Well I recently got my hands on the new BSH Track version of the lower motor mount. Let me say ditch those powerflex bushings right now. Its a complete replacement for the motor mount itself being billet and very nice single large bushing. There is a good amount of NVH but then again if your wanting a really rigid mounted motor you want the best possible solution over oem and bushing inserts.

 

Glad to have helped you get what you want out of your MINI!

 

I am honeslt very surprised it has taken someone this long ti come up with that item. Any work for the tranny mount? I would be VERY interested.

 

Glad to hear you interest, and without even having one of our mounts yet!

How much more NVH do you have with this mount. Is it more than you had with the powerflex bushing insert? I wouldn't think that was a good thing. Does the street version produce less?

 

Safe bet being the lower mount, and since it's made of a piece of billet aluminum the NVH is pretty harsh.....

 

The type of metal shouldn't matter. OEM is aluminum. It's the bushing material that makes a difference.

With handling the track bushing is harder then powerflex poly.

Its pretty hard to say because everything is very hard from the crazy cold temperatures we have been getting here in kansas so everything vibrates, rattles, and just seems way stiffer. Once things warm up and soften up I will have a better idea. Currently its 25* and it takes 30 minutes for my oil to even get near normal operating temperatures.

 

Let me know when it gets warmer how that mount acts. I have the Madness
insert in mine, really don't notice much NVH. Cheer up. I live out side of Buffalo. 25 would be a heat wave around here. Car is sitting in garage till April 1. I do like the idea of that mount though.

 

Right on man Ohhhh right you are up in the NE i was thinking for some reason your on the west coast. Did you get any of the 30+ inches of snow that places were getting up in the NE?

 

With the Street bushings, there is a substantial decrease in vibration over the Race version. That being said, the Race version is set up for just that, a Race car, that isn't worried about vibration and is only concerned with getting the power created by his engine to the ground. The Race version doesnt have much vibration if you are on the gas

Correct However OEM is a cast aluminum (which does have flaws) whereas the BSH Lower Motor Mount is a Billet Aluminum and the Mount is machined from a solid block of 6061

 

Here is a side by side of the mounts. Note, the BSH mount has not been anodized yet to give you a better comparison without all the glimmer.



More about the R53 Lower Motor Mount

Aside from the obvious bushing difference, this is a much sturdier mount. Ive seen the stock fail time after time at the bushing, and although rare, Have seen the actual cast mount snap

 

Dont need to have one to see actual quality, even through a photo. My tranny mount is do for replacment, so the sooner you guys whip something up the better . I think just a bushing replacment like the front control arms would be adequate .

 

I understand what you are saying about the billet casting. I guess my guestion is how much stiffer is the street version compared to the OEM with the big bushing insert and smaller replacement bushing like the Madness or powerflex replacements. I track my car 15-24 days a year with the Madness inserts. Very little NVH but a big difference in having less motor movement.
Still very streetable.

 

The Street kit utilizes a 70a durometer bushing on the main and is solid mounted on the secondary. Please compare the durometer we use vs the competition. By removing one bushing entirely, strengthening the primary, and increasing the case strength overall, we have created a part much better suited for the performance minded enthusiast.

We tested multiple durometers before deciding on what we are calling the street as we are well aware that a high performance DD is nice, but one that you are uncomfortable to take discriminating friends, clients, or significant others out in is a no go.

The Race version on the other hand is quite a bit more aggressive. It utilizes an 88a durometer bushing. Once rolling there is very little increase in NVH over stock, however at idle or when beginning to move there is enough feedback for us to feel the need to give it its race designation.

We strongly suggest the street bushing for most drivers and are also willing to sell the race bushings at the same time as the mount so you can swap back and forth for your different needs.

 

Thanks for the info. Very helpful compared too some of the suppliers in the MINI world.

Thanks again.

 

I would bet the cast one is heavier.

It has more to do with noise frequency and how it is transmitted from one point to another depending on the density of the metals.

 

Im back after a bit of a hiatus, and have a PSQ (potentially stupid question).

Is this mount a substitution for the leak-prone, black-goo-filled mount that comes stock on the car? Does it also 'smooth' the shifting? IOW, when I put my now broken TSW engine damper on my Cooper, the car would bounce around less during shifts. Does the BSH part solve both of these problems? If so, the street version looks to be for me.

 

this doesnt replace the passenger side mount that is liquid filled. The TSW mount does that. This mount replaces the lower mount that connects the engine to the subframe

 

Correct.

 

Okay, thanks, guys. However, I am a bit leery in dealing with TSW because I have made a couple of inquiries here about my broken engine damper and have gotten no response. Anyone have any idea how to contact them? Email? Phone?

 

Give Jeff a call
They pick-up the phone, and have responded to my email. You will find both on their home page at: http://www.txwerks.com

 

For those viewing this we have a few prototypes for the passenger mount under design review. None of which are similar to anything presently available.

 

Any idea how long. My upper is shot. Looking at both before the season starts in April-May up here.

 

Could be as little as a month, to as much as 6.. There is alot of work done by many different talented people to make this part and get it to you. Hope that helps you configure your game plan.
