Hi guys
I have a set of bbs RS 003 16 X 7 et 25 I belive

I wanted to change the lips to 2'' and 1.5''

So would they now become 16 x 7.5 and 16 x 8?
And what would the ET now become, Can someone please explain.
Thanking you kindly

7.5 will be ET 18.7
8 will be ET12.3

when you widen the lip, the center mover to the inside

1" wider is 25.4mm which is 12.7 if you look from the center then you get 25-12.7 that makes it 12.3

RS003 have 2 inch lips to begin with.

handy for figuring them out in future. inner clearance stays the same when youre just changing lips.
