Hi everyone first post here and was looking for some advice. I have a 2010 g37s sedan and i want to put the 19in coupe rims on it. From what i read the look is a little weird if you do not tweak the suspension, but i wouldn't mind changing out the suspension for a better/lower ride. With these rims would i need to get the staggered or the normal ones? Would wheel spacers be necessary? Whats the best suspension tweak for a low budget?All in all i would like to spend as little as possible not including the rims/tires. Any advice or pictures would be helpful, thanks.

 

Welcome to the site!
You could get the staggered set since it's much more common and just run 245/40/19 tires all around, the stagger is only a 1/2" so it's no big deal running the same tires all around.
It looks OK at stock height but better w/ a drop. The lowest cost drop is a mild spring drop like Eibach, and a rear camber bolt/toe bolt kit. The springs cost about $250 and the 4 bolt camber kit (you need two kits) runs about $50. If you DIY the install it will run about $300 + alignment (which is about $125).

Tein Basis coilovers are about $600 so add that rear kit and you're out about $650 + alignment if you DIY then install, and with coilovers you can set the exact height that you want.
If you're not one to wrench on your car then figure about $300 for the install give or take.
