On this topic - DOES any know if the ERS springs (for the spec) will work with GC coilovers? They say it's for the AWR coilovers, but dam if I need to buy a whole new suspension system! I have 500s in the front now and I'm getting some wheel well rub in hard barking and cornering with my 225/45s. Running Koni adj yellows with my GCs. Thanks guys!

I had ISC's before they froze up. I was in a hurry installing them and didn't use antiseize. The new set are 1/2" teflon coated dirt track shop specials.

So hypothetically if I wanted to lower my ride height by 1/2" all around, I would need to adjust my coilover perches downward by...
.5" / 1.34 = .37" front
.5" / 1.26 = .40" rear
That is a question. I'm not really going to lower it another 1/2" just yet but I want to make sure I'm understanding the concept correctly.

* .5” / 1.52 = .33” front
* .5” / 1.36 = .37” rear

Cool beans. That gives me a ballpark idea of how much to adjust. But I'm still not going to bother with trying to set a .04" difference between front & rear. Fine adjustment of the spring perches will be determined on the scales.

I decided to take advantage of this glorious 75° afternoon and degrade my car from balla' status.
I applied the following:
LF = 11.50" + 1.0 / 1.52 == .65" collar increase
LR = 11.75" + .75" / 1.36 == .55" collar increase
RF = 11.75" + 1.0 / 1.52 == .65" collar increase
RR = 11.75" + 1.0 / 1.36 == .74" collar increase
Getting as close to those numbers as I could, the car is sitting pretty at exactly 12.5F and 12.75R. So I'd say those are the numbers to use.
