Cool thread, love the pics.
Interesting feedback on the OSG Super Lock. I wonder if you got a bad unit? We have sold many of these with nothing but excellent reviews. (circuit, rally and hill climb clients primarily) The most winning BMW team in American circuit racing runs OSG with no issues and we run them in our cars as well. Looking FW to seeing your next attempt with the SL.
Ironically, one of our dealers in Belgium was here in Philly yesterday and he told me he switched from Drexler to OSG in his rally cars (two S54 E87s, one 2.7 S15 E30M3 - all with Drenth sequentials) and it worked MUCH better for his needs.
