Default Springs for road racing, lowering with 315's

It's about time to get a set of lowering springs for my 1998 Z-28. I have 17x11 TT2's with BFG 315's out back which concerns me about rubbing issues. I want a set that works the best for road racing and autocrossing while dropping my car an inch to 1-1/2 inches all the way around. I know I'll need an adjustable panhad rod to center my rear but will I have problems with rubbing the fender lip? Give me some recommendations, thanks!

I have the 17" TTIIs w/BFG 315s on the rear. Lowered 1.25" w/Strano springs and w/Koni SAs. Even at Road Atlanta, my tires never touched the fenders, front or rear. And that was with some heavy cornering. I did have some rubbing issues on the inside, but used BFH mod to fix it. When I had the Sumitomos on the rear, there was zero rubbing issues. The BFGs are about 3/4" wider. I have a thread on here somewhere with some pics of my car hard at it at Road Atlanta. It is a great set up for the track and for a DD. I hight recommend the Strano set up.

+1 on Stranos.
Rates chosen by a successful autocrosser (Sam Strano), and 1.2" drop. They seem to be ideal 4 u. I will also have these on this season.

+2 for Sam - I have his springs too

I slapped on some 315's BFG's at a 1/4 mile strip, no issues at all.

I know it's not road race but drag racing does put some good stress on the car (burnout and launch).
