I don't know...there are alot of fast and (F.A.S.T.) cars running regular street tires.

Some classes are based around regular street radials now...If someone wants to try to put down numbers on a small street tire...why stop them?

To be honest, I feel no different about a 3/4 ton truck running than a brand new blue mustang hot lapping all day...

I plan to enter next year, providing it is a little more north (as I have no trailer to haul my junk), but will be in SRBB-NA or DD. No bar limits me to 11.50, so I won't be competitive...but it should be fun...
