recon f20 gearbox and how much difference lsd makes

[inushmiah]

im going to recon my spare f20 and because its going to be
Stripped
i wanted to no hw much difference an lsd makes before i get one (never experience one in small hatchback)
im after a Opel Astra F20 ATB Helical LSD differential am I correct in assuming this diff will prevent torque steer as well as better cornering , i have never fitted one before is it easy to fit and will it be noisy when driven



thanks all
