are u proposing thes cars race in a seperate class or are u going to do upgrade kits ?
if ur having the chassis redone for the front end how about a series of holes for the front bumper so u can move them to adjust to the body
or move the holes for the body mount holes back 5mm so u can get the steering arms straight,i noticed u had different ballcups on ,does this do away with the issue,
not having a pop at u or the car ,just thought while ur on here and modifying the car that theres a few small tweeks u could address while not costing huge development and molding costs
