Well theres a red and a black bushing kit from ES for the rear diff. One is harder than the other....I'm not sure which one is which, lol. The black ones is the one I got. The driveshaft doesn't really come in a kit with the rear diff ones. You have to buy it separately.

 

Do you remember the product number for the rear diff bushing set?

-Jalal

 

The part # is 5.1108G. But actually it seems like the same part can come in red or black. But Nate @ MAP said there is a difference in the stiffness....

Is this it??

 

Yup. I might have a slight caveat to add later about the sound. For a while I thought the downpipe was rattling against my underbrace. But today I adjusted my underbrace so that there was about 1.5cm clearance from the downpipe, but I still heard the sound in the lower gears. I'm still leaning towards downpipe rattle because its not consistent on decel from gear to gear.

 

i have energy for rear diff and mustache bar - i cant stand the whine at 75mph its louder than anything else in my car. will be swapping back to stock soon

 

It needs to be broken in and will get quieter. But this mod is not for people that want stock like noise levels in their car. Neither is a stiff front mount, or a shep trans/tcase, or a loud exhaust, or a walbro, etc. You need to accept some compromise.

 

been a few thousand miles. this is the noise level:

that's fine, i can just put stock back.

ah you already commented on there. my bad

 

Check post #9 for a vid.

 

Not sure if anyone asked, but are these whiteline bushing the same part number for the evo 9?

 

Yes they are. The vid is not whiteline bushings though. I replaced them with energy suspension bushings.

 

I recently did this again to my friend's car and took a few pics to help. Updated HOW TO to help.
