It's hard to say. I do a little stoplight racing, but I wouldn't call it drag racing. I don't spin the tires or anything.
Anyway I've got 140,000 miles on the original clutch & engine and she still runs strong. I think the ATX is supposed to be stronger than the manual, if maintained properly.
One really bad thing that can happen with our engines is oil starvation on long hard sustained turns. I forget whether it was right or left turns though.
