How Do I Fix This?
I was autocrossing last weekend and I got some of the pictures that were taken today. What can I do with my completely stock suspension to fix this body roll? Or is this normal?

coilovers and some 28mm & 22mm sways will surely reduce that

I recall reading a magazine article when the 88 S came out, and they loved the car but noted they could actually get it to scrape when autocrossing. I think it's normal for stock suspension and good reason to firm things up....

Bigger sways, harder bushings, and lower the car a bit if it's still stock height. Those are the least expensive and simplist things to do. If you suspect your shocks to be soft, that won't help either.
Beyond that, stiffer springs will make a big difference, but to eliminate roll, you'll sacrifice street comfort.
My 924S pictured below is a lighter car than 951, and those pics were taken with new HD Bilsteins on 4 corners, 250lb front springs, car lowered 3/4-1", 26.8mm front and 19mm rear bars, urethane bushings on both bars and 968 caster blocks up front. The car drove great, but it still had some roll. The only thing left to do would be to increase the front spring rate and install coil-overs in the rear to stiffen things up.

I have seen this done by using heavy sway bars set to very stiff (weltmeister) with stock springs. While that will reduce the roll, sway bars are meant to be a supplement to springs, not an alternative. You would be putting huge forces on the end links, and I've seen these break on at least three cars, resulting in snap oversteer. Consider at least somewhat stiffer springs in addition to heavier sway bars.

I have already lowered it to the level that I really like. The ride is just the way I like it; comfortable in town but I can feel what I need to when I drive. I am just trying to keep that ride but lessen body roll.
So my question is if there is a fix, i.e. sway bar or strut tower brace, that could lessen it without dramatically changing the ride in normal driving?

That is likely 26.8mm front sway, 18mm rear sway, and I believe 180 lbs front springs.
Are your shocks original/unmolested? They could be getting soft of they are. The Sachs on my 924S were soft and the car would plow through corners until I replaced them. I upgraded bars first because that was easy, but shocks made a huge difference for me.

+1 for MO30 sways front and rear. consider 250lb Weltmeister lowering springs and lowering via the eccentrics at the rear - but if you like your car as is just try the sways first - the best thing about this is it is idiotproof (and easily reversible) - I know because I actually did it myself.
Do NOT mess with the bushings.
The effectiveness of a tower brace is questionable but it is a cheap/easy mod and at worst does nothing.
