Thanks to both. Both useful sites. But both raise more queries.
Next day brakes show rear discs at different prices and I have seen this a lot but not understood why. And Buy Parts By show these discs at Half the price which leads me to suspect there is something wrong, even if it does say they are Brembo/TRW.
Any opinion on what pads to use? I would have thought Brembo would be good and the price seems ok. But Alfaholics say standard Brembo's can be made a lot better by fitting Ferodo DS2500 pads at a massive £190 a set. This is for standard road and occasionally spirited use and I am not the last of the late brakers!
Your inputs and experience here as ever are all welcome. Thanks.
I think BuyPartsBy are OK, a disc is pretty well a disc, I don't think the quality of steel comes into it particularly? Not as much as pad material, certainly. Beware though, when you see 'Brembo' or 'TRW' written, this means the part is to match
that OE manufacturer part which was fitted in the factory - it doesn't necessarily mean that it is
Brembo or TRW. If it actually says
the part is Brembo or TRW, then take that at face value (unless they're lying!)
If you buy genuine Brembo pads (all the NextDay stuff seems to be actually genuinely manufactured by Brembo) then they're gonna be pretty good. I have used the Ferodo DS2500 pads and they're very good, although they squeal a bit. I don't think you'll be able to buy them for a road car now though, I don't think they're homologated (officially tested for road use) any more. But the DSPerformance pads are pretty well the same pad and are legal in a road car.
Finally, the 'two different prices for the same discs' thing at NextDay brakes is down to the fact that the more expensive ones are painted with anti-rust paint. Yes, I know it doesn't say this but I emailed them to ask and that's what it is - I'm thinking of doing my own brakes pretty soon.
