Hello All...Decided to keep the Rials...
I like them too much to sell them.
To answer questions though the lips are roughly 2.25" front and 3.75" rear.
Ride quality is obviously more stiff than stock, but honestly they ride great and have a smooth feeling, I highly recommend the Falken 542's with 20" wheels they work nicely. I had the M5 in the mountains recently and was very impressed with the handling/performance for a 20" wheel.
