Ground Control/Ap1 Shocks
hey hows it going guys. ive owned my s2000 for a little over a year now and purchased it with ground control adjustable springs over the stock ap1 shocks. the car was always super low even at the highest adjustment and cant determine the problem here. i provided a pic to show how low it is at the highest adjustment, any lower would be rediculous in my opinion and something just isnt right. i discussed the option of blown shocks to my father but he replied the shock doesnt determine the height at all, it all depends on the spring. could the springs be bad? they only have 20K+ miles on them. i dont see how springs could go bad though. could something be installed improperly? the car rides alright, not bouncy and havent noticed any leaks so maybe not the shocks. if any has experienced this before or has any ideas what could be wrong please let me know, thanks.
by the way, i havent mentioned this is a problem only in the rear suspension. the fronts are fine, as you can see theyre higher than the rear and have room to go higher.

Can you figure out the spring part numbers? They should be visible on one of the coils. Sounds like you have springs that are too short for the rear. If the shocks aren't leaking, they probably aren't worn out. The internal valving can fatigue, but that won't have an impact on ride height, like you father mentioned. If they are Eibach springs, the part number will be XXXX/YYYY/ZZZ or something along those lines.
For example (if I remember correctly) -
0700/2500/300
XXXX = height [in], 0700 --> 7.00"
YYYY = inner diameter [in], 2500 --> 2.50" ID
ZZZ = spring rate [lbf/in], 300 --> 300 lbf/in
It's something like that... Post a reply with your findings and that'll help everyone diagnose your issue.

Yep, springs are too short. You'll still need to figure out the part number or remove the springs to measure their free length and ID. Maybe call Ground Control and see what the spring is supposed to be standard with the S2000 coilover kit.
Looks like you could easily go 1"-2" longer than your current springs, depending on the spring rate you choose.
