Hello people!

Anyone here done this yet? I am planning to adjust the factory coil overs to get better center gravity and get rid of the wheel gap. Will you scrape everywhere? Cali is pretty low already imo.

 

I don't have a Ferrari but I have lowered 4 cars.

There is always going to be the need for increased road awareness with a lowered car. A Ferrari is already a low car so you shouldn't go too low. One inch should be fine for improved looks and handling. One inch won't cause much of an issue with potholes, speedbumps and dips.
My first try I went 2 inches and had the worst experience of my life since I enjoy spirited driving.
Since then it's been 1 inch and I have mostly trouble-free motoring.
