Hey BBLM23 Rear suspension
I tried running the stock six leaf springs with an adjustable snubber and a few clamps, it didn't work very well. I added the Caltrac bars and adjustable shocks, it worked nuch better. It would hook on good track prep race days. On Wednesday nights, which is when they run the Pure Street class I race in, I would get two time trials with 1.65 60' times. Then I would spin the tires badly as the night went on. 1.73, 1.85, 2.05 60' times. I got annoyed, played with launch rpms, changed the front springs, and put the 30x13.5 MT ET Streets on. It didn't help. I put the Caltrac Mono leaf springs on and haven't spun the tires since. I made a pass in the rain, (I had my wipers on!) but it didn't spin. 1.62-1.67 60' times and I haven't tried to adjust them. The Caltrac bars, shocks and Mono leaf springs work great for me. Now I can try all the things I have to make it faster. Jetting, Super Sucker, I have 2 convertors laying around, bigger tube headers...
Oh, my springs are moved into the frame rail.
