Rally style mudflaps are one of the most popular exterior modifications on the Focus ST225, and for good reason. The ST never came with OEM mudflaps from the factory, partly because the sill profile made a stock fitment difficult. That left the arch liner and lower paintwork exposed to road debris, stone chips, and spray. A precision-fit aftermarket set solves that problem properly and finishes the look of the car in a way that cheap eBay alternatives simply do not.
If you’re not sure what separates rally style mudflaps from universal panels, see our guide to the difference between universal rally mudflaps and rally style mudflaps.
This guide covers everything you need to know before buying: fitment compatibility across Mk2 and Mk2.5 variants, the lowered car question that comes up constantly on Focus ST forums, and what to expect from the PolyWard kit specifically.
Which Focus Mk2 models does this kit fit?
The PolyWard Focus Mk2 rally style mudflap kit fits all Mark 2 and Mark 2.5 Ford Focus models built between 2005 and 2011. That covers:
- Ford Focus ST225 – all years, pre-facelift and facelift
- Ford Focus Mk2 Zetec – all variants
- Ford Focus Mk2 S
- Ford Focus Mk2.5 facelift models- same kit, same fit
The pre-facelift Mk2 and the Mk2.5 facelift share the same arch liner mounting points and arch profile, so one kit covers both generations without modification. If your V5C says 2005-2011 Ford Focus, this kit fits.
The Focus RS Mk2 is a separate product, as the RS has a different arch profile and wider bodywork. See the Ford Focus RS Mk2 rally style mudflap guide here.
Fitting: what’s involved
The kit uses the existing arch liner mounting points, so no new holes need to be drilled into the car’s bodywork. The front mudflaps use the existing screws in the inner arch liner. The rear mudflaps use the existing fixing points on the rear arch liners.
What’s included in the kit:
- 2 front mudflaps and 2 rear mudflaps, shaped specifically for the Focus Mk2 arch profile
- All required brackets and fixings
- Printed fitting instructions
Fitting all four corners takes most people around one to two hours on a first attempt. Removing the wheels gives better access to the arch liner mounting points and makes the job significantly easier. It is possible with wheels on, but access is tighter.
Detailed guidance on what to expect when fitting PolyWard rally style mudflaps to any car is covered in the PolyWard rally style mudflap fitting guide, and the vehicle-specific printed instructions are included in the box.
The lowered car question – what you actually need to know
This comes up on every Focus ST forum thread about mudflaps, and the honest answer is more nuanced than most sellers give.
On a standard height car, there is no issue; the mudflaps sit correctly above the road surface with adequate clearance.
On a modestly lowered car with about 10 to 20mm drop, there is usually still no issue. The clearance reduction at that level of drop is minimal, and the mudflaps should clear road surfaces without catching.
Where it gets more specific:
- 20-30mm drop: We trim approximately 10mm from the bottom edge before dispatch
- 30-40mm drop: We trim approximately 20mm from the bottom edge before dispatch
- Aggressive or slammed fitment: we trim 25-30mm from the bottom edge before dispatch
This trimming service is free. If you’re ordering a set for a lowered Focus ST225, just mention your approximate drop in the order notes, or contact us via email before checkout. Please specify your drop in millimetres, and we’ll trim the flaps before they leave the workshop. The trim comes from the bottom edge only and does not affect the arch liner fitment or the top fixing positions.
The forums are full of posts from ST owners who fitted mudflaps and then had to trim them down themselves after scraping speed bumps. The trimming service means that the job is done before the kit arrives.
Material and specification
PolyWard Focus Mk2 rally style mudflaps are made from 4mm PVC throughout. There is no 3mm or budget option; there is one high-quality specification, consistently applied across the range.
4mm PVC at this thickness is flexible enough to deflect on impact and spring back without cracking, while being rigid enough to hold its shape and sit correctly against the arch profile. It handles UK winter conditions without brittleness and resists the oil, grit, and salt that lower panels are exposed to year-round.
The material meets Motorsport UK thickness specifications, not because these mudflaps are intended for competition use, but because 4mm is the correct material specification for a product built to last rather than to hit a price point or squeeze extra margin out of customers by skimping on material thickness.
Rally style mudflaps are legal on UK roads and pass the MOT when correctly fitted. For the full details, see our guide to aftermarket mudflap legality in the UK.
Colour options
Four colours are available: black, red, white, and blue.
Black is by far the most popular choice on the ST225; it works against every exterior colour the Focus Mk2 came in and reads as a purposeful, factory-adjacent fitment rather than an aftermarket addition. However, all colours have their fans, and if you have a unique build or strong colour styling, there is an option for you in our range.
Logo options
Ford ST badge logos are not offered — using manufacturer badge artwork is copyright infringement, and any supplier offering official-looking ST logos on mudflaps is operating in legally grey territory.
PolyWard mudflaps are available in two options:
Plain: solid colour throughout, no logo. Clean, subtle, works on any car regardless of specification or personal preference. The material takes decals and stickers well, so if you do want to source a logo or decal from elsewhere, it is a two-minute job to stick to the plain coloured mudflaps.
PolyWard logo: two variants available: the small P mark or the full PolyWard text logo. Both are available in multiple colours across all four mudflap colour options, so a black mudflap can have a white, red, blue, or orange logo depending on what works best against your car’s colour.
The plain option is the most popular choice for owners who want the look without any branding visible on the car.
Delivery
Orders placed before 3 pm ship the same day. Standard delivery typically arrives in 3-4 working days. Express shipping is available if you need them faster; express orders arrive within 2 working days.
This is worth knowing if you’re comparing options. Made-to-order mudflap suppliers in this category typically operate on lead times of 10-14 working days as standard. PolyWard mudflaps are in stock and ship immediately.
Why the Focus ST225 never had OEM mudflaps
Ford never produced OEM mudflaps for the Focus ST specifically. The combination of the ST’s side skirt profile and lower sill line made a clean factory fitment difficult; the geometry that gives the ST its purposeful stance is the same geometry that ruled out a straightforward OEM mudflap solution.
That’s why the aftermarket option is the only real route for ST owners who want proper arch protection. A precision-fit aftermarket set designed specifically for the Mk2 arch profile solves what Ford left unresolved. Done well, it looks better than any OEM option would have anyway.
