Steel Rotors for V12V

[RiknRoll]

Anyone ever fitted Steel Rotors and corresponding pads to their V12 Vantages for track use? I hear a lot of Porsche and other folk do so. Would mean could buy a set, use them over several track days and save the carbon ceramics (which by the sounds o fit don't last a huge amount of time on track).

That's kinda like fitting drum brakes to an E30 M3???

Not at all actually, the various porsche/bmw etc owners who regularly do this use the same calipers. Theoretically there shouldn't be any major difference in stopping power at all by using steel rotors, you just have to be aware they are susceptible to brake fade and overheating, especially on heavier cars. But the cost difference is usually vast, which is why regular track users do it. From a couple of chats with Aston dealers and viewing of forums, it's quite possible to go through a set of Carbon Ceramics in 3-4 good track days... at a cost of £6500+VAT (excluding fitting) per set.

My only question is that has anyone done it with an Aston, and is there any reason it can't or shouldn't be done?

I think someone asked in the now deleted Bamford Rose thread. It could be worth giving them a call.

I've been trying all week! not had a pickup even once (from about a dozen attempts)

You can burn out a set of carbon ceramic disks in one track day. Just overheat them and keep them hot...

You can fit iron disks, but you need different venting, venting air to the disk not the caliper.

And £6k is cheap, too cheap for four new disks.

seems you are right I'm speaking to another dealer and hes reckoning around £17k for a full set!

I'm finding more steel conversions being offered...

I suspect that's per axle set. £6500 + vat = £7800. Fitting? (most dealers now seem to charge in excess of £25 per hour ). Pads included?

That soon starts to become 'slightly expensive' in most people's books for a wear and tear part.

Alternative = 1350€ per front refurfished CCM disc and 1255 for rear

I was led to believe that a fully fitted set all around was about £10-11k, not sure where the £17k comes from.

So for something like a 991 where CCB's were a factory upgrade, then obviously with steel being standard there's clearly a complete swap over kit available off of the shelf. As that's not the case with the V12V then whilst I'm sure it could be done (like anything can), i'd doubt it's a simple as throwing on the brakes from a V8S........although I could be talking ste

I'd speak to Alcon http://www.alcon.co.uk they did the brakes on the new GT3 and I'm sure they could come up something suitable for the V12

I’m sure the steel discs on the DB11 and new Vantage are same diameter and thickness as the V12V carbons. I’m unsure if the PCD and CB are the same on the latest cars, but if they are then it’s only the offset of the bell which would need to be conquered to make them fit. Would be too good to be true if every dimension matched but has anyone looked into it in any detail?

You never know...

£17k was from my conversation with Aston Martin Wellyn.

And indeed it's not as simple as throwing on V8S discs, different size, I'm told.

Thanks to the other posters, also, for the various suggestions. I'm also doing some work in the background so hope to have a clearer picture in th enext few days, most likely next week. I'll post up any results I get here.

think this is to refurbish your own discs - not a terrible option, at least way better than a new set, but no idea how well it actually works.... or whether it's possible to tell and therefore off-putting to potentially buyers.
