The calipers came off a 93 Silvia but will fit any S13 model 240sx. It is slightly bigger than your normal front S13 brake calipers and is great for an upgrade if you are on a budget. It also comes with Earl's stainless steel brake lines which are also used but in working condition, I Bullsh** you not. I am asking for $150 OBO. You can E-Mail me at MaDDs7yLeS13@yahoo.com.
