Anyone using rear wheel spacers to give more aggressive look?

[ut_cougar]

i want to add spacers to my wheels since i might not be buying new ones anymore...anyone know a good size spacer to run on an 02 box S with the 18" turbo wheels? I have no experience with spacers at all. What should i put on the front? rear? i want it for aesthetics, a nice look. you said 15mm looks the best but that sounds a bit big? plus i'm worried about what this guy below is saying, how it might pronounce the wheel gap instead of make it look less?

I'm a bit confused by the talk of wheel bearing failure due to wheel spacers. Wouldn't having the same wheels but with the "correct" offset have the same effect on wheel bearings? For example, my rear wheels have 50mm offset, but I need to run 15mm spacers to clear the shock tower. So wouldn't that be the same as running a wheel w/ a 65mm offset? But no one ever mentions running high offset wheels can affect wheel bearings. Is there something I'm missing?
