And working around them. Here is the NNI racing STi we're working on at Designcraft fabrication. All wheel drives sometimes have a tendency to understeer. Sometimes alignment and tire choice/pressure will do... But in this case(Especially with the massive Prodrive WRC wing) it didn't. Time attack rules allows a maximum of 5 inches from the furthest point of the bumper. Looks like a lot more here but we just tucked the lower bumper in. So far, it seems to be working. This is the prototype made of hand formed aluminum. Future plans call for a "dry" carbon version using this one as a plug.
