The rear does not have springs, the twist of the torsion bar is the "spring" that is why a larger bar is equal to a higher spring rate. So you have torsion bars, shocks, and sway bar to make up the rear suspension. There are also the bushings (stock, delrin, metal) as a nice "while you are there" kind of job. I have done torsion bars on a few 944/924 cars now (and it usually takes more than once each time to get it right. This is not a cheap task nor is it for the faint of heart. Just getting the 24mm and 30 mm bolts off is enough to stop many, but doing the geometry to get the height right and the car level does most of the rest in.
Bottom line is good shocks all around, adjustable sway bars all around, 200-250 springs up front, fresh bushings, matched tires and rims, and a good alignment will net you the most satisfaction. If you do choose the 30mm torsion bar route, and still drive on the street make sure your significant other has lots of sports bras!
