Default Sierra Sapphire 4x4 Cosworth brake upgrade

Looking to upgrade my brakes as currently standard.

Considering Reyland 330mm disc upgrade which is £500

But:

2wd has Focus RS disc, BMW E38 Brembo caliper upgrade, is there anything like that for 4x4?

Mine is late 4x4 Sapphire, running stage 3, 18" Comps, so just want a bit better braking power and looks too.

Has anyone found a good value combination?

I have the 320 mm kit with standard calipers from Reyland. But the only reason I have that is because my wheels didn't provide enough clearance for 4 pots. All 4 pot calipers require at least 5.5 to 6 clearance between the disc surface and the inside of the wheel spokes. But reading you have Comps that's probably not a big problem. So E38 calipers could be an option. But you'll probably need a custom disc. The Focus RS discs don't fit the 4x4 due to the low disc offset on the 4x4.

Could I reignite this thread please...what did you go for in the end...I'm looking at upgrading my 4x4 brakes as its running about 380bhp on standard set up so I want to stop better�� before I look for more power...What calipers did you go for in the end?..
I have 17" rs7 wheels so guess that will be a factor as to what will fit...although lattice are currently on for winter but New brakes will mean these won't fit which won't be a problem...

Any suggestions for 4x4's
Good friends have e38 brembos fitted and focus discs but they are 2wd so discs would be a problem on mine ??

Any help greatly received!

Many Thanks
Stu.

I don't think RS7's will give enough clearance for 4 pot calipers.
