Just out of curiosity what is everyone running for wheels on asphalt ovals? I'm running a 6" LR and a 6.5" LF. I have seen other guys running 6" front and rear as well. I'm running a 1/5 mile oval.
I run both, some guys swear by only 6" wheels on the lr, but I have found 6.5 to work better at certain times. The LF either a 6 or 6.5, usually to get stagger instead of shrinking or stretching.
