Even one millimeter more on the gas could be the difference between steady state oversteer or spin. Of course this means you have to approach corners with a different strategy.
I would buy some great tires but research their breakaway characteristics through magazine sites e.g. "Grassroots Motorsports" etc. TireRack reviews are okay but I'm focused on your track days and not
daily driving.
"TinyVoices" has some good info.
I would change one thing at a time. Better tires and a change in sizes and sidewalls could leave you wondering what made the difference. Plus we don't know if you track your car in the rain.
Last but not least, what track are you driving? Mont Tremblant? Paul Ricard? Jerez? Kyalami?



Yes I do track at rain also. The track is Istanbul Park

Probably a great idea. Run Flats absolutely stink IMO. As mentioned above smooth is fast on the road course. And good tires give more warning before letting go...

A little off topic but I have to ask, do you get to drive the whole track? I remember watching F1 races on that track, on TV. You will learn many things about your vehicle driving that racecourse. Have fun.
