I've been running these for about a year and a half now (30k miles) with Ferrodo DS2500.
My thoughts on the setup are as follows:
Cold bite is a little better than OEM Once warmed up they are blindingly good for the price You need to bed them in properly unless they will squeal and performance wont quite be there Dust is no worse than OEM really, but also no better. Make sure your wheels are sealed with something like PB wheel sealant and it wont be a problem Also leave your car in gear and with the handbrake off when parked. I noticed that if I left the handbrake on, it could bind to the disc leaving pad material behind which leads to brake judder.
I fully recommend the setup. I might look to run the plain DS pads next as they are less track orientated and more road pads. Should mean cold bit is better but when warm they wont quite be on par with the DS2500.
The DS pads are great, amazing value too, I was speaking to Zedwagon, who was the first to get the pads off me and she really likes the pad, a big improvement over the standard pads...
Mike's discs are £221.00, however, for members I do them for £208.00 delivered...
