My track car is a Porsche 911tt and works for me. Also, a used Cayman would do the trick also. By the way only the Cayman and Boxster are mid engine. The 911's are all rear engine! Unfortunately they are all 6 bangers (although my tt puts out about 525 AWHP).
Also, have seen a few Camaro's at the track. A bit of suspension work, a little brake modification and you have a pretty good track car.
