Wheel upgrade

[ernieram6]

Hello all, I'm going to be purchasing new wheels and tires. But I need help on picking out the correct sizes and the correct offset. I want the wheels and tires to be flush to the fenders. I'm also going to drop the car 1". This is my wish list
Front 265/35R20 Wheel 9"
Rear 305/30R20 Wheel 10.5" or 11"
Please if any one can help me out or have some advise I would appreciate it. Here are some current pictures.
NONE XDRIVE.

There are lots of threads here if you run some searches. Search words like "spacers" and "flush" and you'll find plenty to read. But mostly I'm responding to say you left out one important fact - is your car XDrive or not? If it's XDrive you need to pay much more attention to overall diameter between the front and back. I'm not sure how the math works out on the tires you listed.

Opie55 thank you for the information and the quick reply. I will definitely search for those key words. My 640 is not an XDrive.

Here I compare 1 piece 2 piece and 3 piece wheels and their offsets. Go into a bit about the fitment and how to get your wheels fitting right. Cover some of the cosmetic, build, and weight differences and giving a fairly easy way to understand offset.

AG F435 3 Piece
F
9.0 et37
R
11.0 et42

BC Forged HC-S03
F
9.0 et25
R
10.5 et38

Azad AZ23
F
9.0 et35
R

Start at 12:00 unless you really want to understand about offsets

forgive the shameless plug.. but please subscribe if you haven't done so!

DerBosewicht, love the video and how you explained everything. Question, why didn't you keep the existing offset of the wheels you took off and bought the new wheel with the same offset instead of putting spacers to flush out the new wheels?.
The set up is pretty bad ass. I ended up purchasing BC Forged HCA384 Polished edge and Polished Champagne Bronze insert.
F
9.0
R
10.5
The Rep is going to call me to talk about the offset.
Thanks again!
