start by stiffening up the chassis as much as possible. sub frame connectors, export brace, and monte carlo bar. then add some stringers from the sub frame connectors to the inner rocker panel to tie everything together.
next upgrade to a 540lb rate front spring and a 200lb rate rear spring. while you are upgrading the springs, do the shelby mod.
then upgrade your shocks, the kyb gr2s are good ones for ride and handling.
after that upgrade the lower control arm to a boxed unit with a spherical bearing, and add roller spring perches, as well as adjustable strut rods.
top this package off with 15x7 wheels wrapped in a 205/65-15 or a 225/60-15 tire and a 1" front sway bar. if oyu have a V8 car add a 3/4" rear bar.
my mind is aglow with whirling transient nodes of thought careening through a cosmic vapor of invention.
