it may get better legs, but the large track i run, everyone runs modded P5's, 421B's, and a few Vspecs. a stock P5 will not keep up on the top end, my Vspec will. the track is large enough that top speed is important.
the large track is www.hobbyhut.com located in King of Prussia, Pa. its not really condusive to bashing because all the onsite power and water is provided by gas pumps and generators which are stored when there isnt a race. its also VERY dusty even when prepped. its not the track that people are comming to race at in october, however I'm sure we could go there if the group decides thats what they want to do for sunday. sunday is supposed to be a bashing day however, and the hobby hut is a very competetive racing environment.
