M5 Rear Sway Bar Dimensions?
A reach out for info.
A bunch of us F10 NON M5 owners are contemplating sway bar upgrades. We already know the M5 front bar fits and now have to pick a rear bar. It appears that the F07 (GT) rear bar (for non ARS cars) will fit but comes in two sizes, 16 and 18mm.
Wanting to match the M5 front bar as the factory did, can any of you M5ers let us know the diameter of your rear bar? (It should be indicated on the barcode label stuck onto the bar itself).
