Whats even more impressive, is John Kolivas showed up in Chicago back in July for the NMRA/NMCA race to run SSO for the first time and brought his 325/50's but since it is a 10.5 class the 325's were too wide. So he buys a set of the 275/60/15's and goes 7.3x at 19x and wins the event, with a single 94.
