what are the advantage and disadvantage of these sizes?

i'll been looking for a steering wheel. The Spoon one has a 360mm diameter, where there's a momo monte carlo at 350mm.. I know both doesn't make a big different, but what if i go smaller to like a 320mm?

are the bigger wheels for precise? if i want to go autox, street driving, and (may be trackdays) what size is more suitable for me?

Also, is the spoon steering wheel the same as the momo monte carlo? Is there red stitching model for the monte carlo?

thanks, help appreciated

 

Wheel size will determine the effort required to steer the car. Smaller wheel (lever)= more effort. Power steering minimizes the effect, though. A smaller wheel will also allow 'faster' steering changes than a larger wheel because less relative movement around the axis of the hub is need for the same result. The difference is probably minor enough that looks are the main reason for changing.

 

how about weight? does it make a difference?
