OSIR was the first place I looked as the mk6 extensions were really nice and I think they fastened over the stock ones with a grub screw.
The paddles need to be tactile and sturdy for me, the only time I use them is when I'm giving it some so as I'm clicking through the gears I don't wanna be worrying about them falling off.
Yeah, they've got to be substantial which is why stick on ones are a no-no.
If OSIR do bring out Mk7 paddle shifters in coming weeks I hope they are sufficiently different to the Mk6 ones which are a bit too stubby.
Hoping also that the OSIR Mk7 goodies include a dead pedal footrest, as if their other ones are anything to go by, it should be a thing of beauty, but mega ££££ no doubt.
