All i can say is WOW at the difference between the stock 03 open diff and the new quaife!!! The car seems to pull me through the corners and is 100% more fun to drive!!

I wish i would have invested in this upgrade earlier, but i'm cheap and waited to find the right deal.

feel free to chime in if you've had it done or looking to have it done!

 

Hey! Thank for the info. i'm looking into this myself as I think it'll help the launch. I'm debating between the stock 04 helical one on sale at TRE for $800 and this one.

 

I knew how great that would have been to do to my 03 when I had it, but I chose to get a IX instead. The ACD made all the difference in the world. Congrats on the purchase!!

 

yeah i found a great deal on one, i paid 1300 total for the part and installation!!

but yeah, the 04 RS diff i hear is the same thing, its just that no one WANTS to get rid of it unless its a crashed evo partout
