How's it goin guys? I'm getting ready to start my Z project but I have one question. What is the best offset for fitting 18x8.5 front and 18x10 rear. I know it's kinda big, but I've always gone big on my cars.

 

more and more ppl are goin with 18's on their cars. It's not that big anymore.
Offset should be determined by your dealer. They and the manufacturer should know what will fit your car. That's their job. That's what they specialize in. They better know, if not, time to find a new shop.

 

It's not theshop that is doin the wheels. I'm just lookin for the proper offset for the wheels that I want. The shop is justdoing my motor work, I'm doin my wheels, brakes, and body mods.

 

so,....you're going to buy wheels online. Buy tires online and then mount them yourself?
Either way you look at it, you'll have a shop involved. A 35-40 mm offset should be fine.
