I can personally vouch for the quality of these shocks. You can even ask @
Alin and @
WRB_STi, they've ridden in the Batmobile.
I have Race Comp Engineering "Yellows" springs (-25mm front, -20mm rear. "Street and Track") dampened by the Tokico's. End links,
sway bars and mounts, urethane bushings and a roll center adjust kit. Depending on what you want out of the handling, I might not
necessarily suggest these springs, though I am pleased with them. Building a well rounded, balanced suspension is much more than
just installing stiff springs or coilovers. It will handle fairly well but also ride very harshly on public roads for example.
