B5 S4 calipers onto gt tdi (lucas hp2)

[Marc2204]

Hi guys. I have a set of lucas hp2 calipers sitting about from when I had an a4. They came from a V reg audi S4 b5.

I think I'm right saying the B5 rs4 calipers are the same as the r32/s3..

Wondering if the lucas hp2 are a direct fit onto the mk5 platform?
Cheers
