    Hi guys,

    Just wondering who here is using these? and for how long?

    I'm a bit worried that removing material from inside the rotors will weaken them, god knows how fast these things spin with a 2.55" pulley, and the enourmous kinetic and centrifugal force exerted on the rotors... this might cause them to eventually warp and shatter and send pieces of rotor into my engine?

    Anyway, would be good to hear of people who have used these for a good while.

    Cheers

    I have been running them for some time now, about 2 years. They were running with a over drive balancer and a 61mm blower pulley for a couple of years, now I am running a 56mm blower pulley with the over drive balancer. Rotors are still intact, even the coating is putting up with the punishment!

    Hi Schwuppes,

    Thank you for your enquiry:

    "Just wondering who here is using these? and for how long?

    This is not an uncommon concern you have. While I can't speak on behalf of others, we've officially had this product on the market for over 4 years, with development of this project having commenced around 6 years ago. As such we've never has any issues with the rotors themselves failing, which is reflected by the fact that they come with a lifetime warranty with the exception of the bearings and seals used in them.

    If you have any questions please don't hesitate to ask

    Kindest Regards,
    Steve

    Rotors will not fail. I've seen install mistakes cause massive damage, same as could happen on stock rotors. These rotors make a difference to the initial throttle hit and carry on through the rev range

    install mistakes? I wouldnt have thought theres much to it... slide in the new rotors... obviously make sure they go into the needle bearings at the back properly... then put the bolts back on lol

    What your saying largely sums the overall installation process, however any foreign matter could complicate (read damage) the rotor installation process.

    So, Mace and Steve, seems these days you're out of stock of the lightened rotors. Is it possible to send mine down to you for machining and have them sent back up after?

    We are not out of stock as such, more so the resources to be able to do them again these days :( But is a great product nonetheless
