Anything else to do while getting the serp belt done? [S4]

B6/7 S4/RS4

Well I just got the car back and wow does it stop and go much better. The LWCP is just another little thing that makes the car rev a little faster. Replacing snub, motor and rear diff mounts has eliminated all kinds of thunks and most importantly gained smoother shifts.

Finally got the winters off and the BBS RC/Super Sports on. Comparison for kicks:

  • 18" Avus + Falken FK452 tyre = 23.3 kg / 51.3 lbs
  • 17" BBS RC + Michelin Super Sport = 19.1 kg / 42.1 lbs

So about a 9 lb per corner saving, which is what a pair of JHM LW rotors would save me at the front, so I’m pretty pleased as I’ve achieved weight reductions yet kept something a little OEM (the RC’s came with the C5 A6 2.7T Sport package I believe). Might look better with spacers. Quick pic at the park:

The 18" Avus didn’t go to waste. Quite the opposite. I think they look much more at home on the C4 S4!

the avus wheels look great on that beast

RS4 doesn’t have a snub mount. I’d love to tighten it up because there’s a bit of drivetrain clunk on shifts and when engaging the clutch once in a whlie. Wonder what is do-able.

When the C4 S4 became the C4 S6 (1995 I think), 17" Avus became stock. The stock wheels for the 1994 S4 are the 16" Fuchs - which weigh 18.5 kg with my Hankook iPike winters. They are forged IIRC.

What is there instead of the snub mount for the RS4? Just motor mounts? Why not replace those.

I know they’re “just mounts” but they’ve made the car another level of fun to drive. The car somehow feels new.

Its called a torque mount, instead of compressing between the motor and core support its like a third motor mount

Didn’t koolaide use hockey pucks to fix his broke torque mount

#26

yup, its a good temp fix since it helps when the motor rocks down, but it doesnt do any dampening when the front of the motor rocks up
