Heres how you beat the gsx. Ask him to race in your current state of tune. You will most likley loose if you're stock, but tell him you got a bad launch. Keep making excuses to keep racing. After about 10 hard launches the center diff should be getting weak, and hopefully put his car outta comission. If the car doesen't run, its not faster than yours
And the WS6, well...........NOS or FI is all I gotta say.
