Post 964 Spring Rates
Hi all,
I would like to expand on some interesting information that Jeff Curtis provided about spring rates in an earlier message. Here is a more comprehensive list of spring rates for some common lowering and coil-over springs for the 964.

Please feel free to expand on or correct this information.

Eibach 964 Pro-kit springs (like mine)
Front 82.6-250 lbs/inch
Rear 188-256 lbs/inch

H&R 964 springs
Front 190-255 lbs/inch
Rear 220-265 lbs/inch

H&R 965 (Turbo) springs (Jeff Curtis)
Front 250-270 lbs/inch
Rear 265-285 lbs/inch

H&R 964 Coil-over
Front 250-285 lbs/inch
Rear 265-285 lbs/inch

H&R 964 Super Cup
Front 455 lbs/inch
Rear 685 lbs/inch

Porsche Carrera RS springs (Bill Gregory)
Front 250-308 lbs/inch
Rear 375-508 lbs/inch

Thanks to Jeff Curtis and Bill Gregory for helping with this information.

Erick

Joel Reiser actually was kind enough to supply those Carrera Cup measurements to me using his own spring rate tester recently.
