I advise you align the tips with the outer edge of the diffuser. Gotta love the AA design.
Regarding wheels decide on budget, level of performance (weight and size), and maintenance commitment (3 piece and complicated designs require a lot upkeep)
You can't go wrong with a simple 19 inch, will look good, is within OEM parameters and will weigh less then the equivalent 20 inch wheel.
Design is a personal thing really, what wheels have you been considering?
