I'm going to get new rotors shortly and around the same time I'm looking for new wheels. Now everyone knows that AU onwards wheels don't fit the E series falcons, but what about if I get AU discs. Will they fit my EF ? If this works I should be able to bolt AU wheels straight on yeah ? It seems there's alot more AU wheels around for sale (and cheaper) than those for the E series.
There would be no way in hell that you could put AU rotors on en EF. Not unless you change the front suspension setup on your EF. The AU have a "hat" type rotor while the E-series have bearings and all in the rotor hanging off a spindle.
Hyena, there is no point of putting au rotors on a ef/el.
Bremco Brake Packages are $2000 with twin pot calipers, otherwise you can get twin pot calipers from the ELGT (but you will need a few other bits and pieces, control arm etc to suite)
Easiest way and seems to be the go for 99% of the people with modified ef/els is to get DBA Crossdrilled Slotted or Slotted Rotors.
You can find these on www.discpads.com very cheap, otherwise your local auto store that sell rotors etc.
Fronts are $166ea (ABS) and rears are $137 (ABS) [crossdrilled slotted]. Slotted are cheaper by i think 20-40 on each rotor.
fUSiON, Hyena's point is that he would like to be able to choose wheels that are available for AU offset rather than the more limited pre-AU offset.
I reckon it is well worth asking Hyena - I like that at least some of us think outside the square.
Will AU rotors go on an EF/L upright - nope, as explained above.
BUT......could it be possible to bolt a complete AU upright/rotor/brake assembly into an EF/L? Maybe!
I know the upper ball joint moved from the upright in the EF/L to the upper-arm in the AU so you would need to swap over the upper-arm as well. For fun Ford also changed the mounts of the upper-arm to body-structure but these all still bolt on at (I'm pretty sure) the same four bolt holes each side.
What I don't know is whether the lower-balljoint is the same unit and orientation, the distance between left & right ball joints is the same and whether the steering rack pick-up on the upright is in the same location and uses the same tie-rod ends. There is also the matter of swaybar - does it mount the same and brake lines but the last two points could be overcome with a bit of effort.
So, who has access to an E-series car and an AU and is handy with a tape measure and parts catalogue ?
Both the "K-Frames" for the E series and AU's are different. This is what I think you are refering to Raptor as the lower ball joints. I've got access to both E series and AU's and can honestley say that there would need to be a serious change in front suspension parts, and would possibly costly. If any one wants to try it, go for, these are just my 2c
No, I am referring to the lower balljoints in my post above. Speculating on whether a suspension upright (spindle, stub axle whatever you want to call it) transplant could be possible.
I have no doubt at all that a complete AU front suspension subassembly (including alloy crossmember etc.) could replace an E-series 'K-frame' though some fabrication would be required as they connect to the chassis rails slightly differently. As you say maco65, some "...serious change in front suspension parts...".
Though if it was a complete retrotech rebuild proposition that is exactly what I would do. Instant upgrade in suspension/brakes/steering/engine and access to AU wheels. Plenty more involved than just the handware transplant though; plumbing (fuel/brake/aircond/steering) and wiring.
It's gotta make some sense, that's how they put them together at the factory!
It could be possible to tranfer that, ahvn't exactly studied how the lower ball joints and sway bar... all join up compared to between the E series an AU.
I wasn't specifically after the AU brakes, I just thought that if I'm going do get new rotors anyway it'd be an added bonus if AU wheels fitted. I'll have the front suspension semi-dismantled to put in the new shocks and springs soon but it sounds like it's going in the too hard basket.
Changing the front suspension won't change the wheel offset difference between el & au. Try looking into having spacers made to go behind au wheels, I have seen this done to xh utes & eb sedans. Wheel stud patterns & hub diameters are the same for all models.
