For years speedmerchant wgt cars had wider rears than any other brand because the where designed for Jaco rims witch are different offset from crc/bsr wheels so those with speedmerchant cars had to either buy different hubs or narrow the wheel. Also it doesn't matter if you have a tire/wheel sponsor , you run what the race tells you to run or you don't go to the race right ? Touring car drivers sponsored by sweep run Jaco's if that's what the race there going to is using so why can't it be the same for 1/12 ?
I was hoping the Mile High Indoor Champs was going to be the first race to do a 1/12 spec tire because Mario is a supporter of wanting to do it but didn't happen, maybe next year.
