Got my hands on a set of Leon Hardiritt Bugel 3 Pc wheels , gonna be fitting them in a coupe, I’m pretty low on coilovers ,
wheels specs are
F :19x9 + 36
R : 19x10 + 46
looking for nice flush result , or best possible lol

 

For a flush fit you'll need spacers, but you'll be able to run plenty of tire. 15mm should get you there and you could run 255/40 front 285/35 rear.
Best to get tires first then see exactly how much spacing you want.

 

Just to be clear, you don't have AWD? If yes, you need a square setup, and I don't have the knowledge yet to do so with different tire widths

 

You don't need a square set-up on AWD but you do need to know how or where to calculate tire parameters to meet the limitations.

 

I guess what I meant was same outside diameter needs to match front to back. true square? No... but you get it
