Schumacher Icon thread insert kit

From Schumacher, this Icon thread insert kit includes everything needed to replace the M4 nuts on the front wing assembly with easier to use M4 thread inserts. This greatly improves the security, ease of fitting and removal of the front wing and enables the wing to be fitted with both screws when also using the U8123 narrow width option.
