I must admit the quality of these adapters was very nice… BUT!The 1 inch adapters that we purchased, for our 2014 Chevy Cruze, came as 5×112 bolt pattern with M14x1.5 lugs.The car actually has a, 5×105 bolt pattern with M12x1.5 lugs and a 70mm bore.I will be returning these…

Had to use these hub step down / stud conversion wheel spacers to fit VW GTI fitment wheels on my ML55 with off-road tires. The cars share bolt patterns but the hub size is too small on the wheel. I have taken them out off-roading with semi aggressive crawling involved 3 times this last year and have taken wheels off multiple times and changed tire sizes. I check torque often though they never loosen. I beat on this car with this setup and it holds up so overall I’m impressed for price. The hub centric fitment is right on and they work.

Exactly what i was looking for. thank you

The fitment is perfect and these feel and look very well made. I bought them to install wheels from a Bentley onto a BMW X7.
