At that time I chose a 19mm Subie RSB and the Perrin Rear end links. I have since gone to a Whiteline 22mm Adj RSB, still on the Perrin links.
*Note- I never found aftermarket end links specific to the Forester (110mm length). The WRX ones everyone gets are 95mm long. Will this affect performance? How much? I had lowered my XT by 25mm so the shorter 95's are actually a little long for my application (85mm would have kept the same geometry), but it has worked fine for me.
Ah, research time for me. Thanks for the info.
