[QUOTE="fabianyee, post: 608870, member: 6"] There are 3 types of LSD... Clutch type, viscous, and helical gears. Clutch type LSD is the most common in RWD cars especially for drifting.. and there are oso different types : 1 way, 1.5 way and 2 way depending on the ramp angle. basically lock on acceleration or/and deceleration. read up more online. It may cause the DSC to trigger unnecessarily although the LSD does allow enuf slip otherwise, the inside wheel would be chirping especially when taking slow sharp turns on smooth cement surface. I didn't notice that. only the high percentage lock LSD would have this issue. BMW clutch type LSD has either 25% or 40%. Viscous type more for centre differential for AWD cars. Helical gears is fully mechanical and virtually maintenance free, it can distribute power from 0-100% between the wheels. Quaife is helical gears. this type won't affect DSC or any driver's aid. However, for it to work, both wheels must have traction even if it's just 5% on 1 wheel. When 1 wheel is lifted off the ground (0% traction), it will spin free like an open diff. And also not preferred for drifting... Good for track use... Best type of LSD for FWD cos it won't have unnecessarily hard steering kickback when accelerating out of corners. U can research all 3 types in the web... [/QUOTE]
