Dont know what size spacers to go with?? i have 18x10 +25 all around. i want to be flush all around?

 

People will need your tire sizes, what you are dropped on, what kind of camber you are going to run, fenders rolled/pulled.

 

225/50 F 255/45 R dropped on H&R springs. No fenders rolled/pulled.

 

damn those are some bad tire sizes. You shouldve gone with 245/40 front and 275/40 rear, or did you use the stock tires with your aftermarket wheels??

To answer your question I would go with a 10mm spacer also if you post pics of your car it'll give us a better idea on what to recommend
