    Stern & Apikol mounts

    Looking to confirm model numbers and place of purchase for any owners that are running Stern Motor Mounts, Apikol Tranny Mounts, and Apikol Differential mounts. In enquiring about the Stern mounts through a trio of on-line vendors/resellers, I was not successful in guaranteeing a specific model number as STern doesn't list any specific for RS6. I know a few members are running them and wanted to confirm the model # you purchased as there are different heights.

    Thx

    Bought these for my RS6 and loved them. Come with the sensor deletes as well.

    Same link on the engine mounts as Corbett posted above. I went with the soft. At idle there is a little vibration felt that goes away if you bump up the RPM's by a couple of hundred. I also have the Apikol tranny and Diff mounts. Had the Diff mount in there a year before the other mounts and no change felt but I'm sure the stock rubber mount was getting soft. The Apikol tranny mounts at the same time as the Stearns motor mounts so the combo probably causes the little vibration at low idle but other than that no noticeable changes other than the drivetrain slop seems to be reduced. I would definitely do them again and when I go to the 6spd conversion this summer I'm sure the lower drivetrain slop will be even more important then.

    I dunno if there's a way you can tell apart from a visual inspection for cracks/wear, but rubber ages over time and our cars aren't getting any younger.

    I had the blue Apikol Diff Mount as I had a bit of driveline lash.
    Installed in 15 minutes.
    Noticeable decrease in lash, not completely eliminated but definitely reduced.

    Upon inspecting the OEM Diff Mount, the was 1 of the rubber prongs cracked in half completely; then another prong was on its way to being severed also.
    Upon inspecting Wade's (born2be) OEM Diff Mount, 3 of the rubber prongs were cracked completely and were on the way to total failure.

    Sterns all the way and Apikol all the way.

    Not sure about the Apikol Red Diff Mount.

    Are you going to stop and say hi to Mike at PureMS?
    What about that dentist fellow named John (Audi5000csqt)?

    It isn't often that So Cal receives someone from "Cowtown, AB"...

    I hadn't planned to drop by no. It's a whirlwind visit as it stands already.

    And just to clarify for those that aren't knowledgable about The Greatest Outdoor Show on Earth, Cowtown is merely slang for Calgary, Alberta. The Oil & Gas hub of Canada. Bigger in natural resources than Houston/Dallas if I'm not mistaken. There are more cars per capita here than any other city/metropolitan in north america. Every possible type of car that you can think of (including ubber expensive hyper cars) all exist in this city (Pagani, Bugatti, Maseratti, etc.)...

    Did you get all these in yet? Can you give us a quick review on harshness and noise? Are the Stern mounts a good fit? I remember reading that they might be too tall. My drivetrain with the 6 speed is sloppy as hell but I want the car to be smooth and quiet so i'm concerned about the mounts being too stiff.

    I have two suitcases full of parts waiting anxiously to be installed yes. I have been swamped with some summer home renovations and haven't spent any time at all working on replacing everything on the winter ride. I added a new set of rotors to all the other items along with a new set of wheel bearings also. Going to be like new - so to speak. lol Can tell you more closer to start of September.

    I've got the Stearn and Apikol (Softer) mounts. A little vibration at idle but gone at just above idle and beyond. Don't notice any harshness with it and I'm sure there is less drivetrain play (also have the Apikol rear Diff mount) but I've had the combo for 3+ years so I can't remember what a regular RS6 is like. I'd do it again over stock. Sure I wish the slight engine vibration wasn't there at idle but I'd do them all over again.

    Anyone use these over Stern? They look like they'd be easier to install with the bolts instead of studs. Also they are available with 10mm hardware instead of the factory 8mm FWIW

    Not suitable for street use. They are rigid mounts with zero dampening. Drag/off-road use only IMO.

    They are isolated with rubber. They look like they are rigid but they are not. They have a street and a race version.
