456GT Display storyboard

Just curious... Have you compared the ride with these wheels to the std. 17 inch 456 rims? I like the design, but I am afraid 345 rear wheels will make my car too noisy..!? Beautiful car! 456s are rare in Rosso Corsa.

 

Ok interesting. Well more area of wheel touching the ground gives less downforce per square inch. In wet and slippery conditions, wide tires is more «interesting» to drive....

 

A quick look at your document shows one thing is wrong. The 'v' angle is 65 degrees. An interesting an odd choice, shared with Dinos. I have read a number of explanations- not sure I am fully convinced by any of them.

Cheers,

Phil

 

Glenn- She should feel very planted with 12.5" rear wheels and 345/30 MPSS tires. Those rear tires are very sensitive to camber. If it is off at all, only a portion of the tire is on the ground, effectively reducing the contact patch and that could easily induce oversteer. Similarly, the tires are very sensitive to tire pressure for the exact same reason. Off a bit and the contact patch decreases. My 575M had NF2s, but with even wider 355/25 Pirellis, and 32-33 psi F&R worked fine. You might have your suspension aligned by a real expert. Easy to do on our V12s, since we have eccentrics for camber adjustment, which unfortunately tend to get out of alignment quicker than the shims used on other Ferraris.

 

Glenn- Overinflated has you running only on the center of the tire, and that would explain the oversteer.

 

Lovely car and colour combination.
