I got a set of these in my 911 and have a set to be installed on the 914
Don't have any 'grip issues', unless I'm wearing my pimp/dancing shoes (which I try to avoid as much as possible
) and it's wet outside...
They bolt over the existing pedals
The brake and gas pedal are sleightly wider, which helps 'heel & toe' action
And at $15 a set, they're hard to beat (OMP, Sparco etc. all sell them)
cheers,
Jeroen
