Help! 63-64 Ride Height Chg after Install of Heavy Coils ??

[charliebates]

Hopefully someone can help me with this.

If you take a 1963-64 Corvette with 327, stock coil springs and change to the heavier 460 pound, what could be expected for the difference in ride height?

Both are new coils and they are the same dimensions only the stock one measures 12-1/2 inches high and the 460 pound coil measures 15 inches high.

Thx, John

The '63 and the '64 front springs are different. The '63 has equally spaced coils, the '64 has some coils more closely spaced.
Measure the wire diameter of both springs, count the number of coils, and double-check the length (doesn't make sense).

The equally spaced are linear and the other is a progressive spring. The linear compresses at a constant rate. The progressive has two rates; once the soft rate is used up, the firm takes over.

For the curious, here is a better explaination. http://automotivethinker.com/suspension/linear-vs-progressive-rate-springs/
