sorry EDXR8 but i have a couple of questions.
The AU series 1 did not have GT40P's did it? I thought they were introduced for the later model AU XR8's? Same with the throttle body and MAF's.
The XR8 Sprint as far as i knew has a higher spec rated T5?... T50D?
The sprint has has neolathane bushes and big swaybars and i have never been in a stock AU1 xr8 that handles better than a sprint.
Over the 1/4 mile there is absolutely no comparasin. A xr8 sprint 5 speed will murder a 5 speed AU1 XR8 - i do it all the time
I was looking at a AU1 XR8 and a Sprint, i'm glad i chose the latter :)
