Default Re: Tranny Brakes

Don't recall when brakes were legalized for Super Stock but it's been that way for several years (another forum member will probably pipe in) but the vast majority of the cars have brakes. However, you still see several racers who compete very well foot braking, presumably because they feel more consistent doing it that way. It's all about what you're most comfortable with. One plus to brakes is that you may find your spot on the tree a bit easier simply by adjusting button travel as opposed to changing tire pressure, stall RPM, etc.


Based on my experience you won't get much ET reduction using a brake (~.02-.1) because of the different dynamics when shocking the chassis with a brake (if you've never used one, your back may feel it the next day and definitely have your helmet planted to the headrest when it releases). Also likely that several chassis adjustments will be required. If your car hooks well now and you have a lot of front end travel best tie it down before releasing the button or you may find yourself pointed to the sky (experience speaking). IC and shock adjustments are likely in order. As for which trans is quickest it depends not so much on power as the weight of the car since you don't have the gear multiplication of a 3 speed. 3100-3200 pounds is the traditional rule of thumb 'brake point' for a PG but if you have a very narrow torque band then a PG may drop you too far out of the sweet spot at the 1-2 shift.


And make sure your converter is built to handle a brake and if you have a borderline rear gear setup then be prepared to upgrade there or you will regret it.
