There have been a overwhelming amount of threads created asking if a certain size wheel will fit their MK5. I decided to create this thread hoping it will be stickied at the top of the MK5 Forum!
#1 - The only link you will need
THE WHEEL OFFSET CALCULATOR
You will be using THE WHEEL CALCULATOR to figure out how much a wheel will poke out compared to your stock wheels.
#2 - Official Specifications of stock wheels
GLI/GTI stock Ronal 17" - 17x7 ET54
Monza/Detroit/Hufweisen BBS 18" - 18 x 7.5 ET51
Karthoum 18" - 18 x 8 ET50
#3 Using THE WHEEL CALCULATOR
Go to THE WHEEL CALCULATOR link above.
Once you are there, you will see where you can input your CURRENT WHEEL SPECS along with the NEW WHEELS SPECS (the wheels are you looking to buy)
Input these two specs and hit the CALCULATE button.
Once you hit the CALCULATE button, you will have two different measurements below...
INNER CLEARANCE and OUTER CLEARANCE
INNER CLEARANCE means the clearance you will have between the inside of the wheel and your shock/strut.
OUTER CLEARANCE means the amount the wheel will poke (or not poke) compared to the wheels that are currently on your vehicle.
#4 EXAMPLE
Let's say you have a GLI with the stock 17 inch Ronal wheels.
The specs of those wheels are 17x7 ET54
Lets say I want to put a wheel on the car that has specs of 18 x 8 ET35
Input both specs into THE WHEEL CALCULATOR and we get the following:
INNER CLEARANCE = 6mm MORE CLEARANCE meaning you have have 6mm MORE space between the shock/strut and the inside of the wheel.
OUTER CLEARANCE = EXTEND AND EXTRA 32mm meaning that the wheel will poke out 32mm MORE than the stock 17 inch Ronal wheels.
Here is a picture of an 18 x 8 ET35 wheel installed on a GLI/Jetta running 225/40/18 tires...

And there you have it. You just figured out how much a wheel will poke compared to the stock 17 inch Ronal wheel that comes on the GLI.
Have a nice day!
MODS, DO YOU THINK WE COULD GET THIS STICKIED AT THE TOP OF THE MK5 FORUM???????

i also submit this link:
http://www.net-comber.com/tirecalc.html
it calculates actual vehicle speed vs what the speedometer reads when changing wheels.
has nothing to do with inner and outer clearances.
for that, i use the 1010 wheel offset calculator.
edit: the link above also calculates different wheel+tire heights compared to oem figures.
