034 Motorsport offers replacement mounts in two "densities"..... Street Density is 25% stiffer than OEM, while Track Density is 90%. They're marketed as a complete kit ($300), or the dogbone ($65) and engine/trans mounts ($235) can be purchased seperately.

I installed all three pieces, a complete Street Density kit, in my 2001 225 Quattro Coupe. My original mounts had accumulated 160k+ miles but still seemed Ok. I'd somehow avoided the clearance problem with the 42DD 3" DP and stock mounts that most experience.

day 1: a late start, an oil change and alignment work left time to complete only the dog bone... by itself it tilted the engine forward, and now my down pipe hit the chassis under high power.

day 2: the engine and trans mounts were added and all's good... DP to chassis contact is gone.

pluses:

NVH? nope! there's no new noise or vibration...
the car's a bit smoother in fact

shifting is improved...
A recent upgrade of my original DieselGeek short shifter to a Sigma Six increased gear change effort substantially. Cold (winter) "drive off" required a pretty lengthy run (20-30 minutes) for things to warm and loosen up.
Now, no warm up's needed, the gear box is "like buttah" :-)

overall, the car's just more "hooked up"

minuses: none

bottom line: this kit works as advertised!

"STREETDENSITY Mounts are solid rubber mounts with a 50 durometer about 25% stiffer than stock, this means they still ride smooth and quiet but provide a marked improvement in drivetrain dampening over stock mounts"



for day to day, road trips, canyon racing and occasional tracking: 034 Street Density engine mounts get two thumbs up from this reviewer!


ps: props to John for working through the details and for a test drive


edit: the dog bone has 3 bushings. All three in my 034 street density bone failed within the first year. The engine and trans mounts continue to work well. Pass on the 034 dog bone. Most use poly successfully... I'm currently using OEM with a mod to the bone increasing preload on the rubber bushings... result: poly stiffness with zero noise transmission<ul><li><a href="http://www.034motorsport.com/product_info.php?products_id=13092{6}230">034 Density Line</a></li></ul>

 

Glad to hear it all installed smoothly. Will be interested to see if your motor mount drains itself

 

Upcoming VF Engineering vs. 034 Street Density test......... : )

 

before Shackfest, and kept the VF tranny mount. Put my stock dogbone with Energy poly insert back in too. So the only VF is the tranny.

Vibration has been eliminated.

 

have these? aren't stock pieces adaquate enough as it?

 

the desire to freshen up my high milage OEMs, and price...

I didn't check, but rumor has it that 034's are cheaper than new OEMs :-)

 

there, i'll swap it out. 2 out of 3 parts are easy to swap, the one under the dam coolant resovior is a PITA, do you agreed to that statement?

 

I just go into mental "auto pilot" and slog thru jobs like this...

on balance, it's not that bad

 

... yeah .. any specific tq setting or just tighten till it's tight?

 

Heh! a motor mount shoot out!
