I love this thread. my go-to post for all wheel related curiosity.
you might consider adding this link, similar to willtheyfit but its a little more dumbed down
(the distance from strut and wheel well in mm made it easy for a genious like me to understand)
I'll re-suggest when my post count is +3k & then the k00l k!dz will think it might be of some use to people who visit this thread for information.
Just to clarify my original point, bro;
Use this calculator to determine the effect of changing your wheel width and offset. First enter your current wheel width and offset. Then enter your new wheel width and offset. Next click the calculate button. It will show the clearance between the inside of the wheel and the strut housing. It will also show how far the outside of the wheel edge will extend or retract. If you reduce the inner clearance too much or push the wheel out too far, the tire might rub or not fit at all. This calculator is for information purposes only and we do not guarantee fitment based on this calculator alone.
Inner Clearance: 10mm less (the inside of the wheel to the strut housing)
Outer Position: extend an extra 28mm (position of the outside edge of the wheel)
Insert your existing wheel and tyre specs, and the desired size, and the outcome is shown on the diagram. Bear in mind most tyre manufacturers vary slighty from the specs, and that it could be dangerous to run tyres on wheels they aren't designed to fit. The strut shown in the diagram is for show only - Don't worry if the wheel looks like it fouls!

willtheyfit is MUCH MORE in depth and informative, I agree. My point is (as i stated before, twice.) the "n00bz" who want to know if it will fit, are going to have a much easier time looking at the first, because it just tells you, it'll ****ing fit, congrats. whereas the second just tells you a bunch of specs that you may or may not understand.
all I was saying, bro
What the hell does post count have to do with any of this? EXPERIENCE has everything to do with this... Bro. If you can't read that calculator and have a generalization on what it's saying, maybe you shouldn't be working on your car...
I didn't bash you for posting something relevant, I said that the other calculator is just as easy to read and it clearly provides MORE useable information that would benefit you in wheel selection.
Try thinking next time before you run your mouth, Bro.
Just for clarification, the strut in the image on willtheyfit.com is not an accurate representation of your strut. It's just there for looks. Best bet is to figure out what the minimum offset of some width wheel is, and base your inset off of that.
ok i've reid the ENTIRE post but... information are fighting each other.... i went to whilltheyfit

I'm currently on Classix, 225/45/17...want to go on 18/8,5 with 245/40/18 and lowering about 1.3 inch... The table a the second page says i'm in between and need ET45, whill the fit say i need ET 35 ....
How am i supose to do to fit that under my GLI ?? I will proabaly got rubbing... But...does a fender rolling job will eliminate it???
^ ET47 or so should sit you right where you need to be to run 245/40s.
You'd be fine at stock height, but rubbing is imminent if you go lower.
Even at stock height though, you'd rub a little from suspension travel.
The lower the offset the further out your wheel is going to stick. If you roll the fenders it will give you a little extra room but I stress the word little. The wheels your looking to run should be just fine, I would just suggest a smaller, less thick tire.

This isn't exactly a thread emphasizing function.
Performance-wise, you'd probably be alright with an 18x8 ET45 using a 235/40 tire as long as you're not low. If you lower the car at all, get a stiff-ish setup and you'll be fine.
I'm not sure if Dan_GSR is on here, but if you're on GolfMKV, send him a PM if you want to find out about a good track setup.
great info to have
i might have a great deal on 18s but with the widths and needing adapters im not sure that they would even fit, any input? specs are 18x8.5 et 35 and 18x9 or 9.5 [not sure] also et 35. bolt pattern is 5x100 so would need adapters.
So I picked up a set of BMW m3 wheels for an absolute steal.
I know BMW's usually have wacky offsets but is there any
chance I'll be ale to make these work? (with 15mm adapters)
Front: 18" x 8", 47mm Offset
Rear: 18" x 9", 26mm Offset
