Pressures:
205/50 is going to give you quite a high ride. I had 195/50 and used 26 / 28 when cold for track use on Yoko A048Rs. Can't imagine why you'd want to use them on the road to be honest.

how can you control understeering?
learn to drive the car. It understeers I'm afraid.

changing to 205's dramatically increased understeering while using the same tire pressures.
