I have read that when jacking the car up and down with GC coilovers the springs will become displaced. I do not have any personal experience with this and will be jacking the car relatively frequently to switch between street and race rubber.

I am wondering about the people who have GC coilovers i it gets to be a pain to make sure the springs are seated properly if the car is frequently being jacked. I assume that it is probably not a big deal AT ALL, but just wanted to hear from someone with firsthand experience before I shell out the $$.

I could just go with springs and shocks, but want the option to change ride height if I do encounter too much tire rubbing or scraping.

wheel/tire sizes are 235/40/18, 18x8.5 +45 offset and 275/35/18, 18x9.5 +45 offset (street setup, not worried about understeer). would I encounter rubbing with a lowering spring/shock combo instead of GC's?

 

If spring alignment bothers you (it bothered me on my car), you can get helper springs and a mini-spring perch (sorry, but I can't remember the real name) that sits between the helper spring and the real spring. That will keep the springs aligned with respect to the dampers at full suspension droop. I think that GC charged me around $20 per corner a few years ago.

If you don't already know, helper springs are essentially zero rate springs. You can compress them completely with your fingers.

 

Suppossedly, Ground control has fixed this problem by including several "dead" coils in the springs that keep the springs seated while the car is off the ground...

 

I've never had a spring seat wrong after jacking (I'm running the M2/GC conversion on GAB super-R shocks). They seem to take care of themselves.

Doubtful. I run the same sizes (ok, 265/35 in back, but that's not an issue anyway) and have zero issues with rubbing in any kind of normal street situation or at the track. And my car is very, very low on HKS springs and Koni shocks.

You will, of course, have to be slightly careful entering steep driveways and such, but you will have to do that because of the lowered front end anyway.

 

thanks for the info guys, good to know.

On a side note, does the spring length or the GC mounts determine the amount of stroke lost in the shocks?

What are the recomended spring lengths and GC mount position to get a balance of lower ride height without losing too much suspension stroke?
