Braking issues ...

[Roadrunner13]

I'm the second owner of my Roadster, the brakes were stock when I bought it. Original discs (rotors) and pads probably second set. I've replaced the pads with EBC Yellowstuff and left the discs for now, bled the system and replaced brake fluid. Roadster stops pretty good compared to other performance cars I've owned and driven (Caymans, RX-8s, TTs, M3s). Tyres and road conditions make a big difference, certainly without regen, I don't have any concerns about stopping. Discs due to be replaced in next few months, and will replace with EBC USRs slotted and drilled discs which will look better and improve overall braking. I've not seen the need to go for ceramic discs as others have...

They just ran a new group of 20 sets of Titanium disks for the roadsters and there are two sets left unclaimed!
