996 brakes on '98 Boxster

[Amdoor]

I have a '98 Boxster and have acquired a set of 996 calipers. The fronts are no problem as the discs and pad part numbers are the same for the early Boxster S and the 996. The part numbers for the rear of an early Boxster S and the rear of the 996 are different for both the pads and rotors.

The information that I can find shows the same rear pads for both the Boxster and Boxster S. I thought that the Boxster S used the same rear calipers as a 996.

Have any of you upgraded an early Boxster to the 996 rear calipers?

Can I use the 996 rear calipers on my '98 Boxster? Which pads and rotors should I use?

This is going to be a bit more complicated than expected; yes , the fronts are a bolt on, but the rears are anything but. The S Boxster used different suspension carriers in the rear, and a completely different size emergency brake set up, mostly sourced from the 996 cars. As the result, the rear 996/S rotors will not work without all new suspension carrier hubs and emergency brake hardware, which can be very expensive to source unless you pull it out of a wreck. This is why people put the red S brakes on the front and call it a day..........

Thanks JFP. That information is a big help. I'll just put the rear calipers on the shelf or use then for paper weights or door stops. I should have joined the forum before I bought the parts. Thanks for your help.
