Looks like a solid set, shame it doesn't come with a matching dead pedal cover, though.
Should help with the ball rolling method, and would allow you to keep your foot centered a bit more on the brake, possibly.
I've been considering these
Rennline pedals for a while now, since they have extensions at the top and bottom. When I'm street driving I use the ball rolling method 95% of the time, but at the track that method usually doesn't give me the ability to brake aggressively enough, so I end up reverting to an actual heel-toe.
