LoneStarS30Z Posted May 15, 2011 Share Posted May 15, 2011 Ordered the R4S, part number AP137 and they are not long enough for the pins that hold the pads in place to be inserted. WTF? Even on Porterfield's website it says "ommon brake pads for 240,260,280Z Upgrade". Clearly there's a mistake on their part, or mine. Worst part of it is that the invoice is stamped with non-refundable markings all over it. So great. I have a set of $80 useless pads. Any ideas on what's the right part number?

310z Posted May 15, 2011 Share Posted May 15, 2011 I have Toyota 4x4 four piston set up from MSA along with their rear disk conversion. I just put on a set of Porterfield R4-S all around. The part number for the front is AP 410 and the rear is AP 230/323. They have much better feel and initial bite than the stock Toyota pads in front and Nissan in rear.

LoneStarS30Z Posted May 15, 2011 Author Share Posted May 15, 2011 (edited) Yes I have the upgrade, it was installed when I bought the car a year ago. I was lead to believe it was the solid set up, but now I'm starting to feel like a dumb dumb and think I actually have the vented calipers. Edit: Do'h!!! After seeing this image: I now know that I have vented calipers. PO did not mention this, but ultimately my mistake for not knowing the difference. On the flip side, I have a set of brand new front R4S brake pads for sale! Edited May 15, 2011 by LoneStarS30Z Quote Link to comment Share on other sites More sharing options...
Dlirium Posted August 26, 2015 Share Posted August 26, 2015 I have Toyota 4x4 four piston set up from MSA along with their rear disk conversion. I just put on a set of Porterfield R4-S all around. The part number for the front is AP 410 and the rear is AP 230/323. They have much better feel and initial bite than the stock Toyota pads in front and Nissan in rear. My understanding is that the rear kit from MSA is based on a '90-94 Nissan 240sx (S13) rear calipers - that seems to indicate a Porterfield AP272. Are those the calipers you have?
