Just Released, Ground Control Street System

[GC_Adam]

Hi All,
We've just released our Street System.
This system is designed to use the factory strut/shock mounts and bumpstops. We are still using our custom made in house GC strut housings, GC coilover hardware, Koni top adjust sport dampers, and Eibach springs(custom rates available). Our Street system is designed to give you the ability to lower your street car and still provide you with the ride and performance you've come to expect from Ground Control, Eibach, And Koni.

What do you recommend for street use ? I saw the optional camber plates and bump stops. Are these needed ?

Thanks

[JoeBoxer]

I would get the bumpstops for sure, camber plates and stuff you might as well get the Touring system if you are going to add that much to the price.

So basically these are about the same as the other set up you guys have just not with the top mounts and integrated strut brace?

If so I want reviews as im in the market for a nice reputable system

Kid, Yes you are correct.

I'll have a couple members reply to your request.

I got the next level up product but have yet to get it onto the car. Sorry I cant be of more use review wise, till mid January .. I also considered the KW3 and decided these gotta be as good if not better in a bunch of way they are exclusive in, and in my analysis, superior, a little more of a production look than the boutique look of the kw3, but koni is prolly better regarded in porsche and bmw communities, so that weighed in heavily for me. Warranty is top, build and safety and such is as good as it gets. I have faith I will be pretty happy with these..

I will share what I can till then as far as I can as a pre install review:

They are stout lower strut front housings and they machine a burly RSM that no one else does. SO far, cornering the market in this regard. Pun intended.

Welding on housings looks way overbuilt, perfect for R compounds and a driver looking to explore the limits of grip, and my capabilities. I have room to grow, so the added cost of kw3 or ohlins was not justifiable. I traded off rear adjustability for a bunch of other things, and am sure it was right for my track toy build. If I ever really miss the rear adjustably, its not a huge pill to swallow, and I can bet I will never miss it.

However,I dont think ANYONE makes a camber plate as stout. Obscenely thick. Good. This thing is sick thick. If the goal is to prevent camber change from flex and loading, this setup oughtta do it if anything will. I like that alum's flat bar shape from a design perspective, that wont distort under load and uses wide anchor points, high spec hardware and yeah, it looks so fine too.

If these are important as part of what you want to do to augment the rigidty of the mount points, then you need not look further at other solutions as there are none other as inclusive at this pricepoint. IMHO.

Getting them serviced, revalved, etc, is non issue.

I went with it based on value and performance goals, as the spring setup I'm getting 375/430 keeps much of the cars factory bias moving CG rearward a hair, which is fine for control outta corners,and under hard braking, since there really isnt any understeer with sticky tires.

My usage of the car is recreational track. I like what the strutbar looks like, and that its a wide cnc'd pc of billet.

As a brand I track on my other car regularly, I know what to expect as far as longevity and results. Koni is a big firm, with oodles of R&D, and refinement of processes and parts.

GC's attention to detail in M3-land, something as simple as the machined insert their sway bar endlink kit shows what level of anality your getting for your money here, as a complete solution. Price wise the kw3+vorschlag solution + strut bar, well GC wins everytime. I dont doubt that the kw3 is good, but I dont have dual adjustable rears on my m3, and cant say I miss it the least, the rear dynamic weight transfer is matched spot on to the cars weight and valved nice, it is well matched to the on the fronts; when I went to grabbier front brakes, i went up a click in compression up front, so dual adjust fronts were mandatory for me, I usually match the front to the rears as a departure point, and that has worked well for me.

Good luck with your choice!

*KID*, I have the complete GC setup on my FR-S that I bought from Adam at GC 7 weeks ago.

My weekend FR-S fun is autocross and the car is also a daily driver.

I called Adam with many questions and told him how I wanted the car setup and asked for his input. He answered each and every question and put together the setup I needed based on my needs. There was no "I'll have to order this or that" because they build their own parts and have everything on their shelves in stock.

My setup is Koni S/A shocks front and rear, GC camber plates, GC strut bar, front and rear springs with his recommended spring rates and a few other things I can't remember. He even sent a second set of springs in case the first set were too soft.

Had only one problem after everthing was installed and an alignment was done. I wanted -3 degrees front camber and -2.5 rear camber. Rear was fine but my alignment guy could only get -2 degrees front. Discussed this with Adam and he had his engineers build a different set of shock towers. Got them 2 days later and was able to get -3 degrees front no problem.

The car is very comfortable as a daily driver with the Koni's set at 2 clicks from full soft and my autocross times with the Koni's set 1-2 clicks from full stiff improved big time! I run SCCA's STX class which is mostly E36 series BMW's. Before the GC upgrade my times were just so-so but after the upgrade I'm very close to the top 2 drivers in the class and they are worried about this new car in STX.

There has been one other problem since the GC upgrade. When I open the hood for tech it draws a crowd <grin>. I have GC camber plates and the GC strut bar both in red.

When I need to speak with Adam I used to call but now I just email him. He always replies to email within 10-15 minutes.

I highly recommend GC and Adam, best darn service and support that I know of.

Any other questions or concerns that you may have just send me a PM.

Thanks

I DD my FR-S. I go to car shows every weekend pretty much. I need a nice drop, maybe 2-2.5 inches. I want to maintain the stock smoothness of ride. I don't track it and don't plan to. Something cheaper than KW V3's. But something of quality that I can rave about. What do you suggest for me Adam?

The Street or Touring systems would be perfect for your use. These are designed for the guy that is looking for a street feel in the drop range your looking for. These systems will achieve upwards of 3" and still give you usable travel. The Street system will reuse your stock strut/shock mounts while the Touring system uses our camberplates with urethane bushings to help isolate noise and road vibrations and gives you more travel over the stock mounts.

This kit looks great. very interested

[CSG Mike]

I've had friends have GREAT results on their cars with GC setups.

Looking forward to come reviews

[bgibbsunc]

You have a pm adam

[OICU812]

Not much chatter about these, anyone else here get any of these and have any feedback??

[Enraged21]

These were definitely on my wish list. I would like to know how these compare to RS*R Black-I Coilovers. But I like the fact that these camber plates add about 1" of suspension travel for the front struts.
