Boxster Brakes, Which to get? S or Non S? Options

[soloracer]

I am looking for a decent brake solution for my 914. Currently the car has an 80's 911 front suspension and I purchased a set of 964 C2 calipers and Carrera rotors. I thought I was doing good until I saw the bolt spacing for the 964 calipers don't match the strut mounts. I found adapters but they require sawing the mounting tabs off the calipers and buying an adapter - to the tune of $1000+. So now I am considering selling the 964 calipers and going with a full set of Boxster units. Question is though, which ones do you go with? The Boxster S or non S? Or should I just scrap the idea of Boxster brakes all together and get 993's or something else? Maybe keep the 964's and redrill the holes? Know anyone who does that sort of work?

Any and all suggestions are appreciated.

are you sure your struts/spindles are off of an 80s 911? they should be 3.5 spacing, just like the C2 brakes.
or is your problem getting the caliper to center on your rotor? You may have to go to another Porsche rotor. I know when we did a "big black" up grade to a C2 a while back we needed an adaptor to get the big blacks mounted (they mount radially instead of axially like the C2 stock brakes) and we also had to use 928 S4 rotors to work correctly with the calipers.
