Hi Cliff,
If you determine that the axles are indeed worn, we have them in stock. As Dave said, it's not likey they are worn.
The CV joints have stood up well in our 500hp+ cars, some with over 10,000 miles on them. So if your CVs are pooched then take a close look at the CV Boots to be sure no dirt can get in and the joints have suffient lube.
Also on some applications the factory supplied CV spacer has been left out in Getrag applications. This can cause the joints to wear prematurely. If you need the spacers, those are in stock too.
Of course if you're constantly in "stop light Grand Prix mode" with the car, parts will not last as long either.
What really impresses me about the car is that it accelerates nearly as hard from 100>160mph as it does from 20>80mph. Great stuff!
Cheers
