Golf Mk4

The Mk4 Golf is one of those platforms that just keeps giving. Whether you're running a 1.8T, a TDI or a VR6, there's a reason this generation still has a massive following. Not only is it tunable and robust, but it rewards every upgrade you throw at it.

We've been supplying Mk4 Golf parts since these cars were rolling off the line. Our warehouse carries over 670 products for this platform: coilovers, big brake kits, induction kits, exhausts, remaps and more. Every part comes from brands we trust and use ourselves, because we don't stock anything we wouldn't bolt onto our own cars.

Frequently asked questions

What are the best mods for an Mk4 Golf?

The best starting mods are a remap, a cold-air induction kit, and a coilover suspension setup. These three upgrades transform how the car drives and give you a solid foundation for further Mk4 Golf tuning.

Are VW Golf Mk4 parts still easy to find?

VW Golf Mk4 parts are widely available. We carry over 670 products for this platform from trusted performance brands, all in stock and ready to ship from our UK warehouse.

Is the Mk4 Golf 1.8T good for tuning?

The 1.8T is one of the most tunable engines in the VAG range. A remap alone can deliver significant gains, and the platform responds well to hardware upgrades such as larger intercoolers and exhaust systems.

What are Mk4 Golf coilovers for?

Coilovers are adjustable suspension kits that let you lower your Mk4 Golf and fine-tune the ride. They improve handling and give you control over ride height, making them one of the most popular Mk4 Golf mods.

Is it worth fitting a big brake kit to an Mk4 Golf?

A big brake kit is worth fitting if you're increasing power or driving on track. Larger discs and upgraded callipers provide shorter stopping distances and better heat management under hard use.
