I wanted to know if I need to order loaded NX rear calipers to run the NX rear discs (258mmx9mm vs. 234mmx7mm) or can I just order the caliper? I wasn't sure if I needed the carrier like the one needed to run the NX front calipers.

Thanks,

Don't bother. The rear brakes have such a light load they don't need upgrading. I have 80k miles and 8 years on my ORIGINAL rear pads that have seen 5 track days and several dozen autocrosses. They still have another 80k miles left on them.

If you want looks, then fine, but don't do it for a non-existent performance increase. If you do it anyway, you'll probably need the NX proportioning valve.

Thanks for the advice. My rear calipers need some serious help so I was just going to replace them. I will stick with stock then, the parts are much cheaper.
