I wouldn't spend that kind of money on a car that runs 13's. There are much less expensive alternatives and ways to get the SS springs so the car isn't sky high. Flip the spring hangers over. I remember one suggestion of B body SS or the 2800# springs on the A's.

I know Sloan swapped out from SS spring to Cal tracks and the car made a big difference in 60' and the way the car left the line. Nice and level, no more left wheel high, car sit level now. It does run mid 10's so the comparison to your car isn't the same.

I don't run SS springs on anything I own.
