I got my Ground Control coilovers today to replace my Eibach pro kits. I ordered 350 lb front springs and 275 rear and I'm pretty sure the rates I got are 150 front, 200 rear which makes no sense. I'm going to call them but I was wondering if anyone else has GC's, what rates they are running and opinions.



thanks

 

350/275 is a good starting point, you're in the ballpark

 

my n/a has the its setup i believe. It's like 400 or 450 in front 325 in rear. shitty ride, but turns like no other

 

I was reading the #'s wrong, they're in metric. The rates are around 370 front and 250 rear lb/in. Thats a lot stiffer than the pro kit rates. Hopefully it wont bottom anymore. The fronts are only 6" long and the rears are 8".
