Well in that case on the internet you go and find a Genesis at a wreckers in Sydney for me then.:lol:

Thanks Gnome for keeping this debate alive. It's very much of interest to me, especially as I started this thread! Even just having a something that doesn't fit properly in the boot, that you can take if driving long distances, would be great, i.e., you might get away with carrying it for most trips, but if you were driving somewhere 2 or 3 hours away, you'd toss it in the boot with the jack and other gear.

If only Ford Australia would do the work for us. Even if a solution can't be found, a space saver for the back two wheels would be at least a 50% solution! (can the EB space saver fit the back? I thought it could).

I'll buy a spare rim and tyre that will clear the brakes and keep it for long distance / country driving even if it sticks up out of the well. The rest of the time, A custom removable 12' sub will live in the spare well.

Update.

Have tried several guys who make up custom rims and pretty much been told forget getting something made up as a space saver that can clear the brakes. They may exist but to produce from scratch without having an existing wheel that was close and could be modified it would be to hard = very expensive.

But by complete fluke I have found a mate of a mate who works for a Hyundai dealership and he is pursuing the Equus / Genesis space saver path for me, so hopefully something comes back from that angle.

I figure it's this:
"Performance Pack Style Black Wheel - 19x8.5 (15-16 All)"
$164.99

Roof rack sold separately. :bolt:

It is not too hard to get a wheel that will fit over the brakes, but the idea is to get one narrow enough that it will fit in the wheel well as it is not very deep. So a space saver type or the narrowest that will still fit over the brakes is the holy grail in this exercise.

Agree. That said, does that sort of wheel suggested (the GT wheel clone) even fit in terms of diameter in the wheel well? And if it does, how highly does it poke out? I guess you've already had a go with one of the front wheels.

And to confirm, can a front wheel, or rather whatever wheel will fit over the front brakes, be used for any real distance on the back, i.e., used together with the appropriate stock back wheel? I'm no engineer, but I am sort of worried about what the different loading (if any) might do to the LSD.

Thanks for your pioneering work Gnome!! :clap2:

If we put a 265 40 on a front rim as a spare it is only about 25 mm circ difference. Should still clear strut etc and not be too hard on the diff? Or have I stuffed up the calcs

they quote in Aus $ for the 240.42 price. I would get it and maybe have to use a spacer fro the front?

I'm not game to say you stuffed up but I can't understand where you got the 25 mm from. The 40 means 0.4 times the tyre width to get the tyre wall height. If we are using a 265mm in lieu of a 255mm tyre then the wall is 4 mm thicker. Therefore 8mm increased dia. So that would be 8mm less than the rear(275mm) tyre dia. And that's about the difference between a bald and a new tyre. So I don't think the diff would complain too much??

Yep. 8mm diameter but 25 mm circumference. 8mm dia wouldn't be any worse than running a well worn spare on 1 corner of a car. I think the diff would handle it

Forgive my mental block, I read circumference but pictured diameter. You are indeed correct.

Edit: As we do not get the Torsen diff I have removed the reference to it to save confusion.



There are plenty of wheels that will fit if you just want to throw one in the boot for trips, but if you want to keep one permanently in the boot that is a different story.
The front wheel fits in the wheel well but sticks up 85mm higher than the cover.
Rear wheel does not fit in the wheel well at all and needs to sit on top of the cover, so takes up most of the boot, and as it doesn't fit the front to me is a waste of time.

I have plenty of measurements and pics I can post up but work keeps getting in the way of my forum commitments

New avenue I am pursuing is a 7" wide 19" rim, with a 175 - 195 tyre.

I will put up a picture of a 245 / 35 / R19 from my FPV GT that I put on the front when doing this, jeez it looks small in that huge wheel arch.
