I bought these for less than $80 shipped, total, for all 4. Fronts and rears. 20mm and 25mm respectively. They aren't too heavy, and are hubcentric inside and out, so your hub fits perfectly inside, and wheels fit perfectly outside.

I wasn't expecting much, honestly, as they were about the half the price as everyone else seems to by paying for spacers. I now have a little over 100 miles on them, and they are perfect! No rattling, rubbing, chattering, clanking, nothing. They have a perfect fit. The studs were high quality, and they come with all the mounting nuts.

I would definitely recommend.

The seller shipped them almost immediately, and made it to me in a couple days. Here is the link to the seller I went with, even though there are multiple sellers:

I've found that 90% of wheel spacers are basically the same no matter the seller. Most differences are finish of the metal (polished, dull, anodized). Be sure to inspect them and torque properly and you shouldn't have issues.

 

I have these are well on my 08 Sedan but 15MM all around and i agree they are perfect. The car looks perfect with them and the drop and it is Smooth as it was before. No vibrations or anything. Awesome product.

 

Good to hear, I never understood why a couple of CNC'd or milled pieces of metal were so damn expensive. Once the dimensions are perfected they just spit out thousands of these things and make a killing. Their cost is like $5 a piece, if that.. Ridiculous.
