Whiteline rear diff bushing kit

[tangcla]

Just wondering what exactly this part would do in terms of power, NVH etc?

Stolen from the site;

Key Feature and Benefit
Low compliance polyurethane inserts that fill the voids of the OE bushing which reduces initial torque loss & movement through rear differential mounts during acceleration & deceleration.

So i'd assume from the description that there will be less play/slack in the diff/chassis mounts...
How thats more power... dunno ;p
