I'm looking to set my car up for time attack/rally course driving. I want something that will hold the power down, keep all wheels moving at pretty close to the same speed/power band and also something that I can rely on. I love breaking the car loose for drifting as well so taking all 3 of those factors into consideration please advise on what would be best. Thanks.

Thanks I've been looking at this one but it seems this is pretty much the only one out there? besides maybe 1 or 2 others.

 

I have a wave track on the front for mine ( doesn't free wheel if airborne on one side like the quaife does- torsion based LSD) and an os geiken rear hard core set up would be ralliart super traction though.

 

Shep trans offers some rear diff upgrade options too.

 

shep trans did my os geiken

 

Yea I'm gonna end up going with the Wavetrac lsd in the front and center. I'm just going to re stack the rear differential since we all got F'ed by the USDM market if you have a US spec Evo.

 

You don't need an aftermarket rear diff, you just need to re stack it.

For all USDM versions of the Evo they purposefully stacked the disc's and plates wrong so it causes understeer due to the fact Most Americans don't know how to corner so the are "protecting us from ourselves". Then again it could have been "Big Brother" know it all Government stepping in and putting some horse crap regulation on yet another aspect of our lives trying to control us. Anyway it happens that link will help everyone make their car drive like an Evo and not an STI.

 

Wavetrac is good for the front. If you like to drift thru a corner than get a 2 way. If u need grip thru a corner u opt for a 1.5 way lsd. And then you need to decide how much lock u want 40, 60, 80 or 100%.

I'm certain tre or shep can adjust ur lsd which ever one u decide on. I like the O.S. Giken Super Lock for the track. If ur going to street ur car just go with OEM RS LSD. its an inexpensive route over at TRE.

 

Wait a minute - does this mean the USDM IX RS evo comes with a properly stacked re-end?

I'm preparing to do this job next week and would be livid if I got down to the plates and found it was already stacked correctly.

Can anyone else who drives a USDM IX RS confirm?

 

The only thing I have heard about from the USDM Evo's having stacking issues is the REAR DIFF. They stacked those plates wrong but the RS Front LSD from my knowledge is stacked properly.

The USDM Market stacked the Rear improperly because most Americans don't know how to drive and it saves from causing accidents from oversteer or the back end kicking around on a launch. Now many of us don't have this issue, but there are a lot of idiots out there .

 

wavetrac Center diff? i didnt know that was avalible.
Thought it was just the Quaife and the LOL 2 thousand buck Cusco.... for the center diffs, QDH11B and QDH13B for the 6 speed.
I have the Quaife Front diff in my new transfer case, not installed yet thou.

 

once you restack your stock diff you'll realize why they stack them the way they do from the factory. Noise. everyone that gets in my car asks what's broken.

 

Can anyone confirm if the IX RS USDM evo came with the diff stacked properly????

 

The front diff is a torsion diff in the RS, there are no plates to begin with, much less stack them properly.

+1 on the rear being changed simply because of noise as griceiv mentioned.


Do any of the aftermarket center diffs eliminate the viscous coupler in the transfer case?
