Probably the Mickey Thompson 275 (10.5) as the car is built To be legal for Josh’s Monster Mopar rules. My local class at Quaker City allows a bigger tire but you better be 4.60-4.80’s to play with those boys. It was a great series several years ago but a 5000.00 purse started drawling in some hitters. I’m just a minnow in the ocean so I gotta keep it FUN. If I would start hacking on the car to make it user friendly I just lost the value of the car as it sits but it would or could be a fast bracket car.
