Listen, realisticlly all you need is a track and a set of skiiis to have a damn good time bracket racing.I see jabber800 has a set for sale on here,if not there let me know I have made them.When you you want to play with with the big boys(there is alot of them)you get into ignitions carbon fiber everything big boring (however I've never seen a vmax4 bored to match these 1400 actic cats or doos)and aftermarket front and rear suspensions.Ideally you want to get rid of ANY extra weight.
