how arupt is braking

when racing? should it be just the same as braking hard in street driving but harder/quicker but not slam quick?

I've noticed at times slamming on the brakes with abs kicking = same or more most of the time as smoothly just braking, but no tire noise.

Depends, I have raced on tracks and streets, and done few quartermile runs, then there is left servial forms of raceing, anyhow, I havent ever slammed the brakes, unless there have been obstacle on the way, wich I cant pass from anywhere, and I dont have "2nd way" to turn on.
Never crashed due of this though, but zillion close calls.

But anyway, what do you mean with "raceing"?

Of course you'll be hitting the pedal harder since you're going faster and braking later, but in the end it's not about how you brake, but when...

was just wondering. I used to burn into corners with my old car (slush), and I've toned down a lot since then, but occasionally when bored, I do get the urge to brake hard from a decent speed into a corner on an empty road... so I asked lol.

I've been taking corners 1 gear higher than normal these days. Been bored and been taking corners faster. I love it when my RWD understeers for a split second while taking a 90 degree corner in the rain.

I am expecting to get flamed for this post, lol.

hint: start turn in towards corner, stab clutch, rip e-brake, drift around corner, let out e-brake, rev match, let out clutch, stab gas

have fun

What kind of RWD car do you drive that understeers? Sounds awful. Most RWD cars oversteer, allowing you to powerslide (or as the kids say, "drift") in extreme conditions.

Take ANY older RWD car, and try to get fast in the corner, turn sharply, without accleration, and you will find yourself in heavy understeer, older american cars, (like 80's caprices and such) with not too much power, will understeer even if acclerateing.

Exept, if you know how to do "scandinavian flic" (possibly known in other terms outside europe)

Good point, I must have forgotten about underpowered RWD boats...which is truly odd since I own one.

you should not quite slam it, but more like squeeze it to max pressure without locking very, very fast. You don't quite slam it as fast as humanly possible because the extreme weight transfer could be enough to lock wheels. Also, as the car slows down, you need to gradually release pressure from the brakes, because as the car slows, it needs less braking force to maintain constant deceleration. If you maintain the maximum pressure from the initial braking, you will lock the wheels as the car starts to slow.

RWD street cars will usually generally understeer, perhaps less then FWD though, and manufacturers would get sued like mad if they made their cars handle "neutral" from the factory.

Power on oversteer is another thing though, if there's enough power, a RWD can oversteer on throttle application out of a corner. Even a neutral handling race car will understeer on power though, until the point of loosing traction from increasing acceleration, if that makes sense. The car understeers under acceleration because weight is transferred backwards, giving the rear more grip.

Works best for sending a FWD vehicle sideways

It understeered mid corner in a 90 degree corner in the wet.

mid transition phase from when i eased off the brakes/gas, I think i hit a slight bump/twist in the road and the front wheels lost traction for a split second, was not going balls to the wall driving in any means, just a bit faster than decently brisk/speedy, lol.

So, what kind of car is it?

you mean to tell me there are other ways to drift without the Scandinavian flick?

You drive a compact pickup...you of all people should know how to get sideways without the flick.
