I think both eliminator77 and markp run Torsens, I THINK. Don't quote me on that. Eliminator I know still runs a 7" diff, and even at whatever ungodly power he's making now, he hasn't had any issues with it.

NEVER LIFT <3

yes for as much as my kaaz keeps the ass glued in corners, ANY amount of lift makes the nose of the car dive into the corner. power-on corner traction over an open is about 500% better though. the open guarantees you lose one tire's worth every time.

So where did you Kaaz people buy your differentials at? How much did you pay? Are they that much better than the mazda torsen?

I got mine from Kaazusa directly. Great service and decent shipping to the netherlands too :)
they had my diff. on special offer so the total price including shipping was about the same as the normal price :)
I payed $972.50 exactly, including shipping and some stickers. They marked the box as warranty repair too so I did not pay any taxes for it.
