I have a 82 gs. It has 4x110 bolt pattern. Uses lug bolts. I have bought studs to eliminate that. I also bought 4x110 to 4x100, 1" adapters to fit any honda/miata wheels. A lot cheaper and easier to find. I came up on some brand new 15x8+0 enkei apache II. 195/45 tires. With a offset like that. I was thinking of fender flares. But idk which ones to get. I hear there are different sizes. Im kinda lost in how about doing this.

 

I look up on eBay, zg fender flares. Or I think the generic Miata ones work as well. Good luck!
