The Ferrodo DS2500 are brilliant...
... but the Pagids are certainly a very good pad too and far superior to the likes of EBC (yellow) etc.
Have used some of their track pads on customer cars in the late 90s and certainly top choice at the time.
Same with oem road pads for the likes of Audis and Porsche etc... very good and have run the oem road pads in my blob, and my hawk came with them fitted when I bought it (every bit as good or better than the Subaru oem).
Not familiar with the RSL29 though, but certainly their other pads are top quality stuff and I cannot imagine this one is any different.
