Buying cragar dragstar rims with 28 x 9" m/t slicks for my 5 speed nova and looks like clearance between sidewall and 3 pack leafspring is only 1/4". Thinking this is too close at track and wondering if my better bet is to add 1/4" spacers or grind clearance off sides of springs 1/4"??? Springs are currently 2.5" wide. Any opinions or recommendations on this would be greatly appreciated as always. Car will run 12.0 at 111mph!! THANKS MUCH , AL

Don't grind the springs, you could stress and crack the springs. You can actually order narrower springs for your nova through a good spring shop. I heard the maximum for a wheel spacer is 3/16". Make sure it is a good quality spacer or it can crack, may not run in balance, and/or warp from what I hear. To me, they are band-aids, just like extra long spring shackles and crimp-together wires.

AL; If you do end up with 1/4" clearance,you should be just fine.At high speed the cross section will shrink,if anything.You'd have to be cornering at 1g or more to touch,and then it would only scuff the tire.But I doubt the springs would bow 1/4" laterally over the entire length,let alone in the 22-24" area at your sidewalls.
