Adding the kinks and different bends isn't necessary unless space and/or mounting location dictate it.

Lets not forget an FSAE car weighs ~500lbs and will likely not be used at speeds over 60mph. My point? If it breaks, oh well.
If a sway bar breaks on your 944/951 when you're at the edge of traction...it wont be a pretty sight and you wont be saying "oh well."
To echo everybody else's thoughts: It is certaintly doable with enough knowledge and the proper tools, but you have to ask yourself if its worth your time and the risk?

When a swaybar is installed on a 944/951, it is desired that it be installed when the car is at its static ride height (car sitting there on the ground).
This is done so that there is no (or very little) pre-load.

Sway bars are not preloaded. At least not in purpose. That is why competition bars used adjustable drop links. The idea to REMOVE all the preload. Preloaded sway bars cause inconsistant spring rates when turning right or left. Stock sway bar have not provision for preload adjustments. Even M030 bars do not the ability to remove preload.
FSAE is an example where "off the shelf" is not avalible and learning is important. So design and build your own sway bars. Of course they also design and build the entire chassis too.

Too many people just look at the cost or raw materials and think they're getting ripped off. It's the R&D, machinery, storage and shipping that cost.
Sure you could make one that might work, but it would never work as well as a professionally manufactured one.
Why don't you just buy a used one?

Caroll Smith has an excellent write up on sway bars in one of his books. There is a certain steel alloy that works best; heat treatment, diameter and bore size are also critical. There does exist a demand for different bars than we have currently available, especially cockpit adjustable drop link sliders... (hint, hint to any of the vendors). However, unless you are up on the metalurgy, and heat treatments, I suggest you buy what is already available.

I was just pointing out though that you could make alot of stuff for your car, IF you know what you're doing and have the often expensive tools. Most people do not really know (as most people don't have engineering degrees), and don't have multi-thousand dollar machining tools.
