As always, JHM tests all the products we sell even if we do not make them in house. This rear diff mount is no exception and performs well. We have noticed cleaner and crisper launches, aggressive upshifts and downshifts

In typical JHM style here are 2 videos of some of the abuse we have put the B6-B7 version of this mount through on our in house 2005 B6 S4.

APIKOL Performance Automotive Components is proud to announce the release of its upgraded Rear Differential Mount System for the Audi C5-A6-S6-RS6-allroad and Passat 4Motrion. This Rear Differential Mount takes only 15 to 30 minutes to install. There are 4 bolts and 1 nut involved and it is a straight swap and bolt on part.

It is designed to eliminate excessive rear differential movement and cure the dreaded "clunk" caused by aggressive shifting and/or acceleration. This is a must-have upgrade for higher mileage vehicles as well as anyone looking to increase drivetrain performance.

Material High-strength cast aluminum alloy and custom molded urethane bushings.

Do it
I am doing a refresh on a C5 RS6 with 53,000 miles. I was experiencing some soft throttle response and the typical clunky drivetrain under accel and lifting. I rolled the dice on this rear diff mount as a starting point as I could visibly see the bushing was worn/cracked. I purchased the red (race) stiffness bushing as recommended for the RS6. It was a simple bolt in installation that (on a lift) took longer to round up tools than to actually install. There's no instructions which is fine, but I had trouble finding consistent torque specs. I just ran them down to 28 nm which felt like more than enough. After test driving, I was blown away at the difference that it made. Crisper throttle response and no clunking when working the throttle. Transmission feels crisper when shifting. Definitely recommend this to anyone rocking 20+ year old diff bushings.
