the better Dleta, the callzone or somthin, has been great to me. Throw in wheight reduct, flywheel, and a turbo and you got one great car. If you totaly modify it, you can change the horses anywhere from the 250 to the 500+ races...very versitile, and very fast (epecialy compared to the low HP racers). Worth a look if you havent tryed it. Anyone else get good luck with this thing?
