T350 rear brake pad choice

[non_linear]

Time to replace the rear pads. I'm currently using the factory fitted Ferodo 3432F which I believe are no longer available.

I'm struggling to choose between DS Performance and DS2500. Ferodo claim the DS Performance has a higher friction coefficient than the DS2500 (0.46 average vs 0.42), so would appear to be a better pad for road use.

My planned usage is mainly road with a few light track days. How would DS Performace fare on a track?

Thanks

Thanks for your comments.

DS2500 seem to get a good write up, much less written about DS Performance. I'll bite the bullet and put DS2500 on the rear.
Point taken about brake balance. It will be my first track event so will be taking it easy, the fronts will probably need changing after that anyway so can match up the pads.
