Im using the RCRD -5 Chassis with the truck 30deg front block and zero caster block. The more kickup transfer more weight in the back on power and seems to help my car on corner exit. I also have weight on top and in the front of the tranny. My car finally has the same level of traction as my teamc Evo. I had good success with the yellow rear spring but I'll try the white next race day.
