hi need some advice is it possible to fit 2wd sapphire coswroth brakes to a xr4x4 hub with out any modification

mk2grp1

xr is usually 7inch diff cosworth is 7.5
into the hubs they should fit,
but diff side c.v sizes can vary 108mm 110mm so be cautious
check twice , buy once

these are the front hubs i forgot to mention that

No, the front 4 pot brakes found on the 3dr and 2wd Cossies are specific to these models. They won't go straight on the other Sierra models.
I believe you can fit 4x4 Cosworth front brakes straight on a XR4X4.

but i have the the 4pots on a 4x4 hub

Im confused, your question asked if it is possible to fit 2wd front brakes straight on xr4x4 front hubs and im quite sure they wont due to the caliper/disc offset being wrong.

Have you fitted 283mm 2wd front discs as well?

lime

yes they have on 283 mm brakes, the problem is i bought a big brake kit ksport the bracket that came with them which is for a 4x4 stops the calliper from going on correctly, since then i came and started reading and saw that it was not possible to fit 2wd callipers on a 4wd hub i called gary from rs classics and he said it might be a xr4x4 hub so i asked that question to find out if it was possible

fordnut

Ahh, I see. If the big brake kit is for a 4x4 either XR or RS and it doesn't go straight on,
then you must have 2wd front hubs, especially as you have 2wd front brakes.
Also, I cannot see any driveshaft flange sticking out of your hub.
Does your Ksport kit come with calipers and brackets?
It may be possible to machine the brackets to bring the caliper in line with the disc/hub.

lime

yes they come with brackets and callipers , if i machine the bracket it will wrk but will void warranty so I'm trying to figure out if to get a 2wd bracket

fordnut

Im sure you could get some new brackets made using the 4x4 brackets as templates, but changing the relevant dimension to suit your needs.
That way you wouldn't void the warranty. I didn't think Ksport did a kit for the 2wd.

Well I will see what the dealer says he has to email them and ask about it but was more trying to find out what hub I have

lime

I found out about the hubs they are 2wd but some how the 4wd strut fit them
