I do. The biggest hassle is getting access from above. If I remember correctly you have to pull the airbox assembly and battery. Not hard, just fiddly.

Then I believe a pried/levered the engine/trans assembly to the right just a tad to be able to slide the mount in and out. I must have had a floor
jack underneath the transmission.

 

I have been playing with mounts since I began my build in January. My car is roughly 400hp, a good candidate to test the mounts survivability.

I found the GP3 upper mount with Powerflex inserts + OEM transmission mount with Powerflex insert is the best combination so far. It is resilient and takes the abuse without bursting or collapsing. But ALL THREE mounts must be on a similar level for survival and performance to be good. What I mean by this is:

A. If you did your upper motor mount without correcting the dogbone or the transmission mount (which can be gotten to without doing crazy work), it will fail prematurely.

B. Even if the dogbone and upper mount are new and good, a shot tranny mount will allow way more vibration and movement than you want and will accelerate the wear on the other two.

C. Doing the tranny mount is not impossible. It requires loosening/removing the upper mount bolts, connecting the engine to an engine support up top and pulling and/or lowering the transmission position out of the way of the mount.

Using the GP3 mounts (upper engine & tranny) is an option for those who don't want additional stiffness. I used the OEM tranny mount b/c it was stiffer with the inserts for one and the GP3 is beefier and the Powerflex mount insert didn't work there. The brand new GP3 transmission mount is still in the box and for sale if anyone wants it since I went in the direction I did.

 

Hi
you want sale 22316886197?

 

Yes DM me

 

I was quoted $1200 by MINI to replace. Replaced it myself while upgrading my intercooler for $40.

 

Great, would you do it for me too? I'll pay you. Where are you located? Anybody has someone to recommend for this job in NY area that already did it and has the tools?

 

Sorry fren. I moved to Florida from New York 2 years ago.

 

Update we have aftermarket/oem for https://www.ecstuning.com/Search/Sit...h/22116886196/ GP3 mount

And

Aftermarket
22118835566

https://www.ecstuning.com/b-bremmen-...2118743621~om/
https://www.ecstuning.com/b-assemble...22118743621kt/

 

Are these just more heavy duty mounts than the standard Cooper S?

 

The 22116886196 is the newer revision GP3/JCW parts stock maker aka OEM so you save some $$$. If you want to use that version of the mount.
The aftermarket bremmen parts 22118835566 is a money saver /newer revision of the stock Cooper S part. If you want to use that version of the mount.

https://www.ecstuning.com/b-powerfle...pff5-1321~pfx/ works with both as prevention/helper.

I know most people have the older versions and might want to do these and then get the little yellow dog bone polys at the same time.

Hope that helps.

 

Uhhhh

Current BMW GP3 part (and the one discussed upthread) is 22118835574, which itself is listed as a supersession of 22116886196. Now, I have absolutely no clue what the difference is between them (do you? would love to know), but heads-up

 

Nope, but i do see that little white SK sticker on the Lemforder one, but the next one that comes in could match the white SK sticker of 22118835574 MINI part.

 

Where? I am in Miami!

 

For the record, I have the latest GP3 upper mount with the Powerflex inserts and been hammering it with a 400hp B48 motor, still good to go and even after the CRAZY heat we saw a couple months ago where night temps were as high as 110+

If I plant the pedal and lift mid-boost the engine and tranny still trash a bit but gains composure fast also. I think once Direnza finishes the redesign of its more solid mounts I will end up using them given the power levels I am running/plan to run

 

How is it holding up so far?
