Hmmm? Sorry not sure Rod, it'd be disappointing if you specifically wanted net 13 and they bolted up zero offset. In reality though now tha they are on the car do they sit how you want them to sit?

I went 16x8 in a neg6 and am very happy there but would go a neg 13 if I ever did it again probably,

Don't be lazy check your spare or get a tyre rotation done and ask them to slip the tyre calipers over the rim while it's off the car.
