I see the Pro4 delrin diff to be all delrin and no aluminum half at all... this should make for a very light, strong and smooth diff.
I have a friend visiting the UK next week.... I've got 3 on hold ready for pick-up at Apex....

Yea, I had the HB diff on my Pro 3 too..but that was to solve the issue with the outdrives as they were slightly longer than the stock ones.
If they are lighter then that is good, I can't really see how they can make the diff smoother as none of the actual delrin touches the balls etc.
Before I get some I'd like to see what they actually look like and what you get, I wonder if the diff is built slightly different?

Is there a reason why we can't use the AE outdrives???

I am going to head to the hardware store and try a couple of other things on Sunday. I will let you all know my findings and hopefully when my new Derlin outdrives arrive from the UK I will do a write up w/pictures on how to do the modification . Rock on!!

GPM
Has anyone used the aluminum GPM front or rear knuckles on the pro 4? They say on the listing that they fit most rs4 cars including the pro 4. When i compared them to the stock knuckles they look slightly different. Hard to tell from pics. Will they still work? Does anyone know?
I will try to post some pics of the gpm's.
