The aftermarket replacements are a regular 3 mount from what I have seen. The regular 3 has 3 open areas in he rubber. The MS3 has 2. They are selling the wrong mount.
I got a factory Mazda MS3 mount. 2011 model. Any year should work just fine. This one looks just like the one I had on my 2008 model.
If you look at my mount you will see that the top is solid rubber. That is the MS3 mount. The regular 3 has an extra slot at the top and the bottom is the same as the MS3. 3 slots vs 2.
My last car was a MS6 so I'm pretty familiar with the entire platform as well. I'm thinking there could be all sorts of carry over items.... but I guess we'll just have to wait and see.
Beings that the inserts are like $35 and I'm pretty sure I can con someone into giving me their stock rmm on msf.org.... I might be giving that a try.
I'm really having some heart burn over whether I want to go with a OEM MS3 mount with CS inserts or an aftermarket RMM.
I had a 75 DURO RMM on my MS6 and over time it started to loosen up and obviously the difference over stock became less noticeable. I'm just worried that if you start with less noticeable... as the inserts break in, you're basically going to be back to no change over OEM.
Anyone tried filling the stock mount with urethane? Back in my SHO days, there were no aftermarket mounts, we all used to make our own mounts out of stockers with urethane.
So I just got the MS3 RMM with the corksport inserts installed. So far I'm loving it, however I will say the vibes will probably be more than most of the 'mpg junkies' on this site can handle.
The car goes into gear smoother, the car takes off smoother (less the vibes) and the car shifts a hell of a lot smoother. You just feel more connected to the car.
The idle vibes aren't really noticeable... it's just during your initial clutch release things get a little shaky. I'm sure it will die down as the mount breaks in.
I would be interested to see if this gave you any drop... I know you're looking for the spring rate... but regardless of the rates I would neat at least a .5" drop to go through the hassle. I'm also eyeing things like aluminum shifter bushings and other random crap.
Thanks! I sent the guy a PM. I would like to try the dampers too, but I am unsure of the mileage (you never know). If these work, which they should, it will give us all a nice alternative...
I started doing some research to see whether MZ3/MS3 and Volvo C30 dampers would fit our cars, but I'm currently sidelined with a wrist injury and unable to work on my car and take measurements to see what will fit.
With the rear shocks, there seems to be a difference in the lower mounting bolt and it's size, depending on the year of the MZ3/MS3.
Here are Koni part numbers for the aformentioned vehicles:
MZ3 ('09)
Front: 8741-1487LSport & RSport
Rear: 8040-1350Sport
Just put another 15-20 miles on the MS3 RMM with CS inserts and I'm still loving it. Everything is so much more crisp. The car is 10x more enjoyable if you can handle the vibes.
I would probably stay away from OEM MZ3 parts... I can't really see them as being much of an upgrade over what we already have. The MS3 parts could provide potential however.
I have heard of a lot of Gen Juan MS3's blowing shocks but I have no heard as many accounts of the GenPu's having this problem.
Good call though, I would definitely steer clear of Gen Juan's dampeners though.
