Just some extra info for you guys.
The main aim was to build a car that suited our UK / European style of tracks which are mainly med/high grip grass or multi surface (astro turf). As almost all the off road cars are aimed at lower grip dirt style tracks (as this is there largest market).
Making a car as cheap as possible was not my aim, simply as you comprise the car, i use the best parts and materials i can get, some say this is over kill but this is my choice. I don't intend to mass produce the car, each chassis is hand made here in the UK so i cannot make hundreds of them
At the moment the cost for a complete conversion kit from a BJ4WE to a S4 is working out at GBP £250 (approx $475) and i am hoping to have a small number of conversion kits ready March / April.
In testing we have found the car to be at least a match for any other car, and to my surprise the car has gone extremely well on our only dirt track here in the UK, having won both meetings it has raced at. and last weekend Chris ran the car for the 1st time at Kidderminster (multi surface). All i can say is that if we can beat the 2wd World Champ driving a Yok BX with a year of development then we most be doing something right
@ dodgeguy the chassis is 4 inchs wide and the shell is just a little bit more than this. I think it would be to narrow for your chassis.
