I have used vernier sprockets on my TR3, my wife's TR6 and my Bugeye race cars, and haven't had any issues. I don't torque them to a specific number since mine are all aluminum, but I do Loctite blue the screws. Have never had any slipping or wear issues. And the ability to get the cam timing just right is awfully nice, especially on the 3 as it's so critical. </div><div dir="ltr"><br clear="none"></div><div dir="ltr">Cheers,</div><div dir="ltr">Jake</div><div><br clear="none"></div>
