I,ve only tried it once in my old civic and I had a blast. The only reason I didn't do anymore was some scheduling conflict and I lowered my car way too low. I think it might be a little hard at first with the WRX since you have to keep the boost up. Jake seems like the only person to really flog his car through the track. I would watch him first then try to emulate. I think the RS with the right setup would be just as good. Or maybe not......RALLYX13?
