Hi, recent 08 Vantage roadster owner. Getting to know the car and loving it. I noticed today that the machined grooves on the outer face of the brake rotors (and probably the ones on the inner face also, but no visible) are oriented differently on the RHS than on the LHS, as if the rotors are not "handed". When stationary, the groove closer to the hub of the rotor on the LHS rotor is say at the 3 o'clock position and the groove goes counter clockwise as it eminates towards the outer edge of the rotor (or clockwise, I cannot recall exact details). While on the RHS rotor it goes clockwise (the grooves are not radial) It is as if the LHS rotor and the RHS rotor are the same part # and are not "handed". Is this normal or has previous owner had 2 off LHS rotors fitted (or 2 RHS rotors as the case may be)?

 

The OEM rotors are all unidirectional, so the slots will face forward on one side and rearward on the other side.

 

Thanks Telum01, so the previous owner did not goof up, if the rotors have been replaced.
Great informative YouTube videos, by the way. Again thanks.

 

No problem!

And thanks for the feedback on the videos! I'm actually trying to finish up the brake/clutch fluid flush video right now and I just lost the entire thing sooooo I have to start over. I'll try to get it posted tomorrow...
