The Big LSD FAQ thread (About various Limited Slip Differentials)

Locking percent on a CLSD is only adjustable off the car. The Nismo 1.5 LSD has an on-the-car preload adjustment but that's not something you adjust between track sessions. Its more an adjustment from street to track and back again. Having run one of these Nismo units in my 350Z the range of adjustment on the peload is not significant.

it would take a pretty advanced driver, on a thoroughly sorted car, and knowing what tracks to try what settings at, to justify playing with lockup on the diff. I've never once adjusted the Cusco on my car. Even at it's lowest lockup % it's still roughly more than 2 x the lockup that a brand new factory VLSD has (which only goes down with age)

yeah no fun at all!
when we were involved on one of the many E46's running in World Challenge a few years back, I recall we had a few different diff setups...and even those were heavy! All we had to go off was driver feedback, zero datalogging lolol - a bit old school

lolololol - you knew our driver I see
he knew how to use google, that was his biggest issue. Instead of improving him, he always tried improving the car...meanwhile, as often happens, the car was more capable than the driver

I could be wrong but I don't think LSD's assist with straight-ahead performance. I thought they were for putting traction to the wheel with least resistance (mostly in turns). I guess it might be somewhat helpful for straights?

Open diff = one wheel burnout
LSD = two wheel burnout

Yes I am bumping a REALLY old thread
I am stuck, I cant decide between the OS GIKEN and CUSCO RS
any benefit between one or the other, any reason I would specifically want to choose one or the other?

OS - a bit smoother engagement vs Cusco (its close but the OS is a touch smoother). Any adjustments have to really be done by OS, which means taking the diff out and sending it back to them unless there is an authorized OS 'pro technical' shop in your area.
Cusco - user adjustable for lockup (60,80,100% in manual cars), and for direction (adjustable from 1.5 to 2 way) Diff has to come out to make lockup adjustments, but can still be done by the user (instructions provided on restacking the plates)
Both work extremely well
