I had a freakin fantastic time. I'm really happy with my times, I ran a 68.4, with my pretty standard 34GTT. (fmic, cai, 3" exhaust, tein type RA's, street tyres)
In my first time out there...nervous as hell... I flog it out of the pits hit the first corner at about 120 and pull off a 720 degree spin lol... I was a bit scared of that corner for the next few laps hehe.
I was probably one of the slower cars there, but i still had a great time. It makes me think about spending lots more and grabbing an oil cooler and semi slicks...but I dont think I would be out there enough to make it worth it.
