Festus, how did you get so much caster from slotting without giving up camber? I've slotted straight in for max negative camber and ground down the top mounting plate on the strut to get max neg camber (which is not quite enough judging from wear pattern on the RA-1's) but if I were to have slotted diagonally back, the inside radius of the strut tower would force less camber.
p.s. I join BC in experessing withdrawal symptoms. I instructed at a BMW school this weekend and took a ride in my friend's new D-Mod E30 M3 club racer and, man, there's no way I can wait til May for the racecar rush again! This might be the winter to do a race school somewhere warm.
