I'm using the middle holes in the RPM arms. I was using the taller holes (closest to center), but I think that's what was causing my shock breakage.

For me, even silver is a bit on the soft side, which is stiffer than tan. I think I'll throw the silver back on but leave the oil light. I know it will be a bit bouncy, but I can't stand driving it as it is now. Maybe I'll replace about 25% of the oil with 55. It's either that or 90... that's all I have on hand.
