or RWD....

AWD is unstoppable. just floor it. you have way more traction then RWD or FWD. AWD >>> fysics, FTW!!

 

^^^ No, it would be the opposite correction for a RWD car - More gas to correct understeer, less gas to correct oversteer.

Left foot braking is key to getting a turbo AWD car to be very fast. Plenty of rotation and keeps the turbo spooled up and on power. I just had a long conversation about this with instructors at mid-ohio (NASA Nationals) and the fastlane school. These recommendations are based on data acquisition analysis.

 

huh? Adding gas to correct an undsteer is not a good idea. Letting up on the gas will cause the back to rotate correcting your undsteer. If you are oversteering less gas will cause the back to unweight and exacerbate, not correct, the problem. If you are oversteering because you hammered it from stand-still fine, but if you are oversteering in the middle of a corner at near 10/10's you need to keep on the gas and try to turn into the slide if possible. Letting off the gas when you start to oversteer in a corner usually spells disaster no matter which wheels your car is driving.

 

and you shift-down while braking how??? are you talking about left foot braking in corner?

 

Well, when I'm understeering in a corner with the S, I add gas to bring the car around, but this is with my current tires. Letting up on the gas would put more weight on the fronts and lift the back, but I'm not sure I want that because of loss of traction in the rear. When I corner its usually understeer in to oversteer out, but I'm no expert.

If you are understeering in a corner, then you have already exceeded "10/10ths." You've already exceded the available front grip by entering the turn with too much momentum. So by definition of 10/10ths as the absolute limit of the car, you are at 11/10ths or 15/10ths or whatever you want to call it as the car understeers. The front tires are already sliding wide, and at that point, if you want them to tuck IN, the way to achieve that is to step on the gas in a RWD car.

If you are oversteering in a corner, then you have also already exceeded "10/10ths." You've already exceded the available rear grip in the corner by feeding in too much gas to the point where you have broken rear traction. The rear tires are already sliding wide, and at that point, if you want to catch the rear end before you end up going for a loop, the way to achieve that in a RWD car is to ease off the gas, and possibly feed in some countersteer if needed.

But what do I know? I'm just an SCCA Solo2 instructor...

OK, let's just stick with this. If the front tires have exceeded their grip levels and the rears haven't how does adding gas (assuming this does not exceed the grip of the rear tires in a RWD car), which will add more speed to car, somehow make the front tires grip?

If you can add enough power to rotate the car around sliding front tires, more power to you, but that's not common. If the front tires are sliding and you add more momentum to the vehicle how are they going to start gripping?

 

I'll just say that with my STi I felt it had amazing grip when I would accelerate when entering the turn, the car just hunkers down and pulls through the turns great.
