Adaptors designed to allow cars with single centre locking wheel nuts to be used with the applicable B-G Racing Hub Stand kit.
The collars are CNC machined in the UK from 6061 T6 aluminium and they are tailor made to match each wheel nut to ensure the Hub Stand centralises to provide repeatable measurements.
The kit generally consists of four to eight collars depending upon vehicle specific details.
