The easiest, lowest cost and simplest way would be with custom coil springs. I'm doing the same thing right now on a non Corvette. You won't have any geometry problems if you only go a couple inches and that should tuck the tires up into the wheel wells nicely. Check with Guldstrand and others that offer suspension packages for the Corvette. Often a performance spring will be shorter to begin with.
Welcome Carnalsupply, to the CACC. That's one beautiful Corvette, man. It nearly brought me to tears. Simply wonderful! On the lowering issue, did all early Sharks come with the 10 coil spring? I'm not with my '71 right now, so if anyone knows off hand, please share. I know that alot of the aftermarket companies sell the 7 coil spring as a better replacement. Thanks. --Bullitt
By the description of your '71, it's no slouch either
What it looks like is (as I've been preaching to some of my other Corvette club members) our Corvettes are nothing more than your standard Chevy dressed in Fiberglass clothing! So all the same front end stuff I learned on Chevelles etc. over the years will all apply.
