When i received the package and opened the box, the sliders were loose out of the actual packaging like on the product pictures. After further inspection i noticed there were some substantial scratches in some areas of the sliders. I'm not sure if this was caused by the sliders coming out of the packaging and moving freely during transit or if this were a returned item and sold as brand new which would also explain the opened packaging. They are fully functional and work great, not as smooth as i was hoping but they get the job done. Also, once mounted, there's some noticeable slack on the rails themselves. Depending on the use, this might not be the best thing as it causes some flex/movement under heavy breaking, i have yet to fully test them under racing conditions. The Sparco brand kinda sucks. Their website tells you very little information for mounting. I bought a Sparco R333 that i installed these on and the sliders don't come with mounting screws (+$20) and if you're mounting this directly to the bottom of your seat you also need the slider spacer kit (+$12). Again, none of this is mentioned under normal product description or even on their website. I simply went to the hardware store and got the screws it needed and some metal bushings that work as spacers but the lack of description to tell you everything you would need to actually mount the seat with sliders so you can order it all together really sucks!
