FTO Wheel Donut

I’m interested since I have GTO wheels

 

Apologies if this is a dumb question, but what are you looking to install?

Taking wheels and discs off is a trivial task; call it 5 mins for a wheel and 10 for the 10 disc. If that.

 

Looks like something that is going to act to restrict airflow onto the brake disc. I'm struggling to see the benefits. Are these used in motorsport? I don't think any OEM's use them on their street cars.

 

^^ That is standard fitment on the GTO. Ferrari would not have added it if it did not provide some benefit.

To the OP look at the parts diagram for the parts required. From my understanding you do not need to remove the rotor.

 

Fair enough! I'm a natural skeptic. I still am really given they don't seem to be something that's taken off in the industry. Still, I guess they complete the look.

Installing will be more work than just taking the disc off though - looking at the below, I can see the donut carriers attach using the hub-bearing bolts. These are on the back of the bearing - bit awkward to get at by the looks of things, and might be a pest if the bolts decide not to play nicely.

Robin- Looks like they are designed to work in conjunction with the air deflectors on the front suspension (5 above), which are also present on the 599 GTB.

 

I have also looked at these for installation on 599 with GTO wheels. It doesn't look like a big deal to install, but it must be with GTO wheels.

 

I don't believe GTO wheels specifically are critical - all you need is the clearance inside the rim for the donut.

What I would think is more critical if you want the functionality, is the GTO bumper / brake ducting.
