Gonna run TT this year, plus do some NASA instructing. Got a 05 GT to DD and serve as a light track car. When I bought it ... Haven't done too much ... yet. But not planning to. Staying in TTD class really limits my modifications. Basically a stock 05 GT classes TTD and only has 5 points before TTC. So, my CAI is +1, some non OE swaybars is +2 (these are from a Brembo GT, $50 on craigs ) and +1 for running 255mm tires instead of the D class 245mm. Not sure what else to do with 1 point, but here's how she looks with the new wheels. I picked up some Brembo GT wheels with 255 Pirellis for $600. Not a bad deal, drove them today for the first time. Definitely some sticky rubber. Definitely a little deflated when I weighed it. 3700# with me in it!! I gotta shed some weight somewhere.
