Determine offset
Can someone teach me how to calculate offsets? Such as I have wheels that are ET43 offset and I want to determine what spacers I need to make the wheels work. The Wheels are 18X10 on all 4 corners.

So do you need the offset that will fit your M3? Obviously you are gonna need spaces.
It also depends how far out you want the wheel to be and the look you want. ET43 is not a good starting point, that is a 335 wheel or something like that. You need ET20 at least. |

I purchased 18mm spacers. Didn't want to mount the tires on the wheels until I knew for sure the wheels would fit with spacers.
Wonder if 15mm in the rear and 10mm in the front would work?

15mm front & 10mm rear would not nearly be enough. A 20mm offset in the rear, and a 25mm offset in the front would look pretty good.

Two Wheels or Four?

The OEM wheels are +29F and +23R. Yours are +43, so you'd need +14F and +20R just to match OEM. On top of that many people like to go out +10 or more from OEM...so you're looking at +24 and +30 to get the "filled" look. Way too much, I don't know if anyone makes spacers that big...

Looks Like I purchased the wrong wheel. I wanted a track wheel and really liked the look of the D-Force LTW5 wheels. Purchased them in 18x10 for all 4 corners and brought 18mm spacers.
Guess they don't make the D-Force wheel in a M3 offset yet.

"Ideal" offset is far from a fixed quantity. It depends on many factors:
1. Do you ever get mud on your wheels (unlikely in most M3s but not out of the question)? 2. Do you ever run chains (again unlikely)? 3. What wheel width do you have stock or wider? 4. What appearance do you prefer for your car? (somewhat in reverse order of importance) |

What I have determined is that they will work with 18mm spacers however I will not be able to push out the rear wheels out. Also with 18mm I will be running near stock offset and wont be very flush. Running 18mm spacers on a track scare me a little because I have never ran spacer on a track Appearance really doesn't matter due to being track wheels and tires. Will I notice a performance difference between having the wheels flush with the fenders? I don think so. I will notice the difference with having 18x10 on all for corners!
