944 rear brakes

[hot66]

I am using the 20mm thick 944 discs with 968 4 pot brembo's. I will space the calipers out so they sit central over the disc, meaning I will have an extra 2mm gap on each brake pad. I am assuming that as long as I keep the pads & discs in good condition & don't let them wear down excessivly this will be OK.

I know others have done the same as me. IS this OK? Anyone running on the road have any feedback?

Or should I go with the turbo rear discs too? (my front end is using early discs with brembos because the late discs are too big diameter)
