Installation matters as much as the part.

This page covers the general installation of carbon fiber parts (lips, hoods, grilles, mirror caps, diffusers). Exhaust systems and intake kits have their own guides. Whenever you get stuck, ask us on WhatsApp.

Recommended: professional fitting

Every part is OEM-fit, but surface prep, careful alignment and the right torque call for workshop discipline. Message us on WhatsApp to ask about a workshop near you.

If you want to fit it yourself

With some mechanical experience, parts like mirror caps, front lips and wings can be fitted by following the steps below. For structural parts such as hoods, grilles and diffusers, we especially recommend professional installation.

Steps

The five-step general flow.

Every product installs differently. Your part's installation steps are in the description on its product page; this page covers the basics.

  1. 01

    Preparation

    Let the car cool down on a flat, shaded spot. Avoid fitting onto hot surfaces (especially the hood and around the exhaust) before the car has cooled; thermal expansion can cause fitment issues during installation.

  2. 02

    Dry fit

    Place the part on its original mounting points without tightening and check that every point lines up. If any mounting point is off by more than 5 mm, stop and contact us on WhatsApp for a replacement.

  3. 03

    Surface preparation

    If you are replacing an existing part, remove all adhesive residue left by the old one. If the part is new, clean the mounting surface thoroughly with isopropyl alcohol.

  4. 04

    Installation

    Tighten screws and bolts to the recommended torque values. Over-tightening can crack carbon fiber parts; on other parts it causes poor seating.

  5. 05

    Final check

    Avoid high speeds for 24 hours after installation. Check the parts for play and vibration over the first 50 km.

Tool list

The basic installation kit.

  • Torque wrench (5-60 Nm range recommended)
  • Torx (T20, T25, T30) + hex (3, 4, 5 mm) set + flat and Phillips screwdrivers
  • Isopropyl alcohol (≥90%)
  • Microfibre cloth
  • Plastic trim removal tools (to avoid scratching paint)
  • Gloves (skin oil weakens adhesives)

Critical warnings

These three mistakes cause damage the warranty does not cover. Knowing them in advance is cheaper than buying a replacement later.

  • Caution

    Mounting close to the exhaust / manifold

    Prolonged heat exposure degrades the resin and the clear coat of carbon fiber parts. Use a heat shield or reflective tape to prevent it.

  • Caution

    Bonding to fresh paint

    If the car has just been painted, avoid VHB tape for the first 30 days. The adhesive works its way under the paint and can lift it when the part is later removed.

  • Caution

    Modification

    Damage caused by drilling, cutting or other modification is not covered by the warranty. All our parts fit the OEM mounting points one-to-one.
