The IDS Rear Drag Coilover Kit for the S13 and S14 Silvia / 200SX features a very strong bolt on 3/16″ thick upper adaptor mount, and coilover with polyurethane mounts that are custom built to spec for IDS.
Please pick a spring rate and valving option that best suits your setup, feel free to contact us if you are unsure of the spring rate for your application as we are happy to assist.
NOTE: The drag kit requires a small amount of clearancing on the knuckle to clear the shock body. This is outlined in the provided instructions and is very easy to do. All IDS S-Chassis coilover kits require the use of an aftermarket tube style rear upper camber arm.
