Review on 56Mm Black Wheel Center Caps by Kenneth Barnes

This is a very thick ABS plastic. Made in Germany. Well done but may need some tweaking/refining. Used on Subaru Outback Gen5 2015-2018 OEM 18" alloy wheels. A few notes: 1) The high dome of these center caps may not be suitable for flat or slightly curved decals. 2) Also inner diameter "ID" (clamp side) tight for Subaru OEM Alloy Wheels 51mm ID Out of the eight retaining tabs we had to break off the four smaller retaining tab clips (with pliers) and (with a high speed Dremel tool) grind the retaining slot in the remaining four large smooth clips to fully seat the center caps and to get to stay within the wheel centres.
