Cannot get full front suspension rebound.

As a comment on the bumpstops, with the very heavy T-bars that the OP is using, I am seriously doubting that the full droop will every be used...and if it is, the T-bars will be beyond fully 'unwinding'. I've been doing some prelim calcs on a rally suspension and have run into this issue with the heavy T-bars.

And glad to see that the heim's on the street issue is getting some attention. Shock and impact wear on everything goes way up whenever you get rid of the rubber.

So OP, you have maybe a 2ND bad arm? That is pretty amazing....
