under steer

So i have searched & read a lot of threads about the rear ending rear wheel drive layout of the 996. People concerned with the rear end whipping out.. and i have experienced some of that before. Tonight however was something different... under steer.

coming into a corner, i keep my foot on the gas since want to keep traction on the rear so it doesnt slide out, but instead i feel the entire car move diagionally, the front has lost traction & i am just plowing the front (turned) wheels forward with the rear wheels. Luckily the front tires caught traction & i recovered, but it was scary.

Im confused because i thought the 996 was prone to over steer.
my car does not have PSM, last time i entered a turn hard, my rear broke loose & came around a little bit... this time the front, i dont get it.

Difference between the 2 times is that the time w/ oversteer, i had narrower Kumho tires all around. The time i had over steer, i had wider Michelin PS2's on... does that make a difference?

They are prone to throttle-lift oversteer, but it's not a general characteristic of the car...esp if you're slow-in, fast-out as once you get back to the gas and transfer weight to the rear of the car there's not enough front tire or mass for the front to stick...however get back to the gas strong and then lift suddenly and you will see a world of oversteer!

To really drive a 996 fast (on a track) you need to trail brake nearly to apex to keep the front planted and then make a smooth transition back to the power to not un-stick the front while still getting a good drive out of the corner...basically make sure it's pretty well pointed where you want it prior to getting back to the gas really hard.
