Don't go nuts on your wheel calibration settings just yet. The Octavia has a "steering assist" setting that appears to regulate the power steering but also multiply input. If you're having problems with oversteer, just crank that down a few ticks and see what happens.

But as Mike said, your best bet for controlling the snap-oversteer behavior is to make sure you separate your braking from your turning. All the weight in this car is up in the front, so when you hit the brakes, it takes all the effective weight off the rear tires, and leaves you vulnerable to a snap spin. (If you've ever raced a '90s Honda Civic or CRX in real life, it's much the same effect.) Brake for the corner, then turn in, then accelerate out to smash the weight toward the back and equalize the handling of the car. Brands Hatch is a great "first track" for this car because of its flow; it will reward you when you get it right, but instantly punish you when you get it wrong.
