urs4 brakes

[audinut]

are urs4 front calipers/carriers the same as an S2?

[djh]

no and there are two different versions of urs4 brakes.

u.f.o's (they look like ufo's thru the wheel) - these are not the best and cost the earth to replace
hp2's - these are the one's to have and same as whats on s8's iirc

Anyone with a spare hp2 setup??? I hate the ufos!!!!

[Hammu]

I have one set of HP2 Calipers, i can also do the machining modification for UFO strut.

[Drummer87]

What needs modified ?? Then what callipers and rotors will they hold

[Hammu]

Grinding about ~4mm from HP2 carrier so it will center to right place with ufo strut and HP2 rotor.

Yes, you have to bore the caliper fastening holes bigger, and use bigger bolts. The thread is on the caliper not on the strut anymore.
