Default Outer Rotor Diameter

I noticed two different sized rotors being listed for 93-940...the designs are different, but will they interchange?


Outer (IN) 11.295

Outer (in) 11

No, measure the rotors you have on now, and order the same size if you're keeping everything else stock.

93 940 should be 280mm (11 in.). 287mm (11.3 in) was last used on 1991 740 w/o ABS. The 2 rotors are not the same thickness.

In those years, on 740s/940s, Volvo used rotors with

Outboard Vented Vents On Wheel Side Of Rotor

and rotors with

Inboard Vented Vents On Axle Side Of Rotor

For the 1993-940 I own, it takes the smaller diameter rotor (11") with inboard venting on axle side. The outboard vented rotor is about 11.3" in diameter.

0.3" would give a pinch more braking, but I know nothing about why Volvo flipped around.

The "smaller" 11" rotor with inside air intake is also thicker and considered the HD version.
