Kevin hit on the obvious...if the RX7 was as competitive as the GSR is, do you think there would be so many of them now? same for E36. It is painfully obvious that the ITA version is popular by number of cars out there. I would LOVE to see FWD vs RWD in the top rank (just like btcc Speed TC etc) but it aint gonna happen the way the car is now. If the SIR works as advertised and you could cap the Wheel BHP to 200 and lower weight...bring it on!! There are plenty of cars out there (i just got a SSB car for $2999!) and if it is competitive you can bet that they will come...........

Evan, One of the reasons you have not seen them is they are just hitting the "cheap enough to build and IT car stage" There seems to be a magical number that cars have to hit before they become popular for building racecars out of. The 240z was it for many years cause there were lots of them and they were pretty cheap. E36's didn't catch on right away even though they looked fast. 944's are finally hitting their magic number.

Can't wait for the march fastrack just to have a new thread to read....
