Hey, when you guys do the mains on the Z do you use two sets to make a 360 grooved bearing? Common Lotus 907 trick to help with oiling, do the Z guys do it too? I noticed I have a spare main bearing set in the spares that came with the car, but only half of them are grooved. Could buy another set and only use 1/2 for each set.

I have two comments on this procedure. First, aren't bearing halves supposed to be mated for life? I guess the procedure could be beneficial, but couldn't one also end up with a mis-matched pair of halves that might be more detrimental than beneficial?

Second, someone may correct me (and that's okay ), but I would consider this to be well into the grey area WRT the IT ruleset. Aren't you essentially creating replacement parts that don't meet OEM spec when you do this?
