first of all... do you think you will prefer a "sticks" style transmitter or a "steerwheel" type?
secondly, if your new, a 5.5 will probably be too fast, no offence
id say go for a 7.5 or a 6.5 tops.... i use a 6.5 in both my cars and they are rapid!!!
also check out some second hand stuff before you buy new, it ma save you a fortune
what about this to start you off.... its a B4 but more of a basic kit.. (less fancy expensive parts such as the titanium turnbuckles, blue bits that you dont really need ete etc)
