Pro-am FWD in the idrc I am wondering what others are doing about the 8.5 slick rule--- So i couldnt use the 25/8.7/13 like many others run --whats the deal??

 

Simple. Run 24.5x8.5x13 M&H's which alot of these guys run. I believe this is the size Mike @ motormatrix ran when he went low 11's on his last outing. He wasn't running full boost, but close to if not over 500whp. What kind of power are you putting down?

 

i think he was running the 25x8.7x13

 

Run 25x8x13's, thats what i run, Ran my 11.0 on them, and have much room for improvement, Id say their fine IMO

 

Good input ill stick to the 25*8*13's see what happens-- Intentions of 500+whp everything will be ready for tuning the week of july 7 we'll see

 

I just edited my post m and h does make a 25x8 go figure, but I know most run 25x8.7 . I would email idrc. Jason
