Thanks for everyone's input. Had to replace the brakes and tires on my car so had to decide on wheels fast and couldn't wait. So back to the 214's for me. I do like the 336's, but they just look slightly more difficult to wash.

Have 4 x 21" 128's up for sale now. If anyone is interested, PM me. Looking for local sale only. Wheels are located at dealership in Orange County.
