Is the car lowered? Edit ....... hold tongue, get lots of seat time and let an instructor evaluate your car first. In no time you'll be doing battle with "well driven" Porsches, Corvettes, 2011 and up Mustangs ...... GTR's need a few more mods.

I recommend this because I know the difference between a well driven SRT-6 and poorly driven one

(memories) and the difference is huge. In any case, you're going to be thrilled every day with that supercharged beast.
I can hear the PA now, in 3rd place, in 2nd place and beaten by a Chrysler .... that's right, a Chrysler! That's gotta hurt. Do you feel like putting the hurt on?
