The standard diff unit’s componentry falls well short in the performance stakes. As an absolute minimum you should fit an up-rated diff-pin - whether this is because your racing regs don’t allow alternatives, or merely for the road - along with new planet-wheels and thrust washers.

Fitting an LSD isn't as simple as replacing the diff cage unit. In all cases a certain degree of diff housing modifications is needed - material needing to be ground/filed away to provide clearance for larger diff housing cases and crown wheel bolts. Although it has to be said the Quaife diff is supposed to fit without these mods. I've never found that.
