Already stated above.

I'm want to go 18 or 19 x 10 also.

What square offset are we talking about? spacer needed?

OEM ZCP 19 x 10 is et25

As I stated above, if you run 275's with KW coilovers on those wheels you will need at least a 5mm spacer which yeilds an effective et20. Success will depend on which tire brand you choose. I have found that I needed et18 to fit 275mm Michelin PSS on 18x10 wheels. I have noticed that some people have had success with 18x10 et20 using Hankook RS3's in 275/35/18 sizing. It all depends on where your coilover spring perch sits relative to the tire (ride height and 18" vs 19" wheels will impact this interface). If I were to spec a custom 10" wheel for someone with KW clubsports or V3's I would go with et17.

Now... If you have OEM suspension, lowering springs, or a coilover system that does NOT reduce inner clearance, then 18x10 et25 will work with 275's. See the link below; I modified my KW clubsports to allow fitment of 10" et25 wheels.

Edit - I should also add that those who run 275's on 10" wheels should be prepared to add negative camber. You might be able to get by with stock camber settings with a 10" et25 wheel and conservative 275mm tires. More aggressive tires (ie tires that run square and wide), and/or a more aggressive offset (lower than et25) will likely require negative camber. I typically run around -2.0 on the street with very good results.
