On my clubs outdoor track I used to practice with the IC cars using my old XXX-S. Down the back straight I could stick with them until they hit second. Round the infield (which is pretty open) they were quite similiar.
Not bad considering this was against a Serpent 705 all kitted out for national racing...
Once they hit second gear they are long gone though... gonna take some insane speed car (or AJG's micro
) to catch one!
