Got AKG diff/subframe bushings. Anyone else have them?

daumas · Sat, Feb-04-2012, 04:07:01 AM

Just got my car back after subframe reinforcement, a 3.91 gear change, and AKG diff/subframe bushings put on. Needless to say my rear end is very solid now. SMG gear changes are crazy fast and crazy hard. The only problem is that I have quite a bit of gear whine at almost any speed over 30mph. The sound can be overpowering even with the radio on when driving on 70mph roads for 30 minutes. When I slow down the noise reminds me of the a fire truck siren.

My shop did warn me about gear whine, but I was not expecting this. Before I go back to my shop and talk to them I was wondering if anyone had experience with AKG bushings and could share your experiences.

I DD the M, but I am planning on about 4 HPDE events this year as to why I got all the work done in the first place.

Yes, on my shops recommendation. I asked, before the install, if they would be quiet enough for daily driving. They thought they should be.

I don't have a problem with road noise or feel. It's just the diff noise.

Ya I have those shitty powerflex yellows and just bought solid diff from vac and am buying the 75d from akg. That's strange that it would be that loud. Akg just came out with 75d diff like just days ago. I'm probably going to buy both diff and sub now but will try solid first is there a way you could get me a sound clip of that.

I have stock diff bushings and AKG 90A subframe bushings. The whine isn't that bad, although I don't have rear seats in place and I also have a mason rear bar that connects down to the diff which makes it even worse for me.
