Default Who I still running a 6" rear with 10+psi?

I'm probably going to upgrade before mine breaks to help pay for the 7" swap, but just wondering.

Still running mine with about 10-11 psi. I autocross the car but am careful especially with 1-2 shifts. I've only been running my setup for a couple of months though.

I've known people running 15psi FM II setups on the 6" rears for years and have no troubles. Mechanical empathy goes a long way I suppose.

I'm not sure why you would think that 10PSI will break it. I run 15 PSI in mine with no problems. Of course, I've totally trashed rear ends with NA cars - it is all in how you treat them.

I'm still running the 6" rear. Next week the LSD 7" goes in. No problems yet on the 6", just leary.

Yeah I'm not hard on it really, never clutch drop it, shift into 2nd kinda hard sometimes at autox, but what I mainly want it for is to swap in an RX7 LSD. My VLSD is gettin me down. Ruins all my fun.

no you need to swap the whole pumpkin halfshafts and drive shaft to have it all work.

what he said. The weak link in the 6" is the ring and pinion, and you'll need all that magnamx-5 listed to go to 7"
