Here is info and pricing for a limited slip differential.
http://shop.eurocarboutique.com/Cayman_S_Limited_Slip_Differen_P462C145.cfm
Any info on how much this will cost to install? I think this is the first performance mod I'd do. Can't benefit much from a supercharger if you're not powering the correct wheel.
I was told 4 to 5 hours approximately to install and it does
not
interfere with ABD, ABS or PSM.
Guard Transmission sells one for $2450. Torque bias or limited slip.
Farnbacher sells one for $3k

Great information... I'm calling Guard tomorrow to gather more info...
Does any one know who is selling the quaife?
quaifes are great, totally maintenance free, and very smooth engagement. they only working under power so the will not provide the stability a clutch-type can under braking & turn in, but i guess this is not an issue for the cayman anyway. quaife always warrantees them even under racing conditions.
If torque biasing works like an open diff when the wheel is off the ground, then how does it improve cornering?
it doesnt if you corner on 2, or 3 wheels. if your lifting an inside rear wheel on a cayman you have bigger problems. that is why you dont put a quiafe in the rear diff of an evo. that is only an issue if you do ALOT curb hopping. don't know too many tracks in the US with tall FIAstyle curbs, and not too man people in DEs drive aggresively enough for that to be an issue. just my 2 cents, i dont even have a cayman, tracked a lot of cars (rwd & awd) with quaifes, or somekind of torque biasing diff.
But in the less extreme case of cornering, the inner wheels are always going to have less traction (not zero) than the outer wheels. Would torque biasing diff help distribute more torque to the inner wheels, thereby improve cornering?
I agree with the 'ringmeister. I run a Honda DC5 Integra Type R, which is FWD with a Limited Slip Differential. It most definitely pulls the front of the car INTO the corner. In the case of the Cayman it should help, especially in tight corners, by pushing out the back end.
Thanks. That's good to know. In my case, I don't envisage the situation whereby complete traction is lost at some of the wheels (all roads are pretty good here) but fast cornering for street use is what I desire.
