Is your backbox to your rear Diff?



You can sort of see marks, and it's shiney in the "flesh" where it's bumped a few times:



If I wiggle the backbox I can make it hit the diff, surely this isn't right?

It's a prodrive backbox so not a cheapass aftermarket job - the rest of the system seems lined up perfectly and the tailpipe sits in the recess spot on.

Maybe some stiffer hangars will stop side to side movement, but I was surprised to see this gap when I looked.

 

Ttt, anyone willing to stick their head under for a look?

 

Heres mine, with a Japspeed exhaust.. no where near rubbing. I cant wobble it near either

Cheers mate, loads of clearance there. Mine doesn't have much sideways movement but just enough to clip the diff.

I'm pretty sure it's a rare occurrence, the metal is slightly shiney from impact but no dents to be seen. I just thought it was a bit odd from a backbox which is pretty much OEM! (Prodrive).

It sits right in the recess, so without altering the tubing I'm not sure what else could be done with it. Possibly poly mounts to completely rule out sideways movement.

 

Ad say maybe the rubber mounts are perished letting it move. Poly bush like you say. For the coppers they cost. You have lost nothing by trying it.
