I've got a 2000 Z28 full bolt on minus a pulley and a Torquer 2. The GT500 has a 4.10 only and will be on street tires. I'll be running a 245-50-16 nitto extreme drag radial. The run will be uphill as well. For reference my friends lid only A4 ws6 only lost by a car in the same spot to the same car before he added the gear.
