hi Jon,
i had a s120 for a while, and with 2xpink front/rear, the stock setup had an onpower push for me as well. (at Beltran's, concrete sprayed with sugar and/or vht)
for me i needed to stiffen the tbar to better rotation. the s120 is peculiar in that you can stiffen the tbar (other cars you swap tbars) by moving the restraint, but be careful to just change the length of the bending beam (shorter is stiffer) but don't move the point where they contact the tbar.
i tried moving the contact along the tbar and it made weird things happen, it couples up tbar bending and torsion, so if the tbar bends, the roll stiffness increases, making more unsettled over a bump in a corner.
for me, it worked best when the contact to the tbar was at the fwd pivot.
i never tried putting contact at the aft pivot, but that might work too if you really want to stiffen it up a lot. but i doubt that will be necessary.
