About 8 months ago I took the liberty of installing a aftermarket cluch and short throw shifter made from TRD by Toyota for the Matrix, the install was smooth and done by a local toyota dealership for my 03 vibe GT 6 spd. Since the install both the pontiac and toyota dealerships have called GM and told them that all Vibes should come stock with that since it is such a great improvement. I love the tight and short throws of the shift kit. the only thing I dont like about the cluch is that the sweet spot is sooooo close to the ground on the peddle that it makes it hard for a person who is unfamiliar with my car to shift. But as far as the short throw shifter GO WITH TRD THEY ARE GREAT!!
