355 Fiorano Handling Package Vs Challenge Suspension ECU.

I’m going to use this Serie Fiorano as an example.

Front height is set at roughly 10-15 threads up. According to my calculations, rake is either Omm or the car is higher in the front vs rear. My guess is alot of understeer is dialed in with this setup.


Serie Fiorano owners should consider getting an alignment shop to setup up the car if he wishes to have the full factory recommended experience.

Here is an FHP car (left) vs standard car (right). It appears owners are leaving the rear height untouched while raising the fronts. Standard 355’s can simply raise rear (to 191mm) to improve rake. FHP 355’s only have a small window of adjustments if one wishes to keep factory settings.
