I'm a bit bored so I'm thinking about putting wheel spacers on my Roomy.

What do you think? Is it worth it? Is it safe?

I was thinking about 16mm up to 20mm spacers only on rear wheels, or even all four wheels. I don't want shorter or longer spacers for safety reasons.

Roomy has familiar 5x100 bolt pattern so finding good quality spacers shouldn't be a problem, right?

Thanks four your advice

Eibach 15mm hubcentrics are the best I think. Just need longer wheel bolts though. For 20mm I think you usually bolt the spacer to the hub, then the wheels bolt to the spacer using normal bolts.

Right, I'd like the wheels to hang on the spacers not the bolts. That would do. This is why I'm thinking 16-20mm would be the best option.
