Hey I have a 2008 G Coupe running with the oem 18 inch wheels.. I'm thinking about getting spacers. Can I get 20mm spacers(all around) riding stock height and be fine until I lower later? If this has been talked about link me to it.. Haven't found anything.

 

20mm will put your 18x8 at about a +23 offset, will be fine w/ up to a 245 width tire.
