If I put 20" in rear and 19" up front will there any big difference on handing? What tires can I use? Anyone did this? Who makes this kind of wheel sizes? I don't have a plan of tracking my baby just for show. Any ideas? Pros and Cons... I saw some who had Purner 505's but both are 19". Just trying to fill the gap on the rear. And how much I can get on my stock wheels if any?Thanks for any input.
