Default Offset and camber on your 10” rear wheels

Hello all,

As disappointed as I am in myself for posting a thread requesting help with wheel sizes I would like to piece together info.
So currently my Work meisters I had custom made for my m3 are more oriented for a car with shaven fenders. My fronts are fine at 9.5 et26 but my rears at 10.5 et16 are simply too wide to run without more camber than I’d like with my stock body. Im over the whole camber thing and want proper tires.

So I plan to re lip my rears somewhere along the lines of a 9.5 with high teen/ low 20 offset or a 10 et 20ish. But before I make a decision I need help. So for those running a 10 et25, can how much camber are you running with un touched fenders? And a 265-275 tire? Same with 9.5 rears. What Im looking for is about -1.5-2.5 rear camber max. And I don’t want to have to raise my car a ton. Im a big fan of very tight meaty fitment. They are 18s if it helps. I dont want to step down to a 9.5 and need a spacer, but don’t want a 10 that wont fit! Pics and your guys opinions are appreciated!

Default Re: Offset and camber on your 10” rear wheels

A 10" et 25 can comfortably fit a 275/35/18, even lowered, if you've got more than -1.5 of camber. You could even throw a 3mm or 5mm spacer in there if you've got like -2 camber.

I have a 275 (wide PSSs) on a 9.5" et 22 wheel with a 5mm spacer and -1.8 camber and I still have 2mm clearance with no fender modification. Yes, a 10" wheel is 12.7mm wider, but that doesn't matter terribly as the tire is the same and will stretch a bit so, in reality, the difference won't be 12.7mm at the top of the tire even though it is at the rim.

Hope this helps you or others as you probably know some or all of this already.

I'm running what is effective ET28 (ET40 with 12mm spacer) and no problems with stock alignment and a minor drop (13" rear height). Had minor rubbing with 15mm spacers.

We need more info though. What width wheel and what width tire? Also, not all tires are made the same and even within the same brand, there are different width tires in the same class (i.e., 275). Tire rack will give you the real width of a specific tire.

My et is effectively 17, but that's meaningless without the other info. I get away with it because my wheel is 9.5" not 10 or 10.5Some could run et05, but maybe they have a stretched 245 back there on a 9" wheel, if you know what I mean.

Default Re: Offset and camber on your 10” rear wheels

Im running a 19x10.5 et 22 with a 275/30/19. That’s about as far as you wanna go if you have shaved fenders. Im running 1.5-2 degrees of negative camber in the back which is just about optimal. Car is at a resonable ride height, I have it setup to not rub at 10/10ths on bumpy roads. If you dont have shaved fenders 10” wide rims with et23-28 are optimal with a 275.



On the front I have 19x10 et 28 rims with 5mm spacers to clear coilovers and 275/30/19 tires

Hey don't get smart Mirza, you know lurkers won't always make that leap plus that's the wheel width, not the tire which matters too

Awesome information. That was a great help to me. I knew 10 et25 is a very common size but wasn’t sure if those people had shaven fenders or monster truck cars lol. Sounds like I will go with that size. It seems like it will fit like I want. Thank you Tbone!

Looks great. I wish I could find someone in Chicago suburbs who I’d trust to shave my fenders, then I could probably keep them a 10.5. But I don’t know of anyone. Your stance is exactly what I’m looking for. I appreciate the picture too!
