wheel offset calculation question

[_Shane_]

My current wheels specs which are fitted to supra with the wide arch bn kit are as follows

 

Front wheels

 

18 x 10.5J

 

+ 15 F

 

Rears

 

18 x 12.0J

 

+ 9 E

 

I was looking at a new set of wheels with the following specs

 

Front wheels

 

18x9 et -14

 

Rear

 

18x10 et -15

 

My concern here is will these will wheels be further under the arches etc I dont know how to calculate this stuff so said i would ask on here

 

Ideally the fitment of my current wheels is spot on in my opinion and i would like if the new wheels would fit the same on under the arches and wings etc

 

Thanks in advance

Here's a great calculator. Hope this helps...

Basically (0) offset is the centre of wheel=face of hub

Anything + is where the wheel sinks under the arch and hub gets closer to the face of the wheel, (less poke)

And anything - means the wheel sticks out further away from the hub face (more poke)

 

Hope this helps

I use this

The REAR wheels Compared to your existing wheel, this new wheel will have an inner rim which is 49.4mm further away from the suspension strut. The outer rim will poke out 1.4mm less than before.

 

The FRONT wheels Compared to your existing wheel, this new wheel will have an inner rim which is 48.1mm further away from the suspension strut. The outer rim will poke out 10mm more than before.

BTW they are very nice wheels you are looking at, I saw them and wished they had Positive offsets
