How much lower?!?!

There's a reason why the VW mega-culture still prefer the smaller diameter wheels over the DUB scene.. and that is creating the ultimate low stance. Let's look at the facts, 17" inch wheel is automatically 2" lower than rolling a 19". Plus the suspension geometry automatically pulls more negative camber when slammed, thus gives a very low body line.

This Phat-ASS IS300 example was sourced from Canibeat and is rocking staggered 17x9.5 "OG" BBS RS wheels front/rear.

Good job kid!
