Peter had the same setup in one car and he said it was fine. First gear was great for at least 10 meters (!!) in drags, but he still managed 12 secs. But that is his driving ability! It is perhaps not only the rear end, but the ratio of the US Mustang T5 first gear. The Aust T5 has a better ratio for first I am told. It could be interesting to consider swapping the Mustang first (3.35) with the Aust one (2.85 ?). For the moment I will be happy when I get it back and see how it goes. I was quite happy with the current rear end before.
