Default Beatrush engine and transmission mount review 05 STi

Just installed the beatrush engine mounts and tranmission mount on my 05 STi last week. Did it in my garage on jack stands while jacking the engine up at the oil pan (using a piece of wood to disperse the weight). Used the following thread as a guide for installation (http://www.iwsti.com/forums/how-inst...ne-mounts.html).

The motor mounts are definitely a bitch to get off. I have know idea how people can break the rear bolts with a wrench, I even got the longest 14mm wrench I could find but it still didn't have the leverage to break them loose. I ended up disconnecting the TMIC, pitch stop and both mounts from the subframe so I could lift the engine enough to get to the rear bolts with a flex head ratchet and 14mm socket. (http://www.sears.com/craftsman-3-8-i...&blockType=G11). After I had the new engine mounts installed I grabbed the motor from the top of the engine bay and guided it back into the subframe while lowering the jack down.

Pros:
Car feels much more solid when cornering.
Super smooth gear engagement. 2nd-6th
Increased throttle response.
No torque steer.

Cons: extra cabin noise

Overall I'm very pleased with the upgrade and the quality of the mounts. My best description is that it makes the car feel more like a muscle car. Yes the engine mounts do transfer a lot of noise but the vibration on the other hand was better than I was expecting, it really isn't all that bad. I personally didn't notice any increase in NHV from the transmission at all. I also have a full polyurethane bushing kit and the whine is minimal. I would say the Beatrush transmission mount would be a good upgrade for anybody. The engine mounts might not the best for a stock DD but are definitely a good upgrade if your running a larger turbo and wants to enjoy the extra throttle response.

Not my pics but a good comparison of the two mounts vs the stock units.

Did you actually use the oil pan as a jack point?

Quite a lot of people use this as the main jacking point to do motor mounts. Op, how do these compare to the Group N mounts? I like my group n mounts but they are starting to feel "soft" after 2 years of use.

One thing I suggest when using the oil pan as a jack point is to use a block of wood or something wider to dispurse the weight of the motor so that you do not puncture your oil pan.

Poly mounts are junk. Destroyed some motor mounts of crappy quality.

Yup. used a piece of wood with no issues, three months later no leaks around the oil pan. I also have a jack with a fairly large jack point.
