LOL - Got it. Do the upgrade...for the money, it is the best you can do! The Boxster Cup racers are using the same calipers and rotors plus have roughly 500-700 lbs on a full interior 914. I had a G Class PCA racer - phenomenal car (one I should have kept!) and it was mind blowing how good the brakes were (granted, ABS + Power make a world of difference) were. Good luck and reach out to me if you every need any help - I probably won't know the answer but I know who will!

Is this a trick question? I could be wrong but they shouldn't need an adapter - they should bolt right up. I ran a set a decade ago (at least by memory)...plug and play.

DUH! Stupid me...that is correct. I was equated his 2.5" mounts to 3" - needed another cup of coffee this morning! (IMG:style_emoticons/default/blink.gif)

I did a front and rear boxter caliper conversion a few years ago. I used some early 911 struts with 3" spacing. I made my own mounts and had to do some machining on the struts to make them work and the thread is somewhere on here. I love the brakes as they are very powerful. I ran a 19mm master cylinder at first but put on a 23mm later. I tend to like the feel with the 19 better as it takes less effort on the foot but has more pedal travel. My rims are 15" deep 6s with hearts and the fit and I left the stock valve on for the rears.
