I sold my 93 z28 6 speed and will be looking for Ls1 T/A hopefully soon.
I drove my buddies 95 Supra all the way from Va to FL and if my Camaro handled as well as the Supra, I would have never sold it. I want to know can I get this handling from a late model T/A ?

Absolutely. Springs, shocks, & swaybars are the best starters. Just look around and you'll find a ton of info on what's best. I think as far as shocks are concerned the best are either konis or revalved bilsteins. Springs are more a matter of ride height and stiffness, you don't have to be as worried about individual brands on that.

Our cars are always going to be a bit squirrely on bumps compared to IRS cars... but some money spent in suspension upgrades will improve the handling of the car a lot. The supra is also a bit of a pig so the two would probably compare reasonably well when your LS1 is set up properly.

Really think springs aren't better by brand name?

I would be more concerned about spring rate and ride height than I would about which brand they are. BTW I'm not saying that cut springs, ebay springs, etc. are the way to go. Eibach, BMR, as long as it HAS a brand name it should be good. Of course, there are springs that are more suitable for a specific for a specific purpose than others; for instance, I've got variable rate springs on the back of my car- great for going over railroad tracks, but probably less predictable on the track.

sway bars made my car feel like a totally new vehicle...

as did the SFC...much more solid in the uneven pavement and in curves. made me realize how bad the crappy stock shocks actually were.

still waiting to upgrade
