Learn how to quickly install the Sport Car Top Carrier on your vehicle, with or without a roof rack. Step-by-step instructions for a secure, waterproof cargo setup.

Quick Answer

Attach the Sport Car Top Carrier to your vehicle using the roof rack straps or, if no rack is present, the included Car Clips that grip the door frame weather molding. The whole process takes about 10 minutes.

What You Need Before You Start

The Sport Car Top Carrier comes with all necessary straps and Car Clips. No tools are required. Make sure your vehicle's roof is clean and dry, and that you have enough space to lay the carrier flat before loading.

Roof Rack vs. No Roof Rack: Key Difference

If your vehicle has a roof rack, you can thread the straps directly around the crossbars. If it doesn't, the Car Clips hook onto the rubber weather molding around your car's door frames. Both methods are equally secure when done correctly.

Step-by-Step Installation

Position the Carrier on Your Roof: Lay the carrier flat on your vehicle's roof, centered side-to-side and front-to-back. Make sure the opening faces the rear of the car so wind doesn't catch it during driving. Common mistake: placing the carrier too far forward can block your view or interfere with the sunroof.
Attach the Straps (Roof Rack Method): If you have a roof rack, open the carrier and thread each strap over the crossbar, then back through the buckle. Pull tight so the carrier is snug against the rack. Check that the strap is not twisted – a twisted strap can loosen during the drive.
Attach the Straps (No Roof Rack – Car Clip Method): Clip the Car Clip onto the rubber weather molding of your car's door frame. Close the door over the clip. Then thread the strap through the clip and tighten. Make sure the clip is fully seated on the molding and the door closes completely. A partially closed door can leak or damage the seal.
Tighten All Straps Evenly: Pull each strap tight, alternating sides to keep the carrier centered. The carrier should be firm against the roof with no loose fabric. Over-tightening can dent a soft roof or damage the carrier's seams. Stop when the carrier is taught but not stretched.
Secure Excess Strap Length: Use the built-in strap keepers or a rubber band to bundle any extra strap length. Tuck the bundle under the carrier or tape it down. Loose straps flapping in the wind create noise and can fray against the car's paint.
Load Your Gear and Close the Carrier: Place items inside, distributing weight evenly. Zip the carrier closed and double-check that the zipper is fully sealed. The waterproof cover will keep contents dry. Avoid overloading – the carrier is designed for lightweight cargo. Heavy items are better stored inside the vehicle.
