I'm thinking about putting 20's on the back and 19's on the front of my R/T for an old school look. Has anyone tried this, and how will it affect handling, Odometer, ESP? Also planning on lowering, any suggestions?

 

I thought about this as well. As I have always loved that on the old muscle. I am guessing that I will not do this, but eventually lower the whole vehicle with Air Suspension. If you are to do this though, I would suggest getting the Superchip, as I hear it allows you to adjust the rim setting to calibrate your speedo. Going with the bigger wheel in back to keep it lifted you will have to have the same sized tire as you would on the front, or else it will just offset the ride height with a lower profile and you will then defeat the purpose of bigger in the back! You would hate to start getting tickets for speeding because your speedo goes whack! Just at thought.
