That depends on what you want to do with your car bud.
sorry for the vague response but truly, what you want your car to be, how you want to drive it, this is what you need to decide what to do next...Budget is important as well.
You have a LOT of f-body owners who would swear that the sportline springs are basically for looks ONLY...They're too soft, too low, any kind of spirited driving will cause your suspension to bottom out and your rear axle will be banging off of the bumpstops.
Most people tend to get rid of the sportlines and go to different springs like HR or BMR or even the Eibach Prokits(better than the sportlines for performance purposes) but for the greatest handling/bang for the buck option you'll hear Sam Strano springs and Koni SA shocks 4/4 all the way around.
GREAT handling, stiff, greatly reduces body roll, it'll make your car feel like a race machine TRUE STORY!!!
But see, that's if you want a GREAT handler.
If you want 1/4 superiority, then that's an entirely different suspension altogether.
So?
What do you want your car to do?
If you're gonna keep the Sportlines, then depending on what you want your car to do, your options will be somewhat limited.
Your car is too low on the Sportlines for the shocks to truly work correctly, save for the 1/4 mile, and your car will not take the turns well.
Now, all what I just typed is subjective...you have a few folks here on sportlines and factory shocks who SWEAR that they have a great handling car...
they probably never rode in a 4th-gen with Koni shocks
frrax.com , lots of f-body owners who auto cross and roadrace.
Now if you want to build your suspension for the 1/4, then go to ls1tech.com in the suspension section, you can ask questions there.
Remember, your f-body can be setup to EITHER be great doing the 1/4, OR be great doing the twisties, NOT BOTH.
If you try to compromise to do both, then that's just what you get...A COMPROMISE.
Good luck.
