Anything else needed?
 

I have 17x9 +42 rota grids and bc coilovers sitting in my garage waiting for winter to end. Just wondering if I'm gonna need spacers or anything else with this set up. Tire suggestions also would be great. thanks!

I headed into the stickied Wheel Directory topic and searched '17x9.0 +42' and found three other cars running the exact same spec wheels. You should read these topics and if you have questions you can ask one of those owners.

You're going to need some rear LCA's/whiteline camber bolts as well.
