MKI MR2 Polyurethane Engine Mount Inserts
[Engine Mount - MKI MR2 (4A)]

I have owned my 85 AW11 for around 4 years and the mounts had splits in the rubber back then. If yours have splits, replace them now! I wish I had done this long ago. I ordered the inserts on Friday, got them Monday and installed them in around 4 hours. There was around an extra hour and a half install time because I didn't have a hack saw or a vice and had to beat the old rings out with a bunch of random tools and a lot of banging. If you have a shop, it will probably take around an hour or so. The replacement is easy, except for getting the old rings out of the motor mounts. And the instructions that come with it are fine but there's a video or two on youtube that shows you exactly what to do. Make sure you torque everything properly. After install, the first thing I noticed is how much more of a rumble I feel from the engine now. Starting actually feels pretty neat, more like a race car. You WILL feel much more vibrations at low RPM's and until the engine warms up. I love it! Driving is very much improved. Where before I could feel the engine jerking around back there on up and especially downshifting, now it's smooth as hell. The power transfer is much better. The only downside, and it's not a big one, is that anything that could rattle, will shake, rattle and roll. So get ready to go through the cabin and tighten up those loose trim pieces. This should be on top of your list of fixes for your car.

Installed these - was pretty easy besides getting the stock inserts out. Grab a flathead and a hammer and go for your life otherwise get a hacksaw, pull it apart, reverse the blade if you need to and put it back together with the blade in the gaps of the stock mount. Cut the inside steel ring. Then start working your way around with the flathead and bend the inner ring up and soak it in wd40. Should slide out with some manipulation. I noticed quite a large amount of vibration when idling (this is with both side mounts cracked) but once driving it feels normal. Shifting is crisper and can definitely tell the motor stays where it needs to. Quite amazing the difference these mounts make. There wasn't anything wrong with my stock ones, just the 2 sides are cracked.

My car used to make what felt like a "bucking" motion where it would surge then stall slightly at lower speeds if you let of the accelerator in 2nd or 3rd gear. After putting these on it barely does this anymore. I only had a vague idea the car's problem was the motor mounts, in fact I'd entertained the idea of it being buildup somewhere in the fuel lines and did a fuel filter and ran techron through it. I'm very pleased with this product, it's a great value and will probably help you out a lot if you were having problems similar to what I described. The only problem I encountered was getting the rubber/steel stock insert out of the rear motor mount. I sawed through it as per the Speed Source installation instructions but this was to no avail. After an hour of trying various methods of getting it out I decided to try machine shops around town... One quoted me at $85, another $27, each time saying they had "minimum charges" to apply regardless of duration of the work. FINALLY someone at an alignment shop that didn't even have a press managed to get it out by smacking it with an pneumatic hammer or something. They took $10 for it. Installation on the 5SFE is very easy, no dropping of the exhaust required, the rear mount just slides out and the the side a little. All in all, I've been very satisfied with all of Speed-source's products.

Fantastic, they really make the car feel tighter and more responsive, putting power down much more effectively. One of the first things you should upgrade.

WOW, THESE MOUNTS ARE INCREDIBLE! just finished installing them on my 87 and what a difference. now i already have done all the suspension , and i mean all of it, so the car handled great before the new mount install. I just cant get over the difference 2 engine/trans mounts can make. the best way i can describe it is , it feels like i just tightened up the whole back of the car up, it corners better and accelerates better too. before the car felt "edgy" at speeds over 100 now it feels rock solid. if your like me and drive your car hard these are an absoulte must, the best 84 bucks i have spent in a long time.

I can finally really let the mr2 go on the drag strip without feeling like the blocks going to jump up and slap me in the back of the head. Excellent!
