Yah do some homework... it's common knowledge that the SC300 and the IS300 as well as the MKIV Supra are all riding with the same chassis, the same Engine, the same suspension ETC. Only thing that makes these cars different is their bodies, I used to own a 95' SC300 and when my Tien coilovers came in the mail the shock bodies said "SUPRA 1995" and yet they had perfect fitments. You should look up the Supra TT brake swap for your car, its a good upgrade. Seat rails in all 3 models are the same. Why do you think the parts are so interchangeable?? I own a LS400 and seat rails are MUCH harder to find than yours. Corbeau is the only company out there to offer OEM sliders for my car.
