They're the Movit Ceramics and they are utterly foible-free in every respect. Cold braking is just fine and very smooth - no grinding. When they get hot they just get stronger and stronger. The cornering shots were from a track day in May at RAF Odiham (The Chinook base near Basingstoke) and the main runway was the long straight. Was braking from 160 to 40 for the chicane lap after lap after lap. And all the while having plenty of other 100mph -to- 50mph corners in the back loop too. Utterly amazing.
Fine in the wet and cold (had them fitten in Nov-2008), so fully proven all round. Each assembled Disk/Bell weight 6.5kg. The OEM RS6 disks/bells weigh nearer to 12Kg. and the Calipers are much lighter too. Has reduced the pothole shimmy though the pedal-box significantly.
Movit ceramics are the long-chain type, so just look like very shiny graphite. Not the same as the road car discs from Porsche, Ferrari, Lambo or even Audi - they're the chopped and reconstituted carbon fibre types that are cheaper/quicker to make, but do grumble about quite a bit and as I understand it, don;t like freezing temps as much. Apparantly the Movits take 12 days to manufacture each disc..... far too long for series production cars.
Expensive, but utterly worth it. and I can move them onto the next vehicle too, assuming the wheels are big enough to accommodate a 400mm disc of course!
They are potentially fragile mind, so I have to make sure that Tyre and service dudes know not to drop the wheel onto the discs as they risk shattering them if given a big enough bang - that would be an expensive mistake. Think that's the only downside.
Main driver for me was that I trashed a new set of discs/pads all round in 9000 miles last year (2 Ring trips and a Bedford Autodrome day included) and that cost £1600. Repeat that a few times and you'll soon know about it. Movit ceramic discs are effectively guaranteed for life (150,000-200,000 miles) and a set of pads cost £134 I'm told. Cool!
