For MK7 Fiesta ST owners chasing wider track, aggressive stance or track-day clearance - not just 'wider arches' - these AIRTEC fibreglass extended wheel arches deliver real fitment intent.
Front arches: Designed for MK7 ST with standard front bumper; require light trimming on non-ST models (no cutting needed on ST)
Rear arches: Fit all facelift MK7 Fiesta (ST and non-ST) without modification
Stage 1+ fitment ready: Clear 255mm+ tyres on lowered STs with modest camber; tested with 18x9.5 ET35 + 245/35R18 setups
Fast road & track day use: Fibreglass construction balances weight, rigidity and repairability - no brittle polyester resin
Show car or daily driver: Smooth gel-coat finish, ready to prime and paint; fits OEM arch liners where retained
