Regarding the axles, it appears to be an isolated issue. The prototype Boxster and the one completed after mine both have not had axle problems so far. The prototype Boxster is a track car with a more powerful LS7 in it (probably around 600 hp). I know the one after mine has been really put through it's paces as Scott at Renegade drives that one periodically. If you've ever driven with him, you know any car he drives has to be in top shape or it would fail. He's a great driver (one of PCA's senior instructors) and one who knows how to drive at the limit and does all the time.

We think it was a combination of issues that broke the axle and it didn't break dramatically. Rather, it appears the boot failed, axle grease flew off and gradually wore the CV joints to nothing. When the axle failed at the track it was a quality unit but improperly prepped. The angle of the axles is greater than stock; however, it's not anywhere the angle on other high performance applications. So, it's probably not hard acceleration but probably the miles and lack of grease over time.

BTW, Boxsters don't have 3.6 engines. Early Boxster Ss had 3.2 engines and newer ones have 3.4.
