Great question. Looking at my order history in Amazon, they show as 5mm, but clicking on the link in the order story, takes me to a page showing 3mm. The packaging does not show a thickness. UPC of x001LYP415, FBA: V11519-PE, IPN:V11519Just curious, you mention 5mm spacers, but your link is for 3mm spacers. And the ones in your photos look like 3mm. Which did you end up using?? Thanks again for the great pics!
They are still on the car so I can't measure them to see what I ended up getting.
I can report that I've made several long trips, and had them to the drag strip for about 30 runs. Interesting thing is that it didn't make a notable improvement on my times in the 1/8th mile. I'm not sure if it's that the rubber is slipping more on the 18's to steal any improvement, or if it's just such a negligible change in weight placement that you don't see the difference. So do it for the ability to buy cheaper snows/rubber, not for the performance gains.
