Has Anyone Tried This Ground Control Kit?
Just curious if anyone had any experience with this kit - https://groundcontrolstore.com/colle...gle-adjustable
I am considering it for mixed track/street use and this seems like a well balanced cost/benefit.... Anyone?

Looks good. I like the m3 rear. Dampers will be easier to work with than the nonM. Based on koni too.

My friend who works at Eibach recommended the GC set you are referencing or these from TCKline for track and street ---> http://www.tcklineracing.com/webdocs...Details978.cfm
Biggest advantage is having the ability to swap out spring rates depending on how you use the car and both brands have a solid reputation in the BMW world Keep us posted what you decide I am debating both sets. |

If you're doing coilovers for good reason, I see no reason to go with a single adjustable.
https://groundcontrolstore.com/colle...ble-adjustable That looks to be a better option. Something that can grow with varying tracks, springs, tire's, etc. Vs a single that is all compromises. |

From my experience with GC on my S2000. They offer some of the best bang for the buck suspension tuning around. Paired with a set of basic Koni yellows these can be tuned very well. The key? Pick the right spring rates. Konis have low sensitivity and fairly soft bump damping. However there is a tremendous amount of rebound control that can handle a relative stiff spring. On the street they lack of sensitivity helped the ride, yet there was plenty of chassis control. On the track the spring rate kept the suspension from packing down and overall it worked very well for a street/track car.
I replaced that setup with a tuned Ohlins DFV 10k/10k setup and while it was better, it was not that much better. I would say the Koni/GC was 95% as good for about half the money. Regarding the kit for the one series, I assume they are using a Koni twin tube. I am not sure of the valving, but I am sure they bump the comp damping a bit. I have no issue with a single adjustable shock, however I prefer no cross talk. Konis are very good at this. Rebound will just adjust rebound. You can tune your comp with spring rates or valving. However, most of the time you don't need to change your compression damping. |

I am not that familiar with the 1 series spring rates however I know the front and rear have a fairly drastic difference in motion ratios. Because of this the factory rear rate is 3x (?) the front. 440/600 may be too little rear spring???
Wait... I just noticed you have a square tire setup. It may work well! |

Just installed the GC setup, M3 rear arms and Manzo adjustable arms. Yep. It's awesome. Can't wait to get it out to the track!

Here are some pics of the setup and car now. I haven't had a chance to take the wheels off yet but once I do I'll take some more photos.

GC kit is awesome! I've run it on my car for years! Their customer service is great too, when I did my M3 conversion they rebuilt the front coilovers with new housings to work with my new M3 spindles.
