the frs paddle i used wasn't so bad to be honest, just needed a few more revs when slipping in traffic. light pedal due to hydraulics too. they do an organic plate rated to the same though. it took all the abuse i sent it's way and no issues, i dare say it would have taken a lot more, but i would have only been just over 400bhp i suspect though.
sach's stuff is well rated too, i wouldn't discount it.
