The SB makes a BIG difference - well worth the money. I cannot imagine any other inexpensive mod making such a profound difference in the car. You notice the difference the first time you push on the accelerator and before you even get out of the driveway. Power hits right away and the car just wants to GO. Plants your butt in the seat and puts a smile on your face. When passing (auto tranny), the RPMs come up faster and the car downshifts sooner. I will definitely have to pay a little more attention to the speedometer.

I had a little trouble getting the washer out - it seemed to be binding between the post and the housing. I would have never gotten it out without a magnet pickup tool and you cannot remove the pedal assembly without removing the washer. Other than that, installation was a breeze.
