Whoa there Nelly. for maximum drop, the sportline kit is good however the spring rates are far too low for decent handling. The pro-kit is actually better for handling then the sportlines when matched with proper shocks. As far as handling goes the pro-kit ain't bad, but I wouldn't call them the best until we know what his suspension goals and reasons are.
There are other kits out there for those wanting even better performance. even with 600+ lb/inch springs on the front the ride isn't that bad... and there are a couple of coil sets out there with spring rates in that ballpark.
The first thing you need to ask yourself is what you want to do with your car (autocros, road racing, drag racing, pure street, show, or some combination).
The second thing is to decide how much to spend. A fully adjustable full coil over setup with matched swaybars, panhard rod, control arms, and bushings will offer the most potential but at the highest cost.

The sportlines are the lower springs with higher spring rate...
Just thought I'd clear that up.
PS
I've already called payams sportlines...

For what it's worth I've been told that as a rough rule of thumb for every inch the spring is shorter than stock it should be at least 20% stiffer.So for a spring 2" shorter should be aprox 40% stiffer. So the guys are correct cutting coils is just not a good idea.
Just my $0.02 worth.
PS. If you want to set your car up to handle as good as it looks go over to LS1.com and read some of the posts in the Autocross forum.

The sportlines not only have more drop, they have lower spring rates. This makes them much more likely to bottom out (especially with stock decarbon shocks), and they will have less roll resistance

...Kal..Twitch's springs are pretty much new..and he never races his car
...so if you choose to buy the sportlines that would be fine...but Craig is right they will bottom out..then again they will look sweet...really think about this, I've heard some people complain about the results...Mike

The pro kits are designed for a balance of handling and road manners.
The sportline have increased spring rate over the pro kit for handling.

I've been in cars with pro kits and sportlines, and I must say the pro-kits have near stock ride feel until you get into the twisties. They are very progressive. my friends Supercoupe feels like a limo until you drive it hard.
The sportlines on the other hand are very firm and give the car a racelike feel

Maybe the supercoupe versions are setup differently....
The problem with these comparisons is that a car's handling is about much more then the springs used. Shocks, swaybars, bushings, control arms, chassis stiffness, camber control, weight distribution, rear suspension/driveline style (3-link, 4-link, axle, IRS, etc.) and tires all play a role in determing a car's overall handling prowess. And even then a setup tuned for autoX may not be optimal for a Road Race.
In the reading I have done on the autoX forums here and on LS1.com, most people agree that the Sportlines are simply too soft for F-bodies. However I am sure that if you wanted to you could match the other suspension components and make the Sportlines work well.

I had the Pro-Kit installed in my Z28 for 2 months before getting the Sportlines. The Pro-Kit was definitely more aggressive...the ride height was about 1.25" lower than stock. With the Sportlines, I had more performance over stock, but not nearly as much as the Pro-kit. The reason why I changed to the Sportlines was becuase I needed a bigger drop to complement the 18" Vette rims and the GFX kit .
Damn I miss my car
