Offset question
 
I am trying to see if a set of rims will fit my car am i doing the calculations right?
Im just worrying about the rears right now
I currently have a set of turbo rims so 7 inch wide with a +40 offset
these are 11.5 inch wide with a -13 offset

so will these stick out 109.25mm from the current rims i have.
and will go in 3.25 mm

also alot of ppl strectch there tires the only benefit this will give me is that the tire wont bulge out anymore right?

also what cars have lower offsets and rather wide rims?

I know mustang cobra wheels are +24 9 inch wide...any other makes that need to carry a similar of wider and lower offset wheel?

That 11.5", -13 will clear the insides.
No way in hell it'll stay under the stock fenders - I hope you got plans for big fender flares?

It's for cheap people who can't afford the right size tire widths.
I'm not a big fan of hipari...

I know it wont stick under the stock fenders. My question was how much it would stick out from the stock tire, i have the stock tire on and want to see were this one will end up.

and i know i need fender flares, my car already has a custom widebody kit, but i think these will stick out 10mm from the kit

I can easily say it's going to be at least 2" or 50mm.
I think it's actually more...

Just to run the numbers...
8" wide, +50 is an FD rim - this has easily 2" of spacer from fender lip.
You're running 3.5" more width and just about 2.5" difference in backspacing.
3.5" / 2 + 2.5" = more than 4"!
I think I can safely say it's going to be close to 3" at least.
