Clean and easy

Easy to install, might take a couple times adjusting the nut but shouldn't be that bad if you're paying attention. The **** itself has the perfect weight to it, looks great in black to go along with the interior. Makes the shifts feel more direct and smooth for me, and I love the feel/quality of the **** just in general.

Luke,
