NO!!! dont do it, you will regret it big time!
you DO NOT want 17" wheels on your n/a.. it probably wouldnt even do 60mph with them installed..
with a car that under-powered, you notice every spec of power you lose..
how CRSMP5 explained it, is about dead on.. let the air out of your tires and go for a drive..
i had a set of 17" wheels on my rabbit for less than 2.5 miles.. i installed them, drove around the loop my house is on, drove it back in the shop, and took them back off. my car even has a turbo, and it still severely affected my acceleration. i was much happier with my acceleration with the 13" stock vw steelies..
if you want to UPGRADE your wheels, get a set of 13, or 14" alloy wheels, and install those..
big wheels are HEAVY..
and where would you find a set of VW oem mags that are 4x100 bolt pattern?
