I love the ED Sprints, but the AU XR8 has better engine parts and I think more potential when compared witht he spring.
The sprint has GT40 heads and the AU has the newer GT40P's. The manifold, throttle body, MAF, injectors are almost the same.
The AU manual box is the same as the sprint, but the auto is better in the AU. The suspension in the AU is better as well.
The only thing much better in the sprint is the cam, which would account for the 7kw difference. Over the 1/4 mile, I would put my money on the AU but it could go either way, not by much though.
You will be happy with either.
