Longer ball studs
 

Is it Losi that do a longer ball stud for the inner rear camber link to allow the ball to be lowered a bit more, does anyone have a part number if so?

not got part number but yeah losi do longer ones. Got some on back of mine. Using those low profile nuts (1/4" socket!!) that are on the top shock mounts as well on the back. Nylon grips sooner than the small blue ones.
