WE ran a 100# lighter spring in the Rf with a short 3 link around 15#RR to 15# Lr bite. Car worked very good. Only on a fast momentum track the 650 seemed to be too soft and would dive to hard into the corner and bottom out the 'a' arm to the frame. Used the angle in the LR trailing arm and panhard bar to get bite off.

The reason I asked about the rear suspension is because IMO, the soft rf works best with a 4 bar. Running a soft rf helps the lr up on the bars, and you have to get it up on the bars to get any bite. I run a 4 bar late model with a 500 lf, and a 275 rf, 100 lbs of bite, 53%rear, and have better traction than I ever have, but I had to increase my lr bar angle, and J-bar angle in order to get it to stand up on these bars. I can also drive it in deep with this setup. I'm still playing with it, but it is very fast for me.
