I was look at the post and everyone going crazy on the the camber links. longer shorter high lower!! this is how i do it// i tune rear of the truck for on power only
and we are on power a good 80% of the time so i only going to do the rear link.

I like to get the ball stud as close as is can to the middle of the truck on the shock tower( it dose give you more steering entering the corner but i tune the front for that) to give me more traction on exit by letting the truck get more weight on the out side tire. (if your on a vary hi traction track put ball stud on outer hole if you need the more on power steering)
after i do that i try to get the ball stud a low as i need it. on this truck the trick is to shave the brace #9564 even where the ball studs goes it like 2mm to make even. what this dose is give the truck more camber gain. what that dose is let you run your tires more up right for more forward grip(in stright line) and not let it flip or grab ruts as bad.
both of these trick together help you get the most corner grip,forward grip and not flip.

but still the hub dose funny things
if you mount on the out side hole on hub you get the stability going into the corner like you would think but you dont get the grip on exit /it tend to drift or steer a little more less roll. the inside hole on hub give you less exit steering with more roll or grip. so what i do is if i want more steering the more out i go on the hub. if to much steering go in on hub. (remember most of you driving is on power so go by on power first)
last on the hub higher ball stud gain camber gain lower decrease camber gain.(if you shave the part number #9564 like i did on top) if you put you ball stud higher it be good for 1/8 track that are rutted up from the bigger buggies.

if you notice longer link/short link dose not work like you think so everyone wrong and right at the same time. it where you put the ball studs not really the link it self. so if ball stud is on inside shock tower and inside hub your on very very low grip track. out side tower out side hub very very high grip track. but yes a longer link over all will be more stable and more grip. shorter link overall less rear grip but more steering.

one last thing this is only for the rear 80% of your tune. if you try this on the front you be off 20%!!!! this is the way i tune!!! it could be wrong?? if so plz tell me!!! i dont have 20years of experience in this like i see everyone else say(i would had to start at 7)!!! but it should help everyone new or used tune a little better!!!
