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!

so long as they are both the same ID and coilover springs i don't see why not.

What kind of adjustable links do you have?

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.

If it is a 2.5 inch spring, it'll fit. I have QA1 springs on my GC collars. Watch out, the 500's are already maxxing out the Koni Sports. They will be unable to control any higher rate of spring.

The racing beat one IIRC. I have the front bar on the stiffest setting, I remember it being a real bitch to get them installed on that hole. I don't have a rear bar

Thanks for the input... will be looking from some new struts as well then!

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.
Wrong ratio's:

* .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.

I wish mine was that easy to adjust. I'll have to get new springs. My perches don't screw up and down. :(
