We're all in different places when it comes to braking. I've moved from braking as hard and as late as possible to bringing my braking points back a little sooner, braking less and getting on the gas sooner. According to my logger, I'm losing time coming to the end of the straight braking sooner, but braking less and being able to get on the throttle earlier carries all the way through the next straight and often results in overall time gain, not to mention it feels like I'm upsetting the car less. I suppose eventually I will seesaw back the other way, but for now braking really late usually also means over braking (for me).
Sorry, all but the most committed are on summer break from driving out here in the Southwest as most of the race tracks are out in the desert (or near the desert); this time of year the brake fluid isn't the only thing that gets cooked. I need to take my mechanic's hat off and put my driver's hat (helmet?) back on:
As you correctly point out, you always
want to optimize corner exit
going onto a straight, especially the longer ones. This is what some call a "Type I" turn, and the launch out of the corner onto the straight is everything
However, when coming into a tight turn at the end of a straight, especially one which does not immediately lead to another long straight, one of the options is to carry all that speed for just a little bit longer, turn the nose towards the apex, and then slam on the brakes (remembering to release them at turn-in
).This is what some call a "Type II" turn.
As an example, one of the tracks we run in Southern California is the "roval" layout at AutoClub Speedway in Fontana, where you fun flat out down the front straight, carry as much speed as your right foot will let you through NASCAR Turns 1&2, floor it coming out of the banking down the back straight, and then slow way down (to around 40 mph) before diving left into the infield part of the course at Turn 3. You could easily be sailing down the back straight at over 130 mph, so for every tenth of a second you stay on the gas and don't coast or brake, you are closing huge amounts of distance and time on those who do coast and/or brake gradually before arcing into Turn 3.
As the left hand turn 3 is followed almost immediately by a right at Turn 4, the two make kind of a chicane, so even if you brake really
deep before 3, as long as you gather it up through 3 and get the car pointed in the right direction for 4, you can make huge gains on those who enter slow and drive big lazy arcs through these two turns.
And yes, Turn 3 can be really
hard on the brakes AND the oiling system. And it's where most all the carnage occurs in club races...
Anyway, back to the garage...
