xdwagooon 46 Posted November 14, 2013 ok so quick question, I have an au xr8 solid axle diff and need something beefier for my ltd so was hoping to fit that as its lsd etc etc wondering other than the obvious handbrake, brake line, bushings, tailshaft yoke etc will it fit? being different offset is it longer etc? im out at ste and cant measure it so thought id ask those in the know Share this post Link to post Share on other sites
n00bus m@x1mus 465 Posted November 14, 2013 Yes it is longer and you might just squeeze it under there if you have 6" rims but generally are going to have to run Post AU or +38 offset rims. A mate fitted an AU diff under his XH with EL GT rims that are 17x8s but the offsett favoured it... just!!! Share this post Link to post Share on other sites
xdwagooon 46 Posted November 14, 2013 ive got a heap of au and ba rims laying around anyway and its pretty much just a skid car so that should work well... cheers Share this post Link to post Share on other sites
SLO247 1,713 Posted November 14, 2013 AU XR8s all had IRS just so you know. Share this post Link to post Share on other sites
bear351c 10,273 Posted November 14, 2013 Good point Dan. You sure about the XR8 diff? Did it come out of a V8 ute or wagon with leaf springs? Share this post Link to post Share on other sites
n00bus m@x1mus 465 Posted November 14, 2013 Utes didnt. And he states solid axle so im guessing its a ute rear. Share this post Link to post Share on other sites
xdwagooon 46 Posted November 15, 2013 its definitely coil sprung solid, pretty sure series 1 still came out solid didn't they? either way its lsd etc the guy still had the motor and everything there but it was just a wreck he bought and scrapped Share this post Link to post Share on other sites
xdwagooon 46 Posted November 15, 2013 I could be wrong but haha either way ive got a spool and gears to go in it if need be Share this post Link to post Share on other sites
SLO247 1,713 Posted November 15, 2013 All sedan XR8, XR6 VCT and Ghia/LTD IRS. Is it an LSD? They were an option even on the XR6. Share this post Link to post Share on other sites
n00bus m@x1mus 465 Posted November 15, 2013 Ive seen a few series 1 AU XR6s and XR8s with live axles. Series II was IRS from base model, it would have to have LSD if its a tickford car, wouldnt make sense not to. Either way it will fit no probs, its just the wheel offset thats changed, the rest is pretty much the same as EF/EL just the wattslink pivot changed and they have a couple extra holes in the top control arm brackets.

Ants 6,370 Posted November 15, 2013 I've never seen an au xr6 without lsd, it was an option on ba. Lsd was stock on au xr's.all the hp xr6 sedans were live axle, all the xr8 and vct xr6 sedans were irs no matter what series.<br /> Share this post Link to post Share on other sites
SLO247 1,713 Posted November 15, 2013 My bad, got confused with BA. Weird how everyone thinks early AUs are so different. The differences are mostly cosmetic. Like Noobus says though it will fit. Share this post Link to post Share on other sites
Ants 6,370 Posted November 15, 2013 S1 au has smaller front brakes and a different steering rack, that is the main mechanical difference. Share this post Link to post Share on other sites
n00bus m@x1mus 465 Posted November 15, 2013 Different front spindles as they ran the same rotors and calipers as EF/EL, and ive been told because of this you cant upgrade the spindles without upgrading the K frame aswell because the bottom arms dont interchange... so ive been told, never tried it myself.

Ants 6,370 Posted November 15, 2013 Yeah au2 to bf3 run the same front end, can't say I've tried to do the upgrade either so couldn't say if the k frame is the same or not.<br /> Share this post Link to post Share on other sites
n00bus m@x1mus 465 Posted November 15, 2013 Apparently it in the front lower bush and the ball joint pin is on a different angle so the new spindles dont fit the arms and thr arms cant be swapped without the k frame aswell. And sorry poor choice of words before.. au series I rotors are same diametre as ef/el and cant be upgraded for larger discs because of the spindle design. 1 Grimmy reacted to this Share this post Link to post Share on other sites
