Has anybody had any experience with the inserts for the stock rear MZ3/MS3 motor mounts made by CorkSport. Seems like corksport makes quality parts and could manufacture a full motor mount if needed. I was considering the Streetunit Street motor mount. 115.00 for street unit, 35.00 for Corksport insert. Not trying to be cheap, trying to be efficient. The car will have the Mazdaspeed short shifter with bushings.

The Corksport inserts help by removing the open areas in the rear motor mount, but the rubber in the stock mount is still quite a bit softer than the aftermarket units. If you'd like the split the difference I've got a CP-e rear motor mount up for sale with about 30k on it that I took off my car before I sold it.

Which insert do you have in the CP-E? I have heard good things about those too. Picture available by any chance?

Since I am talking rear motor mounts. Anyone care to offer opinions on the dogbone style mounts v. the billet types?

Jamesbarone racing suggests that the side mounts are NOT needed with the Chrome molly dogbone style, but I am guessing with an 88 durometer, that they will vibrate the hell out of the car.

I have been running the Corksport inserts for years with no complaints. This was the first mod on my MS3 back in 2007 :-)

Do you happen to know the difference in the colors of the inserts? That is one thing I haven't seen yet (though it was late last night).

There's no difference other than the color.

Thanks. Perhaps the color change was to be sure that small critters can appreciate color coordiantion while under the vehicle?:mellow:

Well, the reason why I got a polished stainless steel cat back exhaust system was so I can look at it and appreciate it while changing my oil

That and it sounds better:p

An 88 duro RMM alone will not vibrate the hell out of the car. I had a 90 duro SU RMM and barely had any extra vibes at all. Once the side mounts went on, however, I was well in touch with every noise my transmission made.

I didn't have to get a polished kit to make it sound better.

Still looking for more feedback regarding the dogbone style mounts vs. the billet mounts. I know I like chromolly for my park/dj bikes cause it can take a beating.

However, the inserts or perhaps Justin's CP-e may fit the bill.

Tut, do you notice vibrations in your MS3 with CP-e?

When my Speed's a-rockin', don't come a-knockin'?

Not really, she seems pretty solid. I don't even know what a "billet" is, so...yeah.
