Took my RT to the Street Machine Summer Nationals this year and decided why not take it out for a little run on the autocross course?!
It's completely stock with the exception of 275 width NT450 tires. It had a tendency to push the front end pretty badly which I expected with how much weight I've got.
It ran a 35 which was what a lot of corvettes and mustangs were running. The faster cars like a couple Vipers ran 31-32's and the fastest car ran a 30 I believe.
