Anyone using wheel spacers here?

Moderators, pardon me if I have posted in wrong folder. Was wondering whether this should go Aftermarket or Rubber/Wheels folder.

 

I've searched for spacers, and its a taboo topic in the past. But with well-known manufacturers like Eibach having a wide pro-spacer product series, I would think that the technology has improved.

 

Anyone who have been using spacers for a while, those bolt-on type, any comments or feedback? My application is for aestetics purpose, though it can improve handling marginally.
