Wheel Fitment Question Thread

[Happytimetom]

Hey guys, first of all I understand this is a silvia forum however it's the only place ive found so far on the net where people seem to have a clue.
I have a Toyota 86 arriving in October and i'm looking at buying some wheels before it arrives. I have taken a liking to black 18" xxr 521's.

However i'm not sure how to get a nice fit (flush with the guards) I wont have coilovers so i will not be able to adjust ride height or camber, I just want some nice looking wheels that fit nicely and still be able to drive the car like it's designed to be driven.

Can anyone suggest how I can calculate the right tyres and wheels for me?

Also do you recommend getting them staggered? eg Wider at the back...

Thanks for any help
