Most positive caster possible on factory FB strut?
How much positive caster can I get by rotating the upper strut mount? Anyone shim these with a washer or 2?
Looking to get as much positive caster as I can with the OEM strut and no caster/camber plates.

-Thanks!

turn it and find out! you can also shorten the tension rods a little, and that will add caster, don't go nuts with this though, as the control arm will hit the subframe

remove what? the strut top? the strut is visibly off center, so you just rotate the block so the actual strut is inside and rearwards, and that is the maximum you get.

Avoiding rotating the top mount, then reinstalling to check the caster. I'd have to do this 3 times to figure out which gives me the most positive caster. I have the strut apart now with a digital angle meter and it's still really hard to tell which gives the most positive. Someone that has done this would know which position the top arrow points that results in the most positive caster. Thats what I was looking for.
