I have a 1991 RS with the 15" wheels. Will i have to do anything to my springs to make the ride height right if i put the 91' Z28 16X8 wheels on it? Thanks.

nope, just have the right size tires and there will not be any problems. measure the diameter of you 15" tire and match that for the 16" then your speedo and all will be the same.

The stock (correct) tire sizes are very close to the same outer diameter anyway; close enough that the factory used the same speedo gears.
The OE tire sizes are 215/65-15, and 245/50-15. They're both about 26" diameter. The change in their diameter from tread wear, is greater than the difference between the 2 sizes of tires. Usually, most 16" tires in that size that you can buy at the store, are slightly smaller than the 15" size, that you can buy. Not all tires with the same nominal size, actually have the identical diameter.
