Professional Installation Recommended Side skirt installation is one of the more involved exterior modifications. Euroforge strongly recommends professional installation. Incorrect fitting can result in damage to the vehicle's sill or loss of the part at speed. If you are unsure at any stage, stop and consult a professional.
01

Align & Confirm Fitment

Hold the side skirt against the vehicle sill to confirm it sits flush along its full length. Check the front and rear ends align with the front splitter and rear diffuser or bumper edges, and that the top edge follows the body line cleanly.

NoteSide skirts are handed — ensure you have the correct skirt for each side (left / right) before starting. They are not interchangeable.
02

Raise the Vehicle

Jack the vehicle at the appropriate jacking points and support on axle stands, or use a workshop ramp. The vehicle should be raised enough to comfortably access the full length of the sill from below. Fit one side at a time.

SafetyNever work under a vehicle supported only by a jack. Always use axle stands rated for the vehicle's weight. Apply the handbrake and ensure the vehicle is on level ground.
03

Clean & Dry the Sill Surface

Thoroughly clean the full length of the vehicle sill using isopropyl alcohol (IPA) and a clean lint-free cloth. Clean both the vertical sill face and the underside lip. Allow to dry completely and repeat with a second fresh cloth.

NoteSills accumulate significant road grime, wax, and undercoating overspray. Take extra time on this step — the adhesion quality of the 3M tape depends entirely on a clean, dry surface. Two thorough cleaning passes are the minimum.
04

Assemble Multi-Piece Skirts (If Applicable)

If the side skirt is supplied as a multi-piece kit, assemble all sections using the included fixings now, before fitting to the car. Tighten permanently so the skirt is a single rigid unit.

NoteAll sections must be fully connected before mounting to the vehicle. Do not attempt to join sections after the skirt is fitted to the car.
05

Apply 3M Tape & Heat to Activate

Apply the included 3M double-sided tape to the back face of the skirt, only in areas where the skirt makes direct contact with the vehicle sill. Do not run tape across non-contact or unsupported sections.

Once applied, warm the tape with a heat gun or hair dryer on medium for 30–60 seconds per strip, keeping the heat source moving.

Warning — Keep Heat Source MovingHolding the heat source too close or stationary can damage the skirt finish — causing paint peel, lacquer bubbling, or warping. Maintain a minimum of 15 cm distance. Use a hair dryer on medium if unsure.
Important3M tape is a positioning aid and secondary retention layer — not the primary fixing method. Mechanical fixings must always be used. Never rely on tape alone for side skirts.
06

Fit Skirt to Vehicle & Secure with Fixings

Press the skirt firmly against the sill along its full length. Then, using the pre-drilled holes in the skirt as a guide, drill through the sill and fix with the included screws. Some models use bolt-replacement fixings that thread into existing factory sockets underneath.

Fixing method — check which applies to your kit
Screw Fixing (Standard)

Pre-drilled holes in the skirt guide drilling into the sill. Fix from below with included screws. Tighten snugly — do not overtighten.

Bolt Replacement (Some Models)

Factory bolts on the sill underside are removed first. The skirt locates over these positions and the supplied bolts thread into the existing factory sockets.

NoteInstall all fixings loosely first, then tighten from the centre outwards. A bead of automotive silicone sealant at the top edge seam provides additional hold and seals against water ingress behind the skirt.
07

Final Check

Lower the vehicle and inspect the skirt from the side. It should sit flush along the full sill with no gaps, no sagging at the centre, and no movement when pressed at any point. Repeat the full process for the opposite side.

NoteRe-check all fixings after the first 100 km. Road vibration can cause initial settlement. Inspect the sealant line at the top edge — reapply to any gaps before they allow water ingress.
Legal & SafetyModifications to aerodynamic components may affect your insurance and should be declared to your insurer. Ensure ground clearance remains within legal limits for road use. Euroforge accepts no liability for damage arising from self-installation. Professional installation is always strongly recommended.
