I while ago, I won an auction on EBay for a set of Fully Adjustable Race Application Upper Control Arms. They were designed for a Supra TT but should bolt directly onto the SC. The control arms allow for complete camber and toe adjustment. I like them because you can make all the necessary adjustments with the turn of a wrench. It would work best for somebody who plans on taking their car to the track or autocross, or if you plan on lowering your car and are worried about camber gain. I was planning on using them on my SC400 since I frequently take students out on track orientation sessions, but decided to just keep the car stock instead. I have a picture of the same ones mounted on a car that I can email if you're interested. Mine are brand new, never mounted. I'm asking $375+ shipping.
