Mustang still handles like an Ox Cart after many upgrades, why?

What shocks do you have? If you don't have Konis I suggest getting some. If you want to go all the way some coilovers would be awsome.

Another huge thing is your tires. What tires are you running??

You'd notice a big difference with a panhard bar, MM makes one that fits with full exhuast. Coil overs would help as well.
The steering slop is due to the rack, a solid steering shaft may help a tad, but there will still be play. Flaming river makes a power steering rack that is supposed to get rid of it, it's on my upgrade list.

I had the Tokico shock/strut/spring kit installed. Rides nice and handles well.

got a 88GT so far i have installed eibach pro kit, steeda strut tower brace, 2 point lower brace, full lenght subframe connecters 4pt, upper and lower control arms, welded torque boxes etc.. replaced wheel bearings, and bushing in the front with polyurethne bushings. the steering has some play in it when you move the wheel it moves a little first before the car moves and makes a humming noise when doing so, i replaced the power steering pump already. what can i do next to make it handle????

Well,
It could be your steering rack is shot. How many miles are on it?
Check your steering shaft, That is the piece between the firewall and steering rack. The bushing could be shot and give you that play in the steering wheel. As for the other parts, you are doing a good job of up-grading your suspension on a 16-year-old car. But I think you are missing a few key parts.
One for starters is you need a set of caster/camber plates. That will allow you or the suspension tuner to dial in more camber and caster than factory settings.
What did you do for new shocks and struts on your car?
After you installed the springs, did you have the car re-aligned?
What about the ball joints and bushings on the A-arms?

Get a heavy duty rear sway bar along with the control arms. Then spend $ on a good set of tires.

DO not get Kumho Supra Ecsta's up front, you will regret it, just do nitto 555's all around. There are plenty of better tires though, they cost $$$$.

I am tired of expensive crappy tires myself and since the car is my sunshine car I'm just gonna put VictoRacers all the way around.. That should take care of it

check the rag joint on the steering rod.

These are the most important parts you've left out. The shock absorbers job is to keep the tires planted to the road. If you don't have good ones, they won't. If you don't have good tires, it doesn't matter what else you do.
Everybody pretty much covered the steering issues/fixes already; I'll second the vote for a panhard. A GT witha fresh stock suspension and panhard can outhandle your average spring/shock modified car. The lack of positive location of our rear axle is one of the main problems with the fox suspension. If you have a GT you don't need a stiffer anti-sway bar yet, there are more important things to do first- like the shocks, c/c plates and panhard. Not to mention tires! If money is an issue, I've had good luck with Nitto 450's. V rated, cheaper than the 555's, wear better, last longer, better in the rain. Best, you can get them in a 16". I think last time I paid $350 for all four.

How are they in the rain?

3PSI deviation from proper tire air pressure will affect handling.

No car will handle well if the driver is not smooth with the wheel.I'm not sayin you crank on the wheel like its a 18 wheeler but try drivin smoother not fast abrupt turns but slow and calculated ones.A loose wheel could be the tie rod ends(very cheap).
