Hi All, hoping to pick pick your brain.  Bought some brembo 4 pot rears brand new off EBay, part number 20.A378.21,  they have the same part number as others for sale on there and said they were to suit an FG FPV etc, went to put them on my G6E with some DBA rotors (DBA42108S) and the back of the rotor is binding slightly on the caliper when the calliper is tightened up.   I’ve previously fitted up brembo 6 pots to the front without any issues.  I have aftermarket wheels with enough clearance for brembos.  Wouldn’t have thought the hub setup etc wouldn’t be any different between my car and an FPV or am I wrong?  I’ll talk to Racebrakes tomorrow about the rotors to see if they have any different offsets. Would welcome any other thoughts.

DBA42108S is a 328mm rotor (Early BF / Territory rear), I believe the Brembo rears are 330mm.

 

I have heard of people making that disc work with spacers but that's not something I would try.

 

You may just have the wrong discs
