IMO i haven t seen much people upgrade thier axles, it seems you break diffs more than you break axles, i coulsnt find anyone selling aftermarket axles, but i would say 400hp at least...dont qoute me on that one..

Chromoly Axles

 

Those axles are for an FD. What about FC ?

 

I just bought a kaaz diff haven't put it on untill I get my 1 piece drive shaft.
Kaaz is hella dope tho

 

Not to thread-jack, but does anyone use a Mazdaspeed 2 way LSD? I've just started looking at upgrading my diff and was curious which way to go. Now I'm leaning OS Giken due to Zero R's comments, but that price is hefty haha. I found a Mazdaspeed unit for a good price so I'm wondering.

And I am curious as well, do all aftermarket diffs clunk when taking corners slowly?

 

however those are for an FD, but i mean most of the guys in japan should have something, im just probably not looking hard enough...

for an FC btw.


OS Giken any day!! i have used their twin plate and their single plate clutches and both amazing did not disappoint!!! but i havent tried thier diff's, should be well good enough though just prices are bit up there!!

 

Yeah that's my main problem, it's so freakin expensive haha. That and I'm still wondering if all aftermarket diffs clunk.

 

Never used a giken but I've read alot about them (intend to get one soon) and I've read they are silent.

 

Alright Os Giken is silent. I've heard that Cusco and Kaaz cluncks when turning at low speeds. What about Mazdaspeed ? And just out of curiosty anyone tried OBX LSD ? To me OBX seems cheap but hey you never know sometimes.

 

Alright, well expensive or not, I may have found my diff haha. I can't stand clunking.

My buddy has a Kaaz in his car and it clunks like crazy taking slow turns. I'd still like to know about Mazdaspeed.

 

Can anyone comment about the Mazdaspeed LSD. And anyone tried OBX LSD just for reference ?

 

From what I've read if your KAAZ diff clunks it has not been properly broken in. There are quite a few people who have taken the time to go through the break in process and have no clunking at all with their KAAZ diffs.


Damn, that OS Giken diff makes me drool.

 

^Well, knowing my buddy, it's a damn good chance he didn't take the time to break it in, or possibly didn't even know there was a break in procedure, HAHA. Thanks for the info!

 

So I FINALLY got my LSD. Picked up a KAAZ 1.5 already sealed in the T2 diff housing for $250 . Took it to KAAZ HQ on Tuesday for inspection and some 80 90 gear oil, I was told that ring has great backlash, but my pinion gear is wearing thin.

My question is where I may find a new/decent pinion gear for a T2? Are these available aftermarket?

 

I have seen no aftermarket ring and pinion sets for these cars. I plan to look into metal treatment seriously when the time comes to rebuild my diff.

I'm not into metallurgy, but I'm talking with shops about (but not limited to): WPC treatment, cryo/heat treatment, and nitriding.

 

Quick Question:

Is it safe to assume that a KAAZ 1.5 diff has a bit "more" torque when compared to an OEM T2 LSD??

 

My first choice is the carbonetics carbon diff, followed by a good torsen diff as a second choice.
