Just How Far Do You Go To Protect An Index Or Win One More Round..?......is It Worth That Much..?

Just as a note, if my calculations are correct (and they usually are), scrubbing a tenth would require scrubbing more than 20 mph over a distance of about 130 ft., which is twice the distance from the MPH cone to the finish line. I'm not going to say that I'll never have somebody dump that hard against me, but so far I never have.

In most cases people have usually waited until the MPH stripe to dump, which would mean to scrub a tenth, they'd have to lose approximately 40 mph over that distance, which I don't think is possible.

I see "excessive braking" as only when there are tire(s) locked up, or vehicle control is compromised.

I run the "low smoke" Moroso fronts myself......

Jason is about dead on with his calculations.
If you want to scrub a tenth, you better have it mostly done before you get to the 1000' mark, and a tight rear brake setup really helps.

I've never had to "hold" more than .08, in that case, I scrubbed the brakes upon the shift to 2nd gear, just enough to hold the tach for a one count, that took .05-.06 off, dumped the rest down at the end between the stripes.
1/8th mile racing, had winning MPH from 84 to 102 that day.

I Think Anyone Who Is Found Guilty Of Excessive Braking Should Loose Their Licence For A Year. I Saw The Ceash At Atco In Comp. Not Pretty. Sooner Or Later Someone Is Going To Get Killed. Winning Should Not Be That Important!!!!!!

I will take the loss instead of braking hard. Winning like Ernie said isn't that important. I couldn't afford to wreck my car. We would never get back out there.
