Found out my rear differential mounts are definitely shot. I need to get them replaced before a track day at the end of the month. I don't really want to go back with OEM ones since I'll probably just bust them again, but I don't really want the side effects of the Unobtanium ones either (gear whine, etc). Does anyone sell heavy duty ones? I searched my usual places and wasn't able to come up with any vendors, and I really need to be getting these things ordered.

Thanks in advance.

 

Nobody's done this? I had a recommendation to try Mazda Comp's upgraded ones. You guys all using stock ones?

 

There are several types ofDiff Mount bush in Japan.
Metal is stiffer but noisy.
Polyulethan is moderate.
Which type do you want?

I use this one.
It is US$200.

 

Unfortunately I don't know exactly what I want. I definitely don't want metal, or anything else that's too harsh since the car is my daily driver. However, I've heard that if I buy new OEM ones, I'm likely to break them quickly again. The ones pictured look like what I might have imagined I might need. Were there any real downsides to these (excessive noise, etc)? Where did you purchase them?

Thanks

 

It is sold at only in Japan.
The shipping cost from Japan isn't peanut.
I will visit San Francisco next month.
If you want this products, I will carry them.
Then, the shipping cost can be saved.
PM me.

 

how much power do you have that you think you will break stock ones. Aren't many of those single guys with 450rwhp using them?

I know Jim's are noisy with gear whine b/c I have them installed. I assume metal would be the same.

 

The stockers may be fine. I'm only looknig at 275rwhp, but I autocross monthly and plan on getting track time regularly. I'm purely going on hearsay, but was told that OEMs would just break again under these conditions. I may just have to just use them again while I decide what to get next. I need to have them replaced before the end of the month when I'll be getting my first track day. Thanks for the offer inukai, but unfortunately I don't think I have that much time.

What was Jim's made from? I'd still be interested if anyone can verify that stock is strong enough...

 

Jim's are made of nylon. hard as hell. I got th em at teh time becasue they were cheap as hell, something like 80$. I came to find out my stock ones weren't even bad. and Jim's didn't add any throttle response or anything.

If I were to do it again, I woudl go mazda comp or some poly ones. Jim's are greta bushings, made well and very inexpensive. Just a little much for what I need. and I am running 14lbs of boost.

 

Thanks for the reply. I may just go the Mazda Comp route. I couldn't find anything listed on their webpage, but they must have them. By the way, does Jim have a website? I see lots of references to his stuff but I've never stumbled across an address.

Thanks!
