AB Customs is a tuning and customisation workshop on Lady Margaret Road, Southall. We remap ECUs, integrate smartphones, fit dashcams and cameras, and style cars the way their owners actually want them.

AB Customs started the way most good garages do — one enthusiast, a laptop and a queue of mates wanting more from their cars. Word spread through West London, the jobs got bigger, and the unit on Lady Margaret Road became home.
Today the bench handles everything from a Stage 1 map on a daily diesel to full styling builds: wraps, de-chroming, carbon trim, exhausts and suspension. The same person who quotes your job is the one who does it.
Our builds are shared at @abcustoms.uk — before and afters, dyno runs and the odd pop-and-bang clip. Come and see the work before you book it in.




Every map is written for your car, your fuel and your driving — never a generic file flashed off a laptop.
If a mod won't suit your setup, we'll say so. We'd rather keep you as a customer than sell you the wrong thing.
Wiring tucked, trims refitted properly, nothing rattling. Our fit work is meant to look factory.
A real workshop on Lady Margaret Road with a phone that gets answered and messages that get read.
