To those who installed the MMR diff bushings-
Did it eliminate wheel hop on launch? I would like to know if this will take care of it or if I need to take more drastic measures. |
Don't the stock mounts have space for flexing in them? I can't remember, but I seem to recall some diff mount having space and some DYI'ers filling that space with urethane to stiffen up the stock rubber.

i just ordered mazdaspeed engine and diff mounts-i was tempted to get the mounts from mmrdirect since they're half the price, but i'm not sure if i could tolerate mounts that stiff in a DD.
|
i put the diff mounts in approx 6 months ago and only noticed slight increase in vibrations, As far as wheel hop, never really had any problems-before or after. I just put the mmr motor mounts in this past week and the whole package is pretty rediclus as Brainack....
my MSM motor mounts are fs in the fs section... |
So the MMR's are stiffer than the Mazdaspeed ones? I sent them an email asking the same thing but they haven't replied yet.
If they are stiffer I'll order them immediately. |
yes they are for sure. They are made of derlin.
|
The guy that makes them lives close by me. He has a small shop with a lathe. Does the MMR mounts made to order and is pretty slow sometimes about getting parts out. He does make a good product though that's stiff as heck without as much noise as aluminum.

Well I installed the MMRs, but i gotta pull my rear out to rebuild because theres too much gear-lash. In the two days I was running them, it made engagement very crisp. There was some additional droning between 3500 and 5500rpm, but not too bad, especially considering that my 3" exhaust is not too quiet.

These are the diff mounts I have (scroll down on the right side). They were machined perfectly to fit and the rear end feels much "crisper" now. Not sure that's the right word for it, but it's sunday morning and i'm still half asleep. Now if I can find the time to do the engine mounts we'll be in good shape....my engine mounts are completely shot. |
How would I go about installing MMR diff mounts

Ive herd removing the old mounts can be a bitch, Ive herd of torching them, drilling holes in them, using a dremmel with a chisel tool. Reguardless they need to come out, once out the mmr mounts will just drop into place. Ive been driving on MMR mounts for about 2 months now, Love them. |
MMR isn't publicly selling mounts it seems anymore. You can get the same mount here though: http://www.driftingjellyfish.com/

http://iscracing.net/images/001miatabushing.jpg I have the MMR mounts with a rigid clutch disc. Vibrates like a cheap motel bed. The Super Pro's are a lot more expensive but should be somewhere in between the Mazda 40% and the Delrins. Haven't tested them yet. |

I have those sitting on my desk waiting to go in. they are my new pen holder for the time being. |
Interesting. The Drifting Jellyfish mounts are UHMW HDPE, Ultra High Molecular Weight High Density Poly Ethylene. Good mechanical properties. Much less rigid than Delrin but it should work.

Well I just found some delrin and uhmw hpde on ebay for el-cheapo (cost prolly 20bux for a set made of delrin) and can machine them at work for free, need some dimensons then I could make a few extra sets if anyone wants them, cost plus shipping would suffice. Intrest??
