Hi all,
Couple of observations in some other threads got me thinking about proper orientation of the subframe bushings. I got AKG’s subframe bushings, which has two parts and metal sleeve., however thickness of the lip or shoulder of the two parts is different. So the orientation question: Does thicker or the thinner shoulder goes up towards the car body?
here is the pic of the bushing

Thanks Sean - that’s good news (no need to change anything) ! I was trying to get a hold of them via phone, but had no luck…

I had started to press one in and realized the shoulder thickness was different and no longer had the old ones to compare with. I am glad I noticed before they were in.
Saavy racers will soon figure out they can orient them the other way and raise the subframe in the car. I personally don’t think this is worth the effort in this class though.
Some guys do that with our powerflex bushings.

True, but that could potentially change the angle between driveshaft and diff (since diff is mounted on the subframe) and put additional stress on u-joints. Or would be change be so small that it wouldn’t matter?

One the powerflex bushings there is a pretty big difference in thickness between the two ends. I assume this is the same with the AKG bushings.
I’ve been thinking about Rob’s idea. What would be the effect of inverting the bushings? Obviously this would lower the CG of the rear 3/4 an inch or so, but would this have any effect on the alignment settings? I’ve been pondering this, but can’t convince myself as to what (if any) effect this would have.
Also, I’m not sure I’m understanding what difference the rotational orientation of the bushing has to do with anything? Anyone have a simple explanation?
