So I am running a t4 (not 4.1) and after changing the gearing, I just threw it on the track stock at WCRC and it pretty much drives itself. Handling is that good.

Is there much differance between the 4 and 4.1? Also, does anyone have a preferred setup for clay (WCRC) they can share?

Thanks.

Cannot believe how nicely the t4 drives stock.
