What spring rates are you using, what car and application?

FYI I'm looking for a rate comparable to stock for a TC.

Stock rate was ~415 lb/in up front and ~210 lb/in out back.

This would correlate to a ~115 lb/in coil-over spring in front and ~93 lb/in out back.

I currently have 275 lb/in coil-over springs in front with the factory springs out back. There is a definite mismatch between the front and rears.

The 275s up front are a lot stiffer than the factory springs, but they aren't really uncomfortable.

These guys have four choices, 12"/250s, 14"/175s, 14"/150s and no springs.

As I understand it, 14" is a bit tall for a coil over spring?

Jeremy, what engine do you have? Relocated battery? Any other weight changes?

Thanks
