I got to go to the Trans Am race at Sebring over the weekend and it was interesting. All the cars I looked at were tube frame race cars. Theres 4 divisions and from what I could tell the TA class could run a 358 v-8 and were mostly corvettes and some mustangs. Only a couple camaros. The mustang bodies, all were conposite, were wider and really aerodynamic in the front. Might be why you didnt see many camaros. The corvette looked pretty stock. The middle 2 classes,TA2 AND TA3, used the stock engines and must buy them from certain builders and from what I was told couldnt touch them. Seemed like an IROC class. The cars were still tube frames and race cars. They seemed to have rules on the amount you could spend on shocks and brakes and such. It was interesting, corvette and camaro could use the 7 liter while the mustang was stuck with a 5.0 coyote or the new voodoo motor. The GM cars had thorottle body size restrictions and most of the cars had some kind of weight which the GMS tended to be heavier. It was real interesting. One guy with a camaro in the stock motor class said in the back straight he was hitting 158 mph. There were about 6 cars in the slowest class, TA4, and some sounded like 6 cylinders but I didnt see anything online about what they ran.
Sad thing, I seemed to have deleted the camaro pictures I had of the car with the hood off!! It looked stock and even had a SLP cold air kit on it. Soo, you get pictures of Peter Klutts Dream Car Garage Challenger!! Not many Challengers there.
Sebring is an old Army airbase and a rough concrete track. The pits were all concrete and was a nice place to look around.
