Different pad compounds on used rotors
Switching from Ferodo DS2500 to Pagid RSL 29 on my 718 Cayman S with Sebro slotted rotors. The Ferodos work fine for me but have a very short lifespan. Rotors still have a lot of life in them so I'd like to continue using them. I also know that it's better to have either used pads or rotors rather than have everything new at the same time.
I plan on using Pagid's standard bedding procedure or something similar from other threads I've found here on RL. Anything I should change in the bed in process or be aware of relative to the compound change?
Thanks.

I recommend driving the car with new pads for a few weeks on the street to try and remove some of the old pad materials since they will be more abrasive when cold.
Then I would just beat on them on track and have a set of backup rotors there just in case/worst case scenario. Never had much luck using some sort of magical be-in proceedure so I toss them in and go for broke.

We get this question everyday.
You should be fine, but make sure to bed the pads in before taking them to the track.
If your rotors are "dished" or grooved you might notice the new pad is not mating completely with the rotor, this is not ideal but we have had customer's that simply keep on driving the car and eventually the new pad "wears in" to the used rotor.
Shameless plug- we have new Girodisc rotors in stock

Follow up question - is it OK to put new pads and rotors together? For track use, I've heard it's best to mix old pads with new rotors or vice versa.
General consumer sites say the opposite (ie - new pads should always have new rotors).
Which is it?

If you want a longer lifespan out of Ferodo pads, you need to go with one of their endurance racing pads, which are the DS1.11 or DS3.12. The DS2500 are a different class of pad (light duty track/sport) and can’t be expected to provide the longevity of an endurance racing compound. One of the great things about sticking within the Ferodo DS range of compounds is that you can freely interchange them without having to worry about scraping the old Ferodo material off. They all play nice together on the disc face.
Here’s an article with more details on each Ferodo compound:
