Cheers for the review JS; gives a few different options to consider when i'm next changing. Yep, they are definitely DS2500s; i fitted them myself in June last year and have done around 8000miles since. I've recently had the car in the Isle of Man; and the de-restricted mountain road can be quite punishing on brakes; and a number of my miles have been towing my kart about on an unbraked trailer which I assume works the brakes harder than usual. I'll keep an eye on them, but i can't see them lasting over 15k. (maybe wearing out as fast as tyres was an exaggeration!)
this is running them on crn disks yes? cheese graters with all those wide grooves.. and you are surprised the pads are wearing faster?
tarox g88's do the same to pads, as well as crack from the root of the machined slots.
thats why i like both the ultimax and my own eliptical grooves, as function is still there but not at the expense of pad life compared to a lot of others
