hey guys. Looking at getting new diff gears for the XT. I'm looking a set of 4.11's (not fussed about fuel economy as it's a weekend car). What size is the XT diff (9" ?) and how many spline?

Cheers in advance

AFAIK, OED666 on boostedfalcon has a set of 0578 4.10 gears, not the dodgy Pintara stuff.

Same different, different ratio. XR6T, XR8 and FPV get a Dana 86.

Not sure if they are same diff or not. All I know is the XR range and FPV have a higher ratio so they are slightly more aggressive off the line compared to the XT (though I still flog XR6's lol)

I don't want a turbo at the moment. I want a quick N/A BA 6. Maybe later on down the track I'll go forced induction, when I have the $$ that is, and the license.
