Which 20's To Buy

[CMYZ66]

I am looking at getting a set of 20's for my AV. I have narrowed it down to 2 wheels. One is the Enkei RT6 and the other is MB Motoring Propellor
You can see them at http://www.discounttire.com/dtc/fin...EL&sortOrder=Price&wheelRimSize=20&plusSize=3


Also, I am going with 305/50/20 for the tire size. Will that change the height of my Av?

Thanks
