I got these as an xmas gift from a buddy. He really shouldn't have, but I was obliged and got a tear in my eye thinking about missing the rear end *thunk* on hard shifts.

These things are perfect for anyone who wants to stiffen up the rear diff but not go to a full solid mount. They are basically 1/2" thick donuts with metal washers that replace the factory pieces of similar size, but they do NOT replace the center section of the stock bushing. This means install is a BREEZE.

I helped a buddy install some Energy Suspension bushings, and it literally took 3 hours to get the old bushing out and new one in. It was a royal PITA, but they worked awesome once finished.

These Beatrush bushings literally took 10 minutes to install. Just unbolt the center bolt going through the bushing, then loosen the 3 bolts holding the mount to the diff and remove the two closest to the bushing. The mount swings away from the frame and you just pull the old insert out and put the new one and washer on, then stick the whole assembly back together.

Once installed, these things work exactly as expected. Power is put down to the rear end much more precisely, the rear end is tighter under acceleration, you can really feel the difference! There is a small whine that I hear now under some light load/cruising circumstances. In 4th gear, around 5500rpms, I can hear a decently loud whine coming from the rear end. It's almost like a supercharger sound, really damn cool. I assume its just more sound from the rear end resonating through the frame. I do not have much whine (if any) in 5th gear while cruising, so overall I am 1000% impressed with these. They are going in the $100 thread for sure, if they're not there already. I fully endorse these to anyone, at any level of modifying your evo.

 

They're already in the $100 thread

The upper and lower bushing inserts are different sizes so when installing be careful to put the thinner one on top and thicker one on bottom. Definitely a great product though and so much easier to install than my Energy ones!

 

Also, these are bushing inserts, not actual donuts. Real donuts will not work in place of these Beatrush units, the chocolate frosting would get *everywhere*.

 

where can you get these cheap? I'm sick o' the THUNK!
