I'm about to pick up a set of coupe 18s for my sedan and i was wondering what tire size you would recomend to get, I'm on coupe tanabe df210 springs, so about 2.2R and 1.8F.
If its possible to make them sit sortaflush or just have an agressive look what would i need to do? Spacers?

They'll fit really well as far as being flush. If you want to get more aggressive I would wrap them in 235/40 F and 245/40 R, mount the wheels, and measure the gap. you might be able to get away with a 5-10mm spacer both ends with rolled fenders and a little more camber.
