I do not recall if your tire sizes all end up being same height tire, If so, your car should sit lower in the back than the front. They were that way from the factory for much improved handling, and for the "Flush and dry" pressurized rocker cleaning system. Many people adjust their suspension for looks, or tire burn outs and they can easily loose it in a corner. Adding in Spring spacers is a big non no...That will cause stress points in the springs and will make your ride alot stiffer. Its possible if they are stiff springs already, you may end up negating the sway bar by putting them in. Just like putting in poly bushings and making them way to tight so they dont move can also negate the suspension function.
My front is 28 for what its worth, stock springs and 225/70 tires on 7 inch rims. Back is 26.75.. GM wants the rear down about an Inch on a brand new '70 T/A .. if this even matters...
IF you must spacer this car, use the rubber coil spring discs made for this purpose. NO twisting to put in either and its alot more uniform and they do give a little. Good luck!

Formula Bruce, I don't think these are the spring spacers you are thinking of. they are made by Spc performance or Global West and they are c-shaped aluminum discs that go underneath the front springs. they are for ride height adjustment on race cars

OK, thats sort of what I was suggesting at the end of my post, but I have seen them in rubber or poly...I hope your springs give enough to cornering traction. Good luck!

from what I understand these types of spacers do not change the spring rate.

Right, they would not affect the rate.
