Just joined up and I want to add some upgrades ....first on the list is to get some new wheels. I've done reading and can't make up my mind as to what size wheels. Wsa thinking about 20" but was told that that will affect my ride...meaning that it will be more of a rougher ride. I guess the sacrifice is whether I want the street looks versus a smoother ride. Also I am worried about affecting the speedometer and/or rubbing. Can anyone give me some input...so I can make up my mind to go 18", 19" or 20"?
