Thread: Slotted Disc Rotors?

    Slotted Disc Rotors?

    I got a bit of a shock the other day when I looked at the front discs & saw the size of the lip around the perimeter.

    In the past, with other vehicles, I have used RDA slotted rotors as replacements, are there any issues with using these or similar on the D2 TD5?

    Any other recommendations?

    No, I went away from the factory pads due to the dust. I use Bendix pads which have not cause 3 amigo problems.

    i tried bendix on the D1 for 2 sets of pads and 1 set on the 90 (td5) and i found they would squeel on very cold mornings first up and after water crossings/mud. ive only ever used lucas pads after for the 90 and now the D2, no issues except the dust as simon mentions but its a D2A HSE so it has to be kept clean weekly so its not an issue for me

    there also usefull as a break pad indicator, no dust=no pads
    cheers phil

    The main concern with slotted disc's is, sand or sloppy mud may get stuck in the slots and damage the pads/rotor. Never had them so I can't say if its true.

    cross drilled are the issue not slotted.
    the slots in the disc face are only 3mm max deep, no mud in there
    the cross drilled slotted and vented(all on the same disc) ones tend to lead to cracking, dont think ive ever heard of any fail though.

    Spot on Phil...

    Slotted are fantastic offroad, clearing grit and muck from the pads and preventing damage from trapped materials.

    slotted for your application simply means less surface area which technically means, less braking power. Slotted does play a big part in certain applications, however. I love the APracing slotted pattern.

    Cross drilled is not that bad at all. New Porsche GT2 RS still uses them, for example So do Lambo and Ferrari.
