XYZ Racing Street Advanced Coilovers — BMW 1 SERIES F40 3/4 CYL (Modified Rear Integrated) 2019-2026

The F40 1 Series moved BMW’s smallest hatch onto a front-drive-based UKL platform, and that shift changes what the rear axle needs from a coilover. With the modified rear integrated into this Street Advanced kit, the rear end is set up to work with the F40’s structure rather than fight it, giving 3/4-cylinder cars a suspension upgrade that respects how this generation actually sits and moves rather than treating it like the older rear-drive 1 Series.

This is XYZ Racing’s most fitted kit across the range, built for owners who want their F40 lowered and sharpened for road use with the option to run it on track days without a second setup. It suits a driver who wants a noticeably tighter car every day, then wants to wind the damping up before a circuit session rather than swap parts.

What this coilover does for your 2019-2026 Bmw 1 Series

Fitted to a 2019-2026 F40, this kit lowers the centre of gravity and firms up body control through the corners the UKL chassis is prone to lean into under quick direction changes. The 720-way damping adjustment is the headline feature here: it’s a wide enough range that you can run a genuinely soft, comfortable setting for the daily commute and then click through to a firm, controlled setting for a spirited B-road drive or a track day, without the compromise of a single fixed valving. Ride height is adjustable independently of that damping curve, so you can drop the F40’s stance without giving up the last of the adjustment range at either end. For the 3/4-cylinder cars in this fitment, that combination of adjustable height and adjustable damping means the front end turns in with less roll and the rear stays settled under trail-braking, which is where the standard UKL setup tends to feel vague.

About the Street Advanced coilover

Street Advanced sits at the centre of XYZ Racing’s coilover line-up and is the product the brand has developed longest, refined across years of use in competition by teams racing worldwide before that knowledge fed back into the road-going version. The defining spec is the 720-way damping adjustment, giving a far finer resolution of compression and rebound tuning than a basic 2-way or 4-way unit, so small changes in feel are actually achievable rather than jumping between two extremes. It’s built as a dual-purpose kit rather than a track-only unit, aimed squarely at drivers who use their car on the road but want the option to run harder settings on a circuit without buying a second set of dampers. XYZ Racing positions this as essential kit for anyone chasing genuine speed with control, not just a lowered stance, and the adjustment range is what lets one kit cover both the commute and the track day.

This kit is built for the F40-chassis BMW 1 Series, covering 3-cylinder and 4-cylinder derivatives from 2019 through to 2026, with the rear modified to integrate properly with the F40’s rear structure. Confirm your car falls within this chassis code and engine-cylinder range before ordering, as the rear-integration spec is specific to this platform.
