was that. I did get half of my promised order. It was higher than originally quoted since he didn’t refund me the difference. I still walked away with a decent price for a part albeit not a good deal as promised. All in all I took this as a lesson to not trust anyone with a paypal gift payment unless it was my mom. In the end, it was all about ethics and communication. I didn’t get scammed or robbed. But I felt like I was betrayed and lied to. Therefore, I can no longer recommend anyone to them as I previously did.

This fine establishment has provided me the best deals on some high quality parts (TEIN coilovers and Weds wheels). I bought the coilovers on 02÷09÷15 and the wheels on 02÷24÷15. Eddie is extremely responsive and will take care of you. If you are an active online shopper, you will see his deals pop up at various websites and forums. I am definitely looking forward to doing more business with them in the future.

I needed a new set of wheels in a hurry after an accident. I tried to contact Gruppe-​s 8 times in a 3 day timespan, all during working hours on a weekday. They didnt answer one time, and couldnt bother returning my messages.
Any business that is this bad at customer service — that cant even answer the phone deserves 1 star.

Knowledgeable staff, great prices, great service. Really not much more you can ask for from a automotive enthusiast shop.

What can I say? Honest service, best prices, I’ve used them to install suspension kits, wheels and would trust them with anything. I’ve been coming here since they were located in the irvine auto center which was about 20 years ago? I’ve had them work on my DB8 for everything and would use them again in a heartbeat for my next ride. They’ve been around forever, and I’ve always been happy to utilize their services.

Was recently in dire need from some new coilovers because the ones I purchased a lifetime ago (coincidentally from Dynamic Autosports as well) were way beyond their years and need to be replaced. With the help of the extremely knowledgeable and friendly staff, Nam and Ed, I purchased the KW Variant 3s. Which were a great buy, considering the performance and OEM like ride you get. The price was the best I could find anywhere and the service was great.
Cliff Notes:
Great people, great products, great service.
Would I go back?
Yup. I have and always do when I need parts for my car.

I’d rate 85%
Great aftermarket parts merchant!
Ordered a set of new Volk TE-​37 SL wheels from them for my POS car. Dynamic ran a pretty competitive ad on auto enthusiast website
.
The wheels would be shipped from the manufacturer, and take 3 months or so. They are ordered and shipped from Japan, so this is the norm.
Anyhow, both the price and time were honored as advertised, which was thankful. I received my wheels in great condition. It might be worthwhile to check some of their ads on
or
, as they advertise specials and/​or group buys where you may get a better deal.
Dynamic’s website was pretty informative when it comes to browsing the items they sell. For instance, there is pricing and wheel size/​offset info, and pricing is very reasonable all around.
They are open Saturdays, so that’s most welcome!
Only con is that they don’t always answer their phone. I sometimes have to call several times before anyone answers. I was also not notified when my wheels arrived. No calls, or emails. It’s not a huge inconvenience, but still that would have been a nice touch in customer service.
They do have a shop and dyno, but I have no experience with them on that.
Recommended! At least give them a shot, check out their site & request a quote for whatever car parts you might be interested in.

I’m local to this shop and I have been coming here since 2001 for maintenance and performance parts for all my cars plus all the labor. I started out building a Honda and now im building a 240sx S14 and I get all my parts from Dynamic Autosports /
.
THEY ALWAYS HOOK IT UP on the price, and they can get some of the most rare JDM parts out there. All the guys that work there are all really cool Automotive Enthusiasts so they know what they are taking about and are really one of us. They are a LEGEND in the Import scene and build the craziest cars like the Dynamic Autosports GTR thats drifting in Formula Drift. I highly recommend them!!!

Eddie always gives a great price and great service. Got several sets of tires from him recently and am very happy with the purchase. The Hankook v12’s are awesome!

Legendary reputation and boy can they build fast cars. Best prices in town, in house Mustang Dyno, and the fact
always has the best advertised prices!

I heard about a special on tires (after shopping around for quite some time), called them, was given an amazing quote.
I can’t always say that their prices will always be this amazing, so I’ll comment on their service.
Whether it was over email, phone, or in the shop, ever single person I spoke to was pleasant and polite.
My only minor complaints (which certainly don’t stop me from leaving 5 stars) are that the hours that they’re open and that they would fix the arcade machines in the main room, they’ve got some classics in there that are just begging to be played. Either way I’m sure they’ve got their reasons for both
At the end of the day, I was able to get my tires installed quickly, they’ve been running great, and they are definitely a company I would do business with again.

Dynamic is a tuner legend. They are one of the original shops, I believe theyve been open for around 20yrs now. They have built some big name cars and continue to do so now!
Dynamic/​Gruppe-​S Engineering has great pricing and stocks lots of items! They also service cars and do installs and tunes.
The shop itself is one of the nicest around… Its huge, clean and setup really fun. There are mangled pro-​drift car bumpers everywhere and the HUGE Dynamic stamped turbo is right in front. The shop dog Harley is super awesome — I think he’s one of the best dogs ever!
Whether you need a few things on your car worked on or need to purchase a turbo — this place has and does it all!
