    I have a (USA) 1978 308GTS that I recently replaced the wheels with 16 inch ones (from Superperformance). I remember that the 16 inch wheels were optional but only 14 inch ones were brought into the USA with the cars. In the owners manual, it gives the suspension settings. I want to know what different settings should be used for the 16 inch wheels. This is a street car, so I am not interested in a track setup.

    There is a great deal of difference between the construction - and likely performance, between old metric wheel/tires and newer tires on 16 inch rims.

    So, this is a wild ass guess.

    Going from 14 to 16 inch wheels and tires, i think the primary consideration would be the tires camber. Generally, lower profile tires are less forgiving of camber because they are more rectangular and have less compliance.

    If the car is at stock height, i am guesing that Ferrari engineered the camber to go gradually into negative with bump. so if you are running stock springs at the stock height, go with stock, or a bit more upright specs and depart from stock after seeing how the tires wear, or if you drive it hard, most shops would tell you to go with a bit more negative camber, sacrificeing wear for grip.

    I would be more concerned with the tire choice. How much grip do you want to pay for??? STicky, short lived tires cost, but they corner so hard it makes your fillings hurt, may not last a year but they point the car immediately and stop quicker than the run of the mill all season tire.

    Hope this helps,
    chris
