Stock Suspension, school me please!

I'm currently building up an '83 Fox and have a few questions I need an experienced hand at. The car should be capable of a low 10 second pass, and i'm curious as to what all I should be paying attention to suspension wise. It's a T Top/Hatchback car.

What is the stock suspension capable of? This is assuming only subframe connectors being the only add in part. I will NOT be leaving off of a transbrake, and it's an automatic car. I have almost the biggest slick you can fit without modifying the wheel wells underneath it now.

About the T Top car in general. How much can the T car's take power/et wise? I'm assuming because they are an aftermarket conversion unlike the convertibles, they appear to be a less stiff chassis.

Rick, thanks for the help.

So, for sure tq box reinforcements, upper/lower LCA's. On the front, i'd really like to shy away from coil overs if it's possible. I don't think the car will leave too hard as it doesn't have a trans brake and is turbocharged.

As far as the cage, yes you are absolutely right there. Our track is NHRA Sanctioned and therefore I must abide by the applicable safety rules also, which start around 11.5 with the 10 point I believe at 9.9ish or so.

My plans are to get the car stable enough to make a pass, and do the necessary safety upgrades for whatever E/T it runs, as i'm just not entirely sure yet.

How about the T top cars in general. With welded subframe connectors, how do you think this car will take dragstrip life? I know they are a hacked aftermarket conversion from the factory, no other bracing other then where they cut the roof at for the T's. The convertibles have a lot more bracing than these cars did.

Thanks for the advice guys. I've almost got the car ready for the street/strip, so I will be looking into doing those items shortly.

Here's a few pics of the pile, please don't hate too much on my motor choice
