Yeah, I'm interested to know how you like it all as well. I'm looking at a '91 Firebird right now (not Formula/TA), and I have all of these mods planned as well, except I'd be going the cheap route in the way of shocks/struts...I'd be going with the KYB GR2/Gas-A-Just combo. I'll probably ditch the panhard bar and go with a STB and wonderbar though first. And I'm not sure if I'll go with the adjustable LCAs; I might just go non-adjustable. I'll be picking up a set of Spohn SFCs as well as some WS6/IROC swaybars and a full ES hyperflex/master kit. I also have my eyes on the Eibach Pro-Kit.
Should be a HUGE difference over a stock Firebird suspension with nearly 150k miles on it...which would itself even be a huge step above the '90 Plymouth Sundance I'm driving in now
Suspension this summer, other power-supporting mods this winter (new posi disc rear, alum driveshaft, torque arm maybe, etc.), and a built 355 next summer..and then maybe a blown 383 the summer after
