I have a pair of 20mm and a pair of 25mm 5x100 to 5x112 adapters. I went through a fellow Vortex member years ago and had them made, so there is no brand or anything on them. Adapters have a centerbore of 57.1 I used them for about 3 or 4 years to put Mercedes 8-Holes on my MK3 Jetta and never had any issues with them.
The Negative: I let a friend borrow them, so one stud is shorter than the others and said friend lost 2 lug bolts.
Price is $150 shipped or best offer.
