The fronts are 225/50/15 BF Goodrich Drag radials, which are good for drag racing, but have too soft a sidewall for circuit.
The rears are 225/50/15 Toyo R888 semi slicks are are amazing when they get up to heat on the circuit.
They are both street legal, but I have now replaced the fronts with a set of 245/50/15 Dunlops and unbelievably I get full lock to lock without any scrubbing.
