Once you've fitted a aerodynamic kit on your vehicle, many owners notice that the door sections no longer open or close smoothly. This problem often results because the updated fender liners, rear quarter panels, or modified body parts change the clearance around the door jamb, resulting in contact, sticking, or off-center positioning. Correcting door fitment is a vital maintenance to ensure safe and proper operation.

First, check the whole edge of the door in its sealed position. Scan for any rubbing zones between the door and the aftermarket components, especially near the hinges, latch side, and lower edge. Open and close the door slowly while observing for signs of resistance. Should you observe, paint scuffing or abnormal effort, that’s a definite indicator that adjustment is needed.

Next, check the hinge bolts. Partially unscrew a wrench, but do not take them out entirely. Adjust the door up, down, forward, or backward as needed to improve gap alignment. You may need a second person to keep alignment steady while you resecure the hinges.

Insert adjusters if the gap is uneven or if the door is lower than intended. Position durable plastic inserts between the hinge mount and chassis. This allows you to achieve exact spacing. Confirm fitment after fastening.

Check the latch mechanism to make sure it closes properly. If closing is difficult, the door may be shifted too far inward or uae auto part outward. Tweak slowly and cycle the door multiple times.

Be sure to check the rubber gaskets and gaskets after making changes. Ensure uniform pressure and not under tension.

When all components are correctly positioned, perform several opening under real-world scenarios—like after cold weather exposure—to ensure the clearance holds up.

Should adjustments prove insufficient, consider filing a minimal section from the contact zone with a Dremel, but only as a last resort. Use a template before removing material.

Correct door fitment not only improves aesthetics but also prevents long term damage to exterior coating, weatherstripping, and mounting hardware. Take your time, follow a step-by-step approach, and resist the urge to hurry.
