Look mang.. It simple, some of the weenies around here like to bash on anyone wanting to hook up a nice set of wheels. Half of them run their stock 15" wheels and thats all well and good for these lads but you know what, if you wanna roll and look good then heck, loosing a MPG or two aint gonna hurt ya. Either way my 17" Miglias make little difference compared to the hit I take on my milage thanks to my heavy foot. Maybe they can make me a right leg out of "beryllium".. ?? Best bet is to go with a light wheel that you like, the Aristos off the GTI would look mint.
Bilstein PSS9 coils are the way to go with full adjustibility across the board, something I would have gone with if it weren't for the $$, I'm running on the FK Coils and love them.
To finish the rear sway is a great addition to improve the handling but I have heard nothing but dissapointment from people who have upgraded to an aftermarket front sway and more often then not they go back to the stock sway. At worst if you plan to drop enough to hit the sway bar then opting for longer endlinks could help. The front sway is a ***** job on the MKIV platform..
Now marvel at this TDI's 19" of wheel goodness..
