Naw, it's not the T5..it works great, smooth and it really makes driving a hoot. The bone stock little 235 with 29" tires and a .72 OD scoots around town with ease in 4th gear. It's when you get out on the highway @ 65mph and shift it into 5th and the RPM's drop back to 1670. It's way to tall a gear (3.08) for even the flatland. Being that I want to cruise at 65-70 mph I should have gone with the 3.42 or maybe even a 3.73. Also noted that my oil pressure at the lower RPM was suffering a bit.
Maybe it was just the fickle-finger-of-fate or the posi/discs that attracted me to this obvious "automatic" diff but it's time to bite the bullet and start scouting up a 3.42. Probably won't be able to find one with discs, which incidently are awesome (non-power) but you never know!
I guess what I'm trying to say is that if you're contemplating a diff for your 235/T5 combo you might be wise to stay away from the tall stuff and give the 235 a little extra RPM's to be happy.
I hope this helps someone avoid the problems I've created for myself.
