Porsche 6 piston calipers

[stumpy67]

Hi

I'm upgrading the front brakes on my B5 RS4, to the above.
I've had the discs (new) milled down to 355mm dia, and was getting them fitted next week along with the new calipers/pads, but have been let down.

Have also heard the calipers need machining down too. Anyone know what this is, and where I might be able to get sorted in Kent ??

Thanks

I'm sure that you've got it scoped out, but you have ascertained that the calipers fit the uprights, and that the disc offset fits the calipers?
Why the need to reduce the discs' OD?
