I purchased a set of four rotors last year for my '89 260e, but the rear rotors didn't include a hole for the rear hub's alignment pin (almost directly opposite the retainer hex screw). The parts supplier suggested that I simply cut-off the hub's alignment pin. But I was never quite comfortable doing so and only replace my rear brake pads. The pads need replacing again so my questions are as follows:

1) Is it okay to grind-off the alignment pin on the hub, or should I purchase a new set of rotors with the correct hole pattern?

2) If the consensus is to purchase a new set of rear rotors, then what brand model is recommended (as many of the rear rotor pics seem to show hole patterns that don't include a hole for the alignment pin).

Thanks in advance for your help.
