Rims and offsets Options

[-JR-]

I've seen lots of posts on rim sizes and tires but none of them seem to include offsets.

Can anyone point me at a post that covers 914 rims and offsets?

I've got a line on some 16" Fuchs with 8" and 9" widths. This is pretty close to the maximum width a GT can accept from what I've read.

The rims I'm interested in have an offset of 10.6" front and 15" rear.
No idea what these came from, but I'm guessing some kind of 911 based on the other parts for sale.

Any feedback would be appreciated!

Thanks!

It depends on where you want the wheel positioned in the wheel well.

Ive been trying to work out the math on this as well while i wait for my car to come back from metal work but im waiting until i can physically meassure the completed fenders before pulling the trigger on new wheels.

What I currently know though is:
16x7 ET35 wheels running 215 width tires is about as far inboard as the wheel can sit without the tire rubbing on the inside. We are talking a millimeter or two from rubbing on the front strut cover, So close that when i had a tire running low pressure at an autocross the extra flex was enough to rub paint off the strut cover.

From there you should be able to scale it outward in theory. As an 8" wide wheel at the same offset would sit 1/2" more inboard an 8" ET23 would be about as far inboard as you could go (ET23 I believe is he most inboard that most 911 wheels would be) For a 9" wheel then this would be around ET10.


BUT that is just on the inboard side. Reason i have not pulled the trigger on the wheels yet is i need top physically measure how much space is available on the outboard side of the completed fenders. Im looking to center the 9" in the rear to allow for as wide tires as possible for autocross purposes but others looks to run it as far outboard as possible for the flush look. Depending on the flares (assuming regular GT flares) you probably have somewhere between 10-11" in the rear so my Guess is for the 9" that anywhere between +ET10 to -ET10(though likely more) should be safe but i need to physically measure this.

My current plan is around 8" ET20 in the front to keep the wheel as far inboard as possible for handling and ~ET0 in the rear for max width. As this is my autocross car appearance is secondary.

Also note this is with a stock 4 bolt setup. not sure if the 911 brake conversion changes the offset.

I also have my car setup for max camber
