i'm looking into getting new 20"s and some lowering springs for my new magnum r/t. any issues i need to be concerned about? what kind of springs do you guys suggest? how much drop can i have with 20"s? any info is appreciated!!
If you change to 20's and keep the overall tire diameter the same, then the effect of the drop would be same as with 18's. The width of the new tires will be more important, but 8.5 rims should cause no problems. Some have dropped with 9's and say it worked OK. Beyond that, it starts to get tight.
