Does anybody have a G37 coupe on stock rims with spacers? I have been considering purchasing 20mm spacers all around but have yet to make a decision.I’ve been wondering what it would look like after the upgrade. If I decided to get spacers, would I need some type of lowering kit? Any input is appreciated! Thanks!​​​​​​

Here is my stock G coupe on 18” OEM’s

 

Spacers do not require lowering. It just pushes the wheel further out. Check Z1 Motorsports for options.

 

Spacers are a step forward to better fitment with stock wheels. Jpowers couldn’t have said it any better! All spacers do is bring out the wheel

 

To add to what the others said, if you haven't done it, I'd measure out and make sure 20mm is what you need. You can kind of eyeball it from the top of the tire out to the edge of the fender and get a good idea, but I have spacers on my stock IPL wheels. It definitely helps the look, lowered or not!
