I am thinkin throw some 20 + inch chrome Iroc rims on my 92 camaro, because my Camaro currently sits on some scuffed up bullshit 1984 Z28 wheels

, i hate my 15by7 wheels they are too small. I wona throw some big wheels on my ride, i found some 22" Irocs for a good price, so will it fit my Camaro or it will rub on my wheel wells, and will it thorow my speedometer reading off? Or should i just stay with 20's?
