Did you have to reset the computer to compensate for the larger rims n tires?
One of my renters put some 26" disk wheels on his Ford, and they look like pancakes. Asked him if his speedometer was still correct. He looked kind of funny,,, "Ahh, Never thought of dat"

any tire size swaps should be within a few 10ths of an inch of the same outer diameter, otherwise you'll need to make suspension mods such as changing the camber, caster, and these are non-trivial. if you don't reengineer the suspension/steering to match the wheel size, the car will handle terribly, for instance larger diameter front wheels can make the car very heavy steering.
so like, 17" wheels use 245/45 tires. 18" wheels use 245/40 that are essentially the same diameter but a little wider with a little less sidewall. 19's use a /35 size, and 20's would use a /30 size which would have almost no sidewall at all and be strictly for glassy smooth racetrack or just showing off.

Now that is a great post. Always wondered about those "Big Wheel" players.. When back in the 60-70s it was wide white sidewalls. Never could get mine to balance properly, So, gave them away.

yeah, those have smaller brakes. The 350 and above fit a min 17" wheel.
As far as changing the comfort suspension, the easiest way would be to sell the sport car and find and buy a comfort car. Changing suspension would be quite a lot of work, springs shocks the spacers, the springs are matched to the weight of the car according to the options in it so different comfort cars have different springs. The comfort suspension rides an inch or two taller than the sports suspension.

There was one guy on this forum who said he changed to 16" wheels on an E350 4M, I remember he said he had to rebalance the tires with flatter weights because they were clicking/hitting the caliper! I don't think we ever heard the longer term affects, or if it actually worked out.
