Pagid RSL29 Availability or an Alternative Option
Discussion
I have recently fitted Girodiscs to my 991.2GTS. I am running them with OEM pads, which has created a problem. The pads are over heading and depositing themselves on the docs surface, which over time translates in to a 'drone' and bit of judder under braking. I need a higher performing brake pad and thought I'd go for the Pagid RSL 29's but availability is proving difficult at the moment (remembering that the callipers on the GTS are not the same as a GT3/4.
Does anybody know who might stock these pads or is there a similar performing alternative that can work with the Girodiscs and withstand the heat generated on track?

Pad transfer is entirely normal, and required.Does anybody know who might stock these pads or is there a similar performing alternative that can work with the Girodiscs and withstand the heat generated on track?
It sounds like you're describing uneven pad transfer - which is a real PITA. I've had varying degrees of success with running RS29's after other pads on the same discs. Attempting to replace the already deposited transfer layer has often led to the new pad deposits being uneven and patchy which leads to vibration not unlike warped discs.. The only way to "clean" the face of the discs is to potter around without getting too much heat into the pads such that they operate beneath the temperature at which transfer occurs, and they are instead more abrasive. Once this is done, you can then go through the bedding-in process again (which for Pagid's tends to be quite prescriptive) in the hope you get an even transfer layer.
In your case, I'm assuming you've only ever used the OE pads on those discs, so could it be that the bedding-in process was not followed, or non-existent?
I prefer to switch to RS29's only when replacing the discs at the same time these days, so that I'm starting with a blank canvass. I fear switching to RS29's when you already have an uneven transfer layer is not likely to solve your problem.

Speaking to Martin he seems to think that the current OEM pad material on my Girodiscs can probably be removed with some 80 grit wet and dry on an electric palm sander. My pads were used so had already heat clyde before I bedded them into the new Girodiscs so the amount of material that has been transferred is not excessive.
I did follow the exact bedding in process for Girodiscs and the OEM pads were fine on the road and ok for the first track day, but have got progressively worse on two subsequent track days.
Your suggestion of possibly using the new Pagid RSL29's to 'clean' the Girodiscs at a low operating temperature sounds like a good idea. I might try the wet and dry on the discs followed by low tap running to clean and then bedd in more aggressively.
