get some 18" wheels and run a 305/45-18 nitto 555r out back. set the pinion angle to -3 or -4* and run a stiff shock. i run the rancho 9000x 9 way adjustables. you can stiffen and soften them up.
no need for caltracs unless you start getting wheel hop problems.
if you really want some awesome street traction put on some 16" wheels and run a 28x10.5 mickey thompson et street.
