Just read through this, it will help you immensely with wheel fitment.

As far as coilovers go, if you're just trying to give the car a good stance then the Megan's will probably do just fine. Buddyclub n+ are decent as well. I run apexi n1 coilovers for reference.

 

If by stance you mean-3 camber and more do front and rear adj ball joints. Then come alignment time you can get it looking how you want. Key will be going to a performance shop who knows how to get the alignment you want. I think it's strange you want "stance" yet went 255 square.
