Triple R Composites Ford Focus MK4/4.5 ST Spoiler Lip
Give your Ford Focus MK4/4.5 ST a sharper, more purposeful rear end with this Triple R Composites spoiler lip. It extends the factory spoiler for a cleaner, more aggressive look without being over the top.
This spoiler lip is designed to work with the airflow over the back of the car. By adding a subtle extra edge to the original spoiler, it can help improve high speed stability and reduce some of the lift at the rear. The result is a car that feels more planted, while also looking more like a focused hot hatch.
- Sportier, more aggressive rear profile while keeping an OEM style finish
- CAD designed from full vehicle scan data for accurate fitment
- Manufactured in durable Nylon 12 using SLS 3D printing for strength and consistency
- Media blasted and black coloured for an OEM bumper trim appearance
- Supplied in click together sections that mount to the factory spoiler
- Uses polyurethane adhesive for a strong, long lasting bond
Design and materials
The spoiler lip is CAD designed using detailed scans of the Ford Focus MK4/4.5 ST. CAD is computer aided design software that allows very precise shaping, so the parts match the lines of the original spoiler and bodywork.
Each section is 3D printed on an SLS machine in Nylon 12. SLS, or selective laser sintering, is a process that uses a laser to fuse nylon powder into a solid part. This gives a strong, light component with consistent thickness and detail, ideal for exterior trims that see regular use and changing weather.
After printing, the parts are media blasted and finished in black. This creates a subtle texture and colour similar to OEM plastic bumper and trim parts, so the spoiler lip looks like it belongs on the car from the factory.
Fitting information
The spoiler lip comes in sections that simply click together before fitting. It is then bonded onto your existing Focus MK4/4.5 ST spoiler with a polyurethane adhesive. Polyurethane adhesive is a type of strong automotive glue that stays slightly flexible, helping it cope with vibration and temperature changes.
Professional fitting is recommended if you are not confident working with bonded exterior parts.
This part is designed to fit Ford Focus MK4.5 ST models from 2021 to 2025 that have the standard factory spoiler.
