513m rims - is the concave depth of the front and rear rims the same?

[nakedpants]

Hi,

I was wondering if the concave face depth of both front and rear 513m rims is the same?

Usually the concave face is deeper if the rim is wider (e.g. CSL rims).

However despite the rear rims being 1" wider they have +11 more ET (ET40) so the concave face should only be 1.7mm deeper if at all compared to the front rim.

Can anyone enlighten me?

Yep the back = 17mm more concave

Do you mean 17mm or 1.7mm? If my calculations are right it should be 1.7mm deeper if at all.

Yes I am using the same calculator. Thanks for the link.

Could someone of you guys be so kind and just measure your wheels?

You would need to measure the distance (marked green) like you can see in the picture below.

I was offered a set of 4x 17x9 and would only consider these if the concave face is the same depth on the 9" and 10" rims.

So you would really help me out here.

Thanks.
