Also if I tighten or loosen the belts, do I also need to change the dog bones' geometry (which I suppose you are referring to the camber turnbuckle's height) by adding shims to make the camber turnbuckle's height to look more horizontally straight or slant? The key thing is I need more grip on my TRF419x's front and rear.
The TRF419x setup manual only mention about loosening and tightening the belt by changing the "k" indicator's position.
Please advise and thank you.
Tightening or loosening the belt is only, IMO, for freeing or tightening up the drive train. Belt stretch over time you adjust the tension according to the amount of sag you have on the belt. Tightening the belt also might also improve the initial responds, giving it a more "direct" feel feel as the belt doesnt need to take up the slackbefore the energy is transferred to the wheels, but this also means the motor is working harder because the drive train is not as smooth due to the tight belts.
Now for the position of the diff, either in the high or low position, have to do with the cars center of gravity. Lowering the spools moves the CG lower which would improve handling. But how much does moving the diff spool a few mm affect handling? I guess you would have to try it to find out.
