Tire Options.

Hello All;
I need the help of the Traction Kings as it were.

Prelims;
'75 Dart More Door
Mild teen, 0 deck, +.030, heads cut .020 with big valves.
TF904 with stage 2 kit. 3.55 SG out back.
Stock Suspension.

Been to the track 3 times with the same results.
Spinning Tires....:mad:
I have been told that is because of the BFG's on the back. (245/60 -R15)
I have about 1-1/4" clearance as it sits right now.

Question is, what should I put on it?
Trying to keep it on budget. (Got 2 boys in College)
I am open to D.O.T. Cheaters or straight street tires.
Car is a driver, not a track car.
I have read alot about tires and cannot decide. They all say great traction, long wearing, blah, blah, blah. So I am looking for some real experience.
Also, what do you think about Used Cheaters for the track only?
Auction house has some pretty good deals on them and I could put them on a pair of 'Track' wheels.
Anyway, I am getting ready to buy and need the help....
Thanks!
