FSA BB30 With Lateral Play

Some BB30's have lateral play and this is taken up by the wavy washer. The washer takes up play from 1.5 to 2.2 mm. But some bikes have more side to side movement. 
FSA recommend 0.5mm plastic shims (Spacer kit of 3: MS 188) between bearing cover and wavy washer to remove exes play.

FSA Spacer kit ref: 230-4038:
0.5mm plastic shims fitted between bearing cover and wavy washer to remove exes play.

DESCRIPTION & MATERIALS: There are instances where despite proper installation of BB30 cranksets into BB30 or PF30 bottom bracket shells, there is “side play.” MS188 shims will remove the side play. Place the necessary shims between the non-drive bearing cover and wave spring washer (road) adjustment collar (for ATB).

Do not face or ream bottom bracket shell! This can possibly prevent proper installation of the crank. 

Specialized have come up with using adjustable conical spacers,to take up the lateral play.
