I talked with Gary before I bought my new wheels, and actually while I was thinking of buying his car...
They seldom ran the SubZeros because they were narrower, and barely cleared the brakes. I believe he said they had the rain tires, and a set of backup scuffs on them. The RP-F1s were the primary wheel, and they held up real well except when he banged them into stuff.

He reccomended them.
The MBs are about 18lbs, and are $112 ea. from Discount Tire. You could get tehm pre mounted and balanced with a set of RT-615s. So far, I am getting good feedback on autocross performance for them from the Evolution list.
