I have an 02 series 3 AU Falcon XR6, looking at changing the diff but don't know which way to go, or what the best set up would be for the mods I've already had done. I don't take the car on the track, it's a daily driver, just wanting to build up a nice street car. Any suggestions would be great.

cars specs:
− CMS Stage 3 head with 2a cam - Includes reground cam, vernier cam gear, full head service, new valve guides, heavy duty valve springs, oversize exhaust valves, minor porting carried out.
− 2 1/2inch redback mandrel bent sports exhaust
− redback extractors
− ballistic stainless steel high flow cat
− K&N panel air filter
− lowered on Pedders Sports Ryder springs 2inches in the rear and 1.5inches up front
− Pedders Sports Ryder shocks
− NGK Iridium IX spark plugs
− custom flash tune
− transmission cooler

are we talking ratios, i assume these have 3.45's like the earlier EF EL XR's?

4.11 LSD

im not sure if its already got LSD?

should do being an xr6

sorry guys, should have mentioned it does not ready have lsd

an LSD was a priced option on AU XR6 HP, and then all BA onwards XR6's
