Any one have both the TSW mount and the BSH lower? Does it make the NVH worse than with just the TSW mount?
I have the BSH "street" lower mount and a VIP upper mount (like the TSW) and a Powerflex tranny mounts and "Yes" you will get more NVH with any non-oem rubber mounts or bushings. The more you add the worse it gets. Rubber is the softest and it will absorb the most vibrations. Adding Braces and Polly-not so much...:nonod: The stiffer the bushings around the motor the more MVH you will get. Dont get me wrong my car does not shake like Michael J. Fox but it does vibrate a "little". If want a nice cushy ride I take the wifes Lexus RX 350 buts its no fun on a twisty road at all.
Same here, I added the BSH lower mount and it vibrates more but I won't go back to the original. You can feel the big difference besides the vibration.
Do you think adding a tower brace would reduce some of the vibration caused by the tsw and Bsh mounts?
Call Steve at Custom Mini Shop, 559-320-0004, for his "custom" lower BSH mount. I have one and love it! No extra NVH.
If adding any extra NVH is a concern, just stick with the stock bushings. Refresh every 60k miles. There's a definite performance benefit to stiffer engine and transmission mounts, but you have to deal with the tradeoff.
I definitely agree with that there is added performance. I love the tsw mount now that it is sufficiently broken in. I added some dynamate to the doors to help reduce the droning low frequency vibration. I am now very pleased with the response, but though that adding the Bsh may help even more and would also make shifting a little smoother. I just didn't want to add gobs more nvh since its my daily and I drive quite a bit.
I have both the TSW and BSH. While yes it does add more NVH, I would not trade them for anything. I cannot say if just doing the BSH lower adds more than just the TSW because I did both at the same time.
I have the tsw and bsh mount also the powerflex insert for the transmission. I will say there is a lot of nvh with this set up. I wouldn't change it though I'm used to my daily drivers ending up sounding like a race car. The mini just took longer for me to get it there. Also I have a m7 stb I highly doubt it helps dampen any of the vibration.
Not at all, It will add more vibration. Its a "brace" and it makes things more rigid, its not a shock absorber.
Good point on the brace. I was trying to relate it to the way dynomat works. Dynomat dampens resonate frequencies by adding more mass to the body panels you apply it to. Was just thinking the upper stabilizer might solidify the front end making it on larger more dense object therefore dampening some of the vibration and noise. As it sounds, I'm probably just grasping at straws. Thanks for the clarification.
I'm glad to hear you guys like having the Bsh mount as well. Did it smooth your shifting any? I'll probably have to put one in this spring!
Anything the keeps the engine from rocking is good. I can use the OEM upper mount system only because I use a modified lower BSH mount. Now when I say "modified", CMS sells a BSH mount that uses a bushing on the normally solid end, which is the cause of excessive NVH. Call Steve for details
Whats the big secret with your so called "modified" BSH mount? Are you drilling holes in it to add more flex? Updated I see your mod now: "bushing on the normally solid end" With your modified BSH mount (street or race) version you may as well just used the OEM one.
The OEM rubber is way more mushy than what comes with the BSH and on the other end is a custom Powerflex bushing, way more stiff than any OEM, but still very little NVH
My MINI is set up for the fun runs in the twisties and I could care less about NVH. If I want to drive a car and not feel it I take out the Lexus RX 350.
Glad you like the way your car is My MINI is also set up for fun runs and twistys, and guess what......no extra NVH Now you factor in my stage 4 clutch and solid flywheel.....so much for OEM smoothness :lol: Oh and if I want ultra smoothness.....I drive my Lincoln :biggrin5: But kidding aside, if someone wants a performance oriented part that does not jar your teeth and vibrate, then this CMS/BSH mount is a good thing :cornut:
I have had some customers add the Cabrio braces and said the dash rattles were alot less with them. So that may help. Otherwise yes it's going to be solid to do both.
Thanks for the input everyone. The CMS modified BSH mount sounds very promising. That will likely be the next step. Thanks Way for the recommendation on the Cabrio braces. I just ordered a set from you guys. Hopefully I'll get them by the weekend so I can put them in and let you guys know how they work!
