What recommendation do you guys have for a daily driver I don't want vibration could deal with slight idle noise I guess I did white line rsfbs already didn't do the diff bushings but my mechanic said my motor mounts are shot so i need to replace would like to try am upgrade should I use two right is mounts ?

You know, I was wondering if someone wanted to step up and do this, perhaps @A4RingedONE8T would be interested, credits to vtl for doing this originally, but he said he had no time to produce them. I wonder if this would be a good middle ground between the ADE mounts and the 034 mounts in terms of stiffness and reliability.

I haven't run the 034's but I run the BFI's (which are original design of the Turners). The 034's are just stock mounts with a solid poly inside instead of the fluid filled rubber in stock mounts. I have the stage 2 BFI mounts and they're so much better than the stock ones and the best part is they are rebuildable.

How much stiffer than the 034 are they?

60 durometer is like stock. I have the 80 durometer and I have no nvh
I had quite a bit of vibration with the stage 1 BFI mounts, especially at idle w/ AC on. Granted, I have an AT.

Had to swap out the pass side one too with a 335is mount, since it started to melt due to the heat from the dp.

What does the bottom cap coming off mean for performance?

I don't really know how these things work, but assuming the center is just a hunk of poly, that means there is nothing restricting the travel of the motor mount, so I'd suspect it would just lead to a squishy feeling and poor performance.

So what exactly do you need/asking to have made? I'm completely lost? lol

Running these mounts for the last 2000KM. so far so good although the failure rate worries me.
