I tried posting this yesterday but it ended up in the archived files because I was adding it to an old thread. It generated one response-- thanks, ThreeBsRacing-- but I'm trying it here too in case there's more to be said about it. Thanks!
So I'm installing Whiteline bushings in my moustache bar. The diameter is perfect-- the earlier posts in this thread alerted me to the differences so that I ordered the right set. No problem there.
The issue is that the heights of the two halves of each bushings-- top and bottom-- are different. The "shoulder" that sticks up (or down) beyond the moustache bar projects up (or down) by 8 mm on two of the halves, and 14 mm on the other two. So the steel tube that goes through the centre of the bushings (which also fits nicely snug, no problem) projects a different amount on each side of the bar: also 8 mm in one direction and 14mm in the other. See photo below.
The issue is, should the bigger dimension be above or below the moustache bar? With the stock set-up, the distances are quite close to being equal: 10 mm above, and 12mm below. See photo below.
In a sense this hardly seems to matter. But enough has been said in this thread about driveline alignment to make me wonder. If the new set of bushings gives me either 8 or 14 mm between the moustache bar and the frame, depending which half of the pair is facing up, and the original set gave me 10 mm in that same dimension-- well, what about this? Is there a problem here, or not? I don't want to be hyper about it... but nor do I want to blithely assume it makes no difference.
Analyses? Suggestions?
