1971 Z28 Suspension & Chassis Component Information

This file is a mess, but I'm trying to consolidate the spring info, the suspension info, and the yearly info into a more readable, manageable and informative package. It'll also make proof-reading and catching screwups and obvious conflicts easier.

Front Suspension: Z-28 anti-roll bar 1.0-inch diameter instead of standard 0.6875-inch unit. (identical to 1970)
Front Springs
Part #   Code   Deflection Rate   Curb Sprung Wheel load/wheel (LBS)   Load @ 11.00" Checking Height
3982345   EJ   300   0 - 847   1920
3982346   EN   300   848 - 877   1980
3982347   EO   300   Over 877   2040

Rear Suspension: RPO F-41 special suspension standard, including 5-leaf rear springs, 125 lb./in. spring rate, staggered heavy-duty shocks, link-type rear stabilizer bar (unchanged from 1970).
Rear Springs
Part #   Code   Deflection Rate lbs/in   Load @ .71 Spring Camber (LBS)
481992   PK   96   735

Steering: The 22.5:1 unassisted gear became standard, with variable-ratio power steering now at 15.5-11.8:1 for all Camaros-not quite as fast as 1970.
