evo owner pls come in, i gt question to ask

[wongsengming]

have u all change ur LSD? change it both front and rear? for i know, it gt 1, 1.5, 2 way LSD, so which one better ?

thnx

Not many owners wil change their LSD to a manual type... Its not cheap too!!! :_: As for 1, 1.5 or 2 way LSD, u got to know all their function n how they work under what conditions 1st... Then onli u suit it to ur own driving style!!! There is no 1 definate answer to it!!! Cos what suit my driving style might not suit u...

Hope this help! If u got more Qs do drop by Mitsu Lancer Owners Club forum n post!!! :_: Cheers!!!

just to share..taken from wikipedia..

The clutch type LSD responds to driveshaft torque. The more driveshaft input torque present, the harder the clutches are pressed together, and thus the more closely the drive wheels are coupled to each other.

With no / little input torque (trailing throttle / gearbox in neutral / main clutch depressed) the drive wheels are still coupled somewhat as the clutches are always in contact to some degree, producing friction. The amount of preload (hence static coupling) on the clutches is determined by the general condition (wear) of the clutches and by how tightly they are shimmed.

Broadly speaking, there are three input torque states - load, no load, & over run. Under load, as previously stated, the coupling is proportional to the input torque. With no load, the coupling is reduced to the static coupling. The behaviour on over run (particularly sudden throttle release) determines whether the LSD is 1 way, 1.5 way, or 2 way.

If there is no additional coupling on over run, the LSD is 1 way. This is a safer LSD, as soon as the driver lifts the throttle, the LSD unlocks and behaves somewhat like a conventional open diff. This is also the best for FWD cars, as it allows the car to turn in on throttle release, instead of ploughing forward. [1]

If the LSD increases coupling in the same way regardless of whether the input torque is forwards or reverse, it is a 2 way diff. Some drifters prefer this type as the LSD behaves the same regardless of their erratic throttle input, and lets them keep the wheels spinning all the way through a corner. An inexperienced driver can easily spin the car when using a 2 way LSD if they lift the throttle suddenly, expecting the car to settle like a conventional open diff.

If the LSD behaves somewhere in between these two extremes, it is a 1.5 way diff, which is a compromise between sportiness and safety. Generally a 1.5 way creates a stronger lock under acceleration than deceleration.

Clutch LSDs are noisy, clunky and expensive, which makes them unlikely to be installed by the factory on a passenger car these days. However their response speed and coupling strength is the best of the commonly available LSDs. They are also the only commonly available LSD able to stand up to extreme motorsport abuse.
