Motor Mounts -- Why the price range?
Looking at new motor mounts and trying to figure out "why" the price range is so so wide. OEMs at $500 range yet after markets from less than $200.
Do the after markets require the OEM mounts? Do the OEMs come with New mounts (arms)? I know OEM is almost always more, but this seems like a huge gap. Thanks for any insight, ppritchard |

OEM is extremely expensive for what they are, but they should cost more than aftermarket ones. Most aftermarket mounts are just pucks of poly cut to the right size. OEM are basically filled with hydraulic fluid to help with the cushioning.

Yes, they will require the 'arm'. While not absolutely required, IMO the steel arm is preferred for both sides. No. |
3rd gen Classifieds or ebay, I bought a pair a few weeks ago here for 60 shipped with some aftermarket mounts.

The high price of the OEM mounts DOES include new steel brackets

Reminds me of of the suspension busings.... It was cheaper to go with a complete Powerflex kit, then buy new OEM.
I installed the stiffer IR Performance engine mounts (they have two different stiffness's available) and couldn't be happier. My car is primarily a street car. www.irperformance.com Right on their home page, and their on SALE! :D |
because aftermarket mounts cost no more than $100 to make? and they use the stock mount arms.

nope, all factory mounts come with the arm. i don't think they make the aluminum version anymore anyways.

Why replace the aluminum with steel? aren't the aluminum lighter? are they more brittle? did they come with some sort of defect?
|
The rubber is formed around the aluminum brackets. The rubber is bolted to the steel brackets. It is my opinion that Mazda motor mounts are in a league of their own.

The steel mounts allow the rubber portion to be replaceable, since it is bolted to the bracket. The aluminium bracket has the rubber bonded to the arm, this nearly always tears off causing a failure. The aluminium brackets needs to be modified to accept replacement poly mounts. http://banzai-racing.com/store/FD_po...or_mounts.html

Is it accepted that Noltec mounts are the best?
|
so our cars come with 1 steel and 1 aluminium arm? why not make them both steel or both aluminium?
|
Most people do go to two steel brackets for the ease of installing aftermarket mounts or when they find that their left side mount has torn apart and they call Mazda for a new one. It is not practical to use two aluminium brackets as the right side steel mount has a heat shield to protect the rubber or poly from the heat of the manifold and turbos.

Around how much do the steel bracket go for?

Personally, I think the OEM mounts suck. Overpriced and failure-prone. Plus, I can tell when an engine has OEM mounts.....grab the UIM and pull. The motor moves around like a jellyfish, and this is when the mounts are in good shape. Lastly, they make R&R'ing the engine in the bay more of a PITA. For certain customer types (or like my old man :lol:) they DO make sense and we do recommend them. For about 95% of typical FD owners that I deal with, you can take the OEM pucks and toss them. We have a shelf full of them if anyone is interested ;) Comes down to personal preference, but I love the Poly mounts. Done right, they're stiffer yet transfer minimal vibration. Lead to a drivetrain that doesn't flop around, crisper shifting, and quiet frankly no need for an engine torque brace. All of this is just IMO of course :) |

Without defining 'best' we can't really make an informed statement. This isn't directed at adam by any means, but when I see threads where someone (usually a newb) asks "Which blah-blah is best?" I just shake my head. Reminds me of an 8 year old in the aisle at Toys R Us. "Which turbo kits is best?" Um, yeah.

I honestly felt no difference when I put poly mounts in my car, the shifting just got a lot better. The rotary is a smooth engine to begin with. Now when I did poly mounts in my s2000 there was a huge difference, the whole car felt like it was shaking and the shifter bounced back and forth in neutral. I feel like for the fd you might as well do poly mounts, doesn't change ride quality just makes shifting a lot nicer.

A friend of mine put them in his FD. His car was miserable to ride in. He took them off, and went back to the oem mounts. A huge difference in vibration.
