... you will be able to shift gears in your BMW just like a "normal" car. No more vague, inconsistent clutch engagement. No more jerky 1-2 shifts. You can actually chirp the tires when shifting from 1st to 2nd gear! Parallel parking becomes a breeze and your clutch will love you for it and last much longer. Best of all, your passengers will stop making fun of your driving skills.
