Kaaz come as a 2 way diff - though I'll be running it as a 1.5 way to make it more driveable on the road.
My Avatar is actually the Zed at Mondello - hope to give it a proper run a few times this year.
I won't be going down the road of Launch control - I'm hoping the extra traction from the R888's and the Kaaz will be sufficient to see me into the 4's for the 0-60 sprint and the late 12's for the 1/4 mile. The standard viscous diff is really pants for getting power down esp when you add FI.
not the master of diff's but think they do 1,5 / 2 or solid ;-)
was going to go down this weekend but Z is without ecu at the moment so that didnt happen, nice and crisp today would have been perfect around the track 4's is silly fast anyway
(I'll beat you on the bike though)
