Why buy from us

We run these Maxton Design rear corner trims on our own builds and customer cars, and feedback has consistently praised the fit, finish and overall quality. The ABS material offers a reliable balance of rigidity and resilience, and once the protective film is removed the deep gloss looks superb next to OEM gloss black parts.

Fitting service

Professional installation is recommended to ensure correct alignment and secure mounting. MJ Modifications offers fitting at our Warwickshire workshop. Request a quote at info@mjmodifications.co.uk.

Care and preparation

Items arrive with a thin protective film to safeguard the finish. Remove this after test fitting and final prep to reveal a clean, high gloss surface. Always trial fit before drilling or fixing.
