me my brother and the lad who lives next door are planning to go racing at the start of next seasons racing

and we need some help with what we should buy
we would like to get 3 rtr cars as they are cheaper than kits and still fairly fast.

first off we were thinking about the ntc3 rtr as i have read it is very fast and an all round good car or maybe the traxxs 4-tec
is it says it will do 60 mph out of the box (bet that would make a mess of the living room at xmas) or is there another rtr which is as good or better

second is body shells
we want to use the new hpi rx7 boby
is this race legal
and does the shell affect the performace much as most ppl like to use stub nose cars like the dodge status but it looks pish. i hate yank cars (apart from the 67 shelby gt 500 ss)

third is wheels
i have read that the areo dish wheels give you better areodinamics than spoked wheels is this true and if so buy how much

thanks mj
