A fantastic question fellow 'Cuda friend!
I am also considering 17" wheels for my 'Cuda, and have searched a couple sites and taken some notes. My next task is to photoshop each of these on my 'Cuda, but I haven't had the few hours to spare, and with our computer severly on the fritz after getting some bad spyware infections, it's really not up to the task right now.
But I'll give you the list if you'd like to look into them, and you can scan TireRack and DiscountTireDirect.com to see how they look.
Searching in 5-114.3 x 17" (any widths)
MB Wheels - Predator
Replica Alloys - GT500 Mustang
Ace - Radium
Konig - Beyond
Konig - Stampede
TSW - Vortex
Granite Alloy - GA4.5
Koda - MD3
Koda - 215
MSW Wheel Effect - Type 12
P.S. Alright I got bored and just pulled the images down for ya. So since I did that for you, you can photoshop them for me.
lol
Jeff
**EDIT** Ya know looking over those again, those Type 12's at the bottom are really really growing on me...
