wider wheels on 2006 scaglietti advice

Hello, I am buying my first Ferrari - It's a 2006 Scaglietti with HGTC package. It comes with the Ball Polished Chrome Rims. I prefer the the wheels on the Novitec-Rosso Line. They are called NF2.

NF-2
19x9.0 w/ 275/35-19 Pirelli
20x12.5 w/ 335/30-20 Pirelli

I probably wont be track-ing the car but performance is still very important to me. The way the car looks is also important to me and the wheel package fits the bill.

Any issues with doing this. Any advice or comments would be greatly appreciated.

Thank you
