67 Firebird Rear Leafs. . .1.5" or 3" Drop

[atomicjoe23]

I'm getting ready to order new rear leafsprings for my 1967 Firebird (400 Pontiac engine/TH400 tranny) and I was wondering if I should go with the 1.5" or 3" drop leaf springs.

I haven't decided which brand yet. . .between DSE, Hotchkis, or Global West.

The car will see some street driving, but my goals are autocross and road course track driving. . .I have a set of coil springs I picked out after reading on the Pozzi Racing web page(I think they are the ones for Blazers. . .I can't remember which part number they are off the top of my head, but they are substantially shorter than stock and substantially stiffer), a 1 1/8" solid front anti-sway bar (Hellwig. . .I can't remember the rate off the top of my head), Kore 3 C5/C6 GM big brake kits front and rear, Koni shocks front/rear, solid aluminum body mounts, and Energy Suspension polyurethane bushings all around. . .this is my starting point for my first season of autocross. . .I will be adding tubular upper and lower control arms and switching to coilover shocks I nthe future once I get some driving time under my belt.

I will post the front coil spring and front anti-sway bar rates after I get home and can check them.

I just don't want to end up too low vs. the front and it looking weird. . .or affecting the handling.

Thanks for the help/suggestions!!!
