1980 Z28 Suspension & Chassis Components

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: Spring rates 365 lb./in. Identical to and unchanged from 1977. (stock: 300 lb./in.) Stabilizer bar 1.125" (down from 1.2"). Stock bar: 0.938, F41: 1.0").
Rear Suspension: Spring rate 130 lb./in. (stock: 92-99 lb./in.) Rear Stabilizer bar 0.594 inch. (stock: none, F41: 0.5625)
Steering: Overall ratio 13:1 (stock 15.03:1 to 10.61:1 variable). 2.61 turns lock to lock (stock: 2.41).
