Guys,
Ran one of Jamie's prototype links on my 502 today at Maritime. I used in the "forward" position as per Jamie's pics above. Goes on easily, reduces the slop compared to the standard part and as Jamie says is just the right shape to mean on full lock you just clear the gearbox case!
This definitely helps the lock on the outer wheel, plenty of hairpins and tight corners at Maritime today and for the first time since I've run the 502 I had plenty of steering on those tighter turns, helps me recover the line when my turn in isn't so precise as well!
Overall, it's well made even as the proto, and I'll definitely be buying one of the production ones as soon as they are available, it's a valuable tuning aid as far as I'm concerned!
Cheers for lending me the part Jamie
