I ordered a used "good" and risked it. They look like new and unused. They came in a plain box with no KSP stamp on the box, contrary to what was described in the ad. I was concerned that these might not be genuine KSP products so I contacted KSP and they assured me they were KSP spacers. The ad says 12.9 rivets and they have 10.9 rivets. I was concerned but after doing some research they should be stronger than the OEM grade 8.8. I wire brushed the hubs and painted them with Rust-Oleum. I used the blue latch on the factory studs only to secure the spacers and applied anti-seize compound to the spacer wheel studs in case they rusted. I checked the spacers and then the spacer wheel, all to 150lb Ford spec and so far so good, no breakage. I'll pull everything up after 50 miles and update if I run into any issues.
