Is anyone running 40 series tires? I have started autocrossing my 633/Dinan turbo. The stock 70series 14" just can't stand up to the torque and cornering loads. I have found a set of 225-40ZR16 Toyo take offs(the guy's Neon could barely turn them, imagine that). Any help appreciated. Ross Ft myers, FL 633csi, turbo, springs, bars, not enough tire.
