Beat me to it. I agree. At one time I thought these were a band aid. Now I think they should be on most cars. Get one that's heavy enough to do the job.

Also, IMO 150# springs are way too heavy. Much like a six cylinder type spring on the front stores energy and helps the front suspension to separate and transfer weight, a light spring on the rear wound up a few inches also stores energy and helps get the rear out and applied at the hit. I prefer to use a light spring to accomplish that and use the shock to control the speed. 110s may be a bit too light once you raise the front of the bars, which I agree should be tried. Tightening the compression should help keep the rear out and applied and reduce the basketball effect of the tires. A rough racetrack may limit how tight you can run that knob. Also, I'm not sure a stiff sidewall tire is what you want. The stiffer sidewalls tend to want to bounce the rear back up into the car more so than other style tires.
