if your looking for sway bars on a budget (i assume front and rear), then the cheapest and probably the best way to go is to get a front sway bar from a E30 convertible (21mm) and buy some M3 mounts and links, you'll have to weld the M3 mounts to the strut, buy it will serve you much better than a aftermarket bar such as Suspension Techniques 22mm sway bar linked to the control arms. for the rear, try to find one off a e30 m3, i forget the exact diameter but i know its about 1.5mm thicker than the stock bar. if you plan to go any bigger for the rear then you will reinforcement mounts that bolt through the trunk or else it will tear out the existing mounts sooner or later.
if you decide to go aftermarket then check out:

and Suspension techniques
You dont really need a thicker front one. That will just tighten up the roll some, make the car whip a little more, but it will also make more understeer.
Just go for the rear ones. Also if you want to do drift, your gonna need a pair of 205s up front and 195s with stiff tire walls in the back. The best ive found in 195s is BF goodrich. They make this one tire that has incredibly thick sidewalls and only costs $58.
The more wieght you get out of the front the less counter balance there is for the rear. Less wieght up front = rear end will kick out easier.
If your gonna drift, fill up the gas tank. It adds a lot of extra kick out inertia. Keep the tire in the trunk too.
I have never had experience but im assuming its harder to drift with a open differntial than a limited slip one. So invest in a LSD if you dont have one. get one from a junkyard
Thats all i can think of for now

I live my life one quarter mile at a time, and for those 23 or more seconds I'm free.
Again, I must thank you for the input. I want to keep the car
well balanced as sometimes drifting requires all 4 wheels (sometimes), but
you are right, I need an LSD but I am only gonna buy that when I am
Thanks for the junkyard idea, Im gonna look into it!!!
Ireland Engineering has a 22mm adjustable rear bar with their specially designed reinforcement mounts for about $250, and i dont think it would be worth it to stiffen up the front if you intend on drifting, like fox said. also, are you sure you dont already have a LSD, they were a option in 85
