    I am interested in knowing as well especially since it does not work on (3.07, 2.93 or any ratios lower than 3.15) which is the ZHP.

    Turner used it with a 3.64 final drive on their ZHP.

    Right. That's for auto....but they used it in 6 speed.

    For that kind of money, why not swap in a E46 M3 subframe and 3.64 LSD?

    It would be nice to run a 3.46 final drive and this.

    In the end, clutch type based lsd units are preferred since they have a fixed preload on the clutch pack and therefore a fixed amount of slip. The e46 M3 unit is fairly similar to a Torsen diff and is variable.

    i wanted that too. i think in my research there were guys running it on e46fanatics. then there were a bunch of hpf owners that swapped out their m3 diffs for it.

    I have the OS Giken superlock in my 135, had it installed over last weekend. I got the car back and its one HELL of a difference mine is also 3.07

    I was going to go with a quaife, but as I listened to the man at VAC Motorsports talk about how it won't help wheel lift situations, I decided to spend the extra and get the OS-G. My driveway is built funny and I lift the right rear wheel pulling in and my car gets stuck or spins the wheel, so I wanted that to be rectified when changing out the dif. There have also been on-track situations where you get wheel lift, so going with the quaife unit wouldn't suit me properly.

    My garage: 08' Alpine White 135i Coupe putting out 405 wHP to BOTH rear wheels. 05' LeMans Blue X5 4.8is that I like to call Truckmeat. Socketheads 05' Dinan tuned ZHP, and a few Hondas to keep it real.

    The '08 doesn't have the welded diff does it? IIRC the 09+ 1 series have a welded diff and only VAC Motorsports or similar can do the work.

    As well, you don't even need wheel lift. As long as you get weight transfer enough you'll start spinning wheels.
