BMW 1 Series (F20) with Coilover Suspension

The BMW 1 Series (F20), a compact premium five-door hatchback, boasts a sporty DNA with a perfectly balanced weight distribution and a classic rear-wheel-drive layout – a rarity in this vehicle segment. Manufactured from 2011 to 2019, it offers a broad range of powertrains, from efficient four-cylinder engines to the powerful M135i with 326 hp. To fully unlock its potential, a height-adjustable performance suspension is the ideal upgrade. Thanks to its continuously adjustable lowering range, the ride height can be fine-tuned for sharper handling, improved stability, and a significantly more aggressive stance. Compared to a traditional sport suspension, coilover systems stand out through their flexibility: lowering is adjustable to your exact preferences, offering both visual and dynamic advantages. While a sport suspension typically lowers the vehicle by a fixed amount of around 30 mm, coilovers often allow adjustment ranges between 35 and 65 mm – ideal for a personalized performance setup. Especially in the BMW 1 Series F20, this results not only in a sportier appearance but also in more precise steering response and a more direct on-road feel.
