BMW M4 GT4 Style GRP Doors

BMW M4 GT4 Style Doors - Fibreglass GRP
 
BMW M4 GT4 style doors. 
 
 These doors have been developed with weight saving in mind, reducing the weight of a single door from the OEM spec of 30KG to 8KG.
 
Unlike many other FRP options though these retain hinges and handles, as well as inner and outer door trim. Needless to say the weight-saving of a potential 44KG is massive, and makes all the difference.
