In my 85 CRX Dx setup for ITC, I have an adjustable rear ~3/4" sway bar and 600 #/inch springs which combined with the front 21mm sway bar and either stock or maybe 23mm front torsion bars, the thing is pretty quick and body roll is not too bad. I have either a stock final drive or SI and the Mugen LSD which works pretty well in the midwest.
