If you want sway bars then persumably these customers are going to open track events. You know what they would also value? A nice set of cold air ducts to the front brakes. On the track as we all know (or should know by now) the weak link of the car is cooling to the front brakes. My home made models from Ace hardware store allow for 2-3x more laps without the brale idiot light coming on. Proper made brake ducts that funnel air to the back of the caliper would increase this even more.

What do you say about taking the existing heat shields on the back of the front rotors off, fixing a brake duct hose assembly and making them available?
