Make good on that statement to start going to DEs. It's a far more fun place to play with the car than the street - DEs come with a good driver riding shotgun keeping you out of trouble or teaching you new skills, and many track corners have excellent runoff if your fun goes awry. Public roads have other cars, pedestrians, curbs, guardrails, trees, cops, etc - nothing but worries.

i think wayner made a good point. Too much understeer, and you might dial in way too much steering while under power, and when you change throttle position and the front grabs and / or the rear lets go, the car goes sideways in a hurry.

Another factor to consider:

It was a right hand turn, correct?

Did you just fill the gas tank?

Your filler is on the right front fender. Any overspill can end up meeting the road right where the rear tire wants to be.

Everyone jumps to the lift throttle oversteer tendencies of these cars and blames that dynamic alone. There are other factors that can come into play.

Bergmeister states my under steer situation better than I did.

Btw, I've had the same understeer spin thing happen in a well balanced formula car on cold tires. Scrubbing into a turn they gained heat, got sticky before the rears did, and weeeeee!

Glad I was on a nice safe track to learn that lesson.

I'm also glad I learned the dynamics of an early 911 with an instructor beside me, because I didn't know what I didn't know, but I learned in a controlled environment, and after each session analyzed everything the car was doing
