XR4ti rear disc with Scorpio calipers

[my8950]

I know this is nothing new.
Since I have a Scorpio for parts, I'm wondering, what rear disc is being used with this setup?
2008-ish Focus?

Thanks!

Also, I'm assuming the Scorpio E-Brake cable will work on the XR with Scorpio rear calipers?

The Scorpio e brake cable is too long you will need to use a 2wd Sierra Cosworth parking brake cable for plug and play fitment.

If you have a Scorpio for parts take it a step further and convert your XR over to 5 lug and also gain the bigger HD bearings from the Scorpio.

The link posted is what I was referencing...

For the rear I think the swap to 5 lug would be ok, but on the front it seems quite painful since struts don't fit, rotors need to be redrilled, what brakes to use. As mentioned, I have the parts and thought to do it, but, not sure it is worth it...I need more info.

Scorpio front calipers and XR front calipers are the same so you can just put the 5 lug fronts right on.
Theres a sleeve out there that lets you put the stock XR strut in the Scorpio knuckle, too. Fairly bolt on friendly.
( Godfrey made the sleeve originally, I think pyropete made some as well ).

If you get this far into it might as well move the Scorpio steering rack (longer tie rods), control arms, and 27.5mm front sway bar over.
Complete rear sub assembly will bolt into an XR also. (Bigger rear swaybar with inboard mounts).

Now you'd have 5 lug, disc brakes all the way around, wider track, and bigger heavy duty bearings and hubs. This is basically the set up on the Sierra Cosworth, except in 4 lug. I have some development pictures of the Cosworth somewhere and its in 5 lug wearing Scorpio wheels - easy to see they were digging in the readily available parts bins.

I did recently see a photo of an XR with a Scorpio rear bar, I was debating to try and use that on my XR, but as mentioned, I would have to make a mount on the arms for the outer connection.

Drop the whole rear beam out of the Scorpio; diff, brakes and all. Then bolt the whole assembly on your XR.

DOWNSIDE: Its a heavy cumbersome thing
UPSIDE: Its only 8 bolts. 2 bolts for the beam, 4 bolts for the diff, 2 bolts at the rear shocks.

Yep, I've done this before with the XR.
I guess my other concern is the width, you stated it is wider, so I'd also possibly have clearance issues with the tires.
The Scorpio I have doesn't have stock wheels, it has some that fit closely, so they are not the right size.

Without knowing the specs on your wheel/tire setup, bear in mind that the XR has a lot more room in the back for larger wheels/tires than it does in the front.

Right, I'm not going crazy with any 10" tire or anything like that. I'd prefer to keep the same on all 4 corners.
205/50/16 is what I'm running now.
I can't have a rubber band tire like many other location due to the roads of Michigan are similar to that of the surface on the moon.

I've run that size-- pretty sure you'll be fine. You're absolutely right, besides the fact that a semi-trailing arm setup goes through camber changes with suspension travel, so rubber bands would probably be reducing your contact patch in that real-world scenario...

I'd prefer to use the spatula wheels even, this is my reason for trying to go with the Scorpio rear calipers.
I guess if I go 5-lug, then I can only use the few available wheels in this pattern.

Hey Mike, your site doesn't tell what year Focus rotor you use on the rear. (I have them in a box, but I'm not sure what year they're from.)

There are TONS of wheels available in 5x112
Audi / VW / Mercedes

Also real easy to convert to Mustang bolt pattern
