My car has the Caltrac's preloaded ONLY on the right side. 2 flats on the right and just touching on the left.
I bring up the RPM on the footbrake to 2400 at the beams....any more than that seems to take away 60' as the rear will start to rise a bit.
This is with a 4600 convertor and 3700# race weight and car will run 1.46 60's.
My assumption is that "torquing up" the suspension is defeating the purpose of Caltracs.
