Caltracs question

As far as running Cals with SS springs, I ran my duster (mild 440) on just the springs for a while. No traction issues, but it did like to tire hop. We ended up putting Cals on the car and we've not had any hopping since. It actually picked the car up by a tenth. Never made a huge difference in consistant times, my car has always been pretty solid. Not sure about higher power setups. My 440 is cranking around 1hp to every 1ci.
