Wcm ultralite STI differential found

[nc7s4]

Hello WCM owners,

 

I have a line on a 2004 WRX STI differential.  I did the swap a couple weeks ago after breaking the original WRX r160/ diff pinion 

 

This deal came through after my swap was already completed, but it is a much better deal than I got so thought I'd throw it up here

 

Details

-seller is asking $700 

-images I saw of it looks very nice

-2004 STI (only model year sti with 5x100 bolt pattern)

-R180 

-plated, 3.9 final drive ratio

 

This one is hard to find... If you have the wcm, you should strongly consider it.   Along with the diff you will swap the axles, knuckles, hubs.  

 

The pickup points on the STI knuckles are the same - my alignment didn't change hardly after this.

 

You will end up with a much stronger, less compliant rear end than the r160 and base WRX parts the car comes with.  Also you will get a fully blown mechanical LSD
