Im running the super lightweight shockproof, have been for the last couple of years with no dramas at all, shifts smooth as. I when i first changed the oil i put something a bit thicker in (cant remember specifically what it was) but it made it hard to change and sticky, since the shockproof its faultless. Im running redline stuff in the diff too.
Glad someone is happy with it too.
Hey don't get me wrong, the stuff is remarkably good. I mean my gearbox had a completely shagged input bearing, and pretty servere 1st gear damage due to what looks like a lack of lubrication. With a normal gear oil in it, It was just about unshiftable. ~3.5lts of light weight shockproof later and it was shifting better than a brand new Tremec...
