So I did a rear brake upgrade on my s14 a while ago. I fitted r33 Gtst rear brake assy. The RH rica is pushing the backing plate into the rotor. Never noticed it till the other day when I jacked up and the wheel didn't spin freely. I thought it was the handbrake dragging at first. So I removed the wheel, and rotor moved freely. Worked out it was the rlca pushing against the backing plate when the wheel was bolted up.

Anyone done this upgrade and had the same problem? I've checked the balljoints for play but they are still good. Only happens on Rh side although I can see a mark on Lh side when it has rubbed.

That's weird, the backing plate position is the same as your s14, so that means your s14 backing plate would have been rubbing as well?

I looked at that and it wasn't rubbing on the originals. On the old ones the backing plate indents a bit to give more clearance. And can do so because the rotor is so much thinner

can the backing plates be swapped? might be on the wrong side?

i have no issues with my 180sx w/ R33 rear brake assembly on the 180 RLCA

No rubbing issues on mine, same as Varvs; R33 GTST rear brakes/hubs on a 180sx using the S13 subframe. I can't remember if I cut off the lip that covers the side of the rotor for the rears, definitely had to do that to the front which was using an S15 plate, but that's not your issue anyway.

Can you post some pictures of the issue?

There's a picture, the rear does need a wheel alignment because it does have a lot of toe out for some reason. Not sure about camber specs but looks alright. Not sure if this would fix it though, and don't want to run heaps of camber in the rear

Also would anyone know the stock length for traction rods in a s14?

From what I saved off an old traction rod thread on the nissan road racing forum - Stock = 8.25" / 209mm bolt to bolt.

No cracks in the knuckles, everything looks good I don't know why it's touching

Ok guys worked out the the knuckle is bent. Must have it a gutter at some stage. Anyone know if s15 rear knuckles are the same. I'm guessing they are...
