i see that when you order a set they include a decal sheet to be placed on the rims. my question is are the decals durable? how long do they last under regular driving conditions and how do you go about cleaning them?

 

They're vinyl stickers, and they'll last a good while as long as you install them on a clean surface and take care of them. I've got vinyl stickers on my R/C Starks, and I beat the crap out of them. They're doing fine, almost a year later.
