Back in posts 8 and 9, I wrote that it's similar to heel-and-toe. One of heel-and-toe's two purposes is to not let engine drag slow down the rear tires. The other purpose is to reduce wear on the transmission synchros by rev matching before engaging the clutch provided you also do double-clutching at the same time.

To summarize, what I am describing is simpler than heel-and-toe, since you just shift to the exit gear while you're braking into a turn, with clutch disengaged, and then when it's time to apply power, engage clutch again, along with rev matching. This lets you use the brake proportioning valve to match fore/aft braking pressure to each turn on the course.

This weekend's Monaco GP had the Mercedes cars doing single-blip downshift to the exit gear instead of sequentially shifting. This is Monaco, and that's why this technique is so useful. One of the announcers commented on it as well.

Getting back to my skiing analogy: when you're carving a turn at the limit, you want both front and rear edges to be fully engaged without distraction. Imagine if you then flip down a snow brake beside your two rear edges. That will compromise the carving ability of the skis.

Try to remember your physics class.

Huh? Granny shifting? Not double clutching like you should?

Basically, you don't double clutch when you are doing the heel toe dance...

Think back in the days when you were driving FWD Honda cars. The rear end rarely steps out on entry to a turn. That's because the engine is not connected to the rear wheels.

you forgot the part where you turn the steering wheel. I would hate for the title of your next post to be "I wrecked my s2k on Ortega."

Not in gear = not in control. You need the throttle to help balance the chassis through the turn. You don't shift mid-turn, you'll disrupt the balance of the car. Stick to the basics - brake and downshift (heel toe) while you're driving straight (the braking zone) then turn and modulate throttle through the curve and punch it out of the apex. There is no engine braking involved in this process.

Listen to what many have said, go to HPDE and ride with an instructor. It's the best money you will spend. Driving on theory will get you hurt, go learn it the right way.

Oh that's right! I thought it was all about weight transfer and balance, thanks for educating!

Gotta be a troll. No one could seriously be saying all of this.

Let's close this thread, to preserve it for future reference.

I've been very successful on rotating FWD cars on lift of throttle with turn in.
