Lots of good info here  Thanks

I've run FLEX-A-FORM fiberglass mono-leafs...   they worked with me to design the correct setup... had a cpl choices... settled with 225# having a 5" uncompressed arch... settles at ~1.5" compressed arch with a completely empty trunk and ~1/4 tank of fuel... for autocross purposes (and settles a bit lower IF I put some load into the trunk and/or back seat for driving).   I've had these since ~1988 and they are great!

When replacing leafs, you first need to know the rear wheel weights (per axle/tire)... then determine how much rake or lift you want... flatter leafs = better handling!... arched leafs defeat handling.   

IF I'd ever replace my leafs again, I may go ~250# with a 4" uncompressed arch.


Weight savings is a big concern, as well.... that's why i chose Flex-a-Form.... they are OE for the Corvettes... proven reliable!... good people to work with!
