on the rear hubs the only way to make the outside work is to shave the inside at and angle ( o i ) (o \ )
o = outside
i= inside
\= cut the inside hole area at an angle
and then the new short arms react different to changes then the old long arms.
IE on my t1r i ran super long fornt link and tried it on new fk and it sucked went to super short and it was bomb so stuff is almost switched around a little
just try stuff out and see what works for you.
