This is a crap shoot, but whatever. :shrug:

looking for stiffer springs for the Bilstein track pack coilovers

front: 400 LBS or stiffer
rear: 550 LBS or stiffer

must be 1.88 or 1.87" ID and front: 8 inch tall and rear: 10 inch tall
so basically same demensions but stiffer rate.

:wallbang:

tried that
only sells the springs with the Penskes.
I need this specific size

I know they have a TP spring that stiffer. Or at least they did.

phone them up.

Don't get 8 " and 10". The stiffer springs don't compress as much as the stock ones so when you fully lower the track pack the fender gap will be larger. Ride height will be higher. Get 1" shorter for both.

Eibach may be able to supply those for you. They're in Corona 951-256-8300. Hope you find 'em.

it appears that no one makes springs that are an odd number
like 7" or 9", doesn't exist. :shrug:

you have to get them custom made. I think hypercoil can do it. I researched this last year, but i don't remember since it's been a while.

I would say 8" & 10" is fine, but the problem is the shocks don't have enough threads on them to lower the car further. That's why I say get 1" shorter springs, unless someone can add threads to the shocks. Or at least swap out the nuts for thinner ones, if that's possible.
