Spring rating Please help.
What are the spring ratings on a stock '99 Z28 front and rear?
What are the spring ratings of the Eibach Pro Kit (for the LS1)? Are they progressive?
Note I am trying to find out the spring rating for the LS1 Eibachs, not the LT1's.

Re: Spring rating Finally, I have the spring ratings for Eibach Pro Kits for the '98+ F-body's with the LS1 engine.
The Eibach part number is 3870.140 and the rates are:
FRONT - 70N/mm (400 lb/in) LINEAR; and
REAR - 14 - 24 N/mm (80 - 137 lb/in) PROGRESSIVE.
This information was confirmed by Eibach.
Note the spring raings are different for pre '98 cars, ie LT1 cars.
Thanks
Jagsy

Re: Spring rating Interesting...
For frame of reference, the stock 98-01 Z28 springs are 290 lb/in. front (LINEAR) and 115 lb/in. rear (LINEAR).
The SLP Eibachs are 223-448 lb/in. front (PROGRESSIVE) and 97-136 lb/in. rear (PROGRESSIVE).
Just an FYI (and to help with future searches on this topic).

Re: Spring rating I just got my Level 1 kit from SLP and the front springs are marked 300/400. Is that their rating? <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />
