I saw that Primera knob and it looked good but couldn't find any for sale and wanted something new.
I have seen these knobs and the Skunk 2 is nice but the thing stopping me from buying it is the but at the bottom which wouldn't sit right with the finisher. Been looking at loads in america but the cheapest one I found which was nice was £60+ and I wasn't that in love with it.
The blox one is to OTT for me with the colours, needs to be a brushed silver really.
But I do like the shape of those, I'm not a massive fan of the thin Nismo ones.
