my goal for my car is, autox/ track car I wanna keep the stock wheels but with cheap Daily drive tires, and then get a set of rims and tires which i can switch out to autox on, I've been looking at a few wanted a light rim liked the look of the Work emotion wheels but didn't specs on it. Wanted also to stick near a gold/ bronze look on the rims have a black car.

Questions

2. and what size tires should i stick to? stock 235/45/17 for the new wheels?
3. And any websites that I could look at for details on wheels and tires
4. Would i need any wheel spacers, and what kinda offset do i need to stay around basically needed schooling on wheels
