Or is it a completely different system altogether? I've read online that it was lifted from the Evo IX but couldn't find anything to back up forum talk...

 

^true. there is confusion due to early press releases saying 'EVO IX components'

AFAIK it is a RA-specific part and 'simpler' (cheaper) than the EVO X unit.

 

front differential and transfer case are exact same as the evo x mr. The rear differential is something else. The ralliart rear is a mechanical limited slip diff while the evo has active yaw control diff.

 

Good to know. Thank you both.

 

Wonder how hard it would be to install an Evo X diff in the RA.

 

it has evo 9 awd components.

 

Rich

 

Transmission is same as MR except for gear ratios. Transfer case is same as MR with ACD and all.

Rear diff is *like* the USDM Evo 8/9 because it does not have AYC like the Evo 10 Therefore it doesn't have "SAWC". However it is a different physical unit then the Evo 8/9. This also makes it stronger than the Evo 10.

 

 

People go to great lengths to get rid of the Evo X diff...

 

why is that? whats wrong with the sawc?

 

Bumpity bump bump.


What are the issues with Evo X rear diff? Just wondering

 

Pretty sure they can't handle a lot of power. Also from reviews they are not very good in a slalom course

 

Interesting, thanks for the info.

Completely anecdotal, but my previous car had in it's final model years a very early implementation of an electronic rear limited-slip differential (0-100%). Lockup wasn't as smooth and predictable as the completely mechanical LSD found in older models, so it was often 'downgraded' to the older model's setup.

Sometimes simpler is better

 

simpler is ALWAYS better.
