U2TC came about because of the influx of V8 lard buses when the $ was worthless making it cheap to go faster . . . . then after 2 years U2TC exploded into an arms race of development never seen before. That kind of development is now the norm, to the point you don't have to bother with development, you just buy a new car which has had all the development done before you sign the cheque. Win a pot with it at a big meeting then flog it the week after!
