Lot of people around here dont believe in putting blingy stuff on a mustang. You lose alot of traction with 20's so if you plan on getting power mods your basicly defeating the purpose of them.. But if you dont care as much about speed then go for it Some 20" black chrome deep dish with the chrome lip would be sooooo nice
Don't be an ass. 20" wheels will slow you down big time, not to mention busting up your suspension. It will destroy your car. Those big wheels added reluctance to spin is equal to 4 times their actual weight. Do you want that much unsprung weight on your unit? Plus it throughs off your final drive ratio, making it taller, thus slower. It will also throw off the rotational enertia, taking another bite out of acceleration. Your cornering and braking will suffer. Go ahead.
