idk off hand. but a rule of thumb to remember, the shorter tire you go, brings you closer to your rev limiter when you trap. for example with a 5 speed, if in the end of the quarter your at the top end in 4th gear, and go with shorter tires, its gonna hurt you slightly to have to shift into 5th at the end of the track.
idk what kind of tranny you have either, but for a guess i would say that M&H makes them 23 inches tall and 24.5 tall, which are pretty close to the stock heights on our cars.
maybe someone else can chime in here.
