XYZ Racing Street Advanced Coilovers — BMW 4 SERIES F33 4/6 CYL (excl. M-Technik. xDrive & EDC) 2013-2026

The F33 Convertible carries more kerb weight and less torsional stiffness than the F32 coupe it’s built alongside, a trade-off of the folding hard-top roof and the extra scuttle bracing BMW added to hold the body together with the tin roof gone. XYZ Racing’s Street Advance coilover is built around that reality rather than against it, giving the non-M-Technik, non-xDrive, non-EDC 4 Series range – both 4-cylinder and 6-cylinder cars – a chassis that resists the extra flex without turning the ride brittle on a UK B-road.

This is a street-first kit with genuine track-day range built in. Because these cars left the factory without adaptive dampers, the swap is straightforward: passive coilover in, no fighting the car’s EDC electronics, no reprogramming required. That makes it the natural upgrade path for a rear-wheel-drive F33 owner who wants a firmer, better-controlled car for daily driving and the odd circuit outing without inheriting the complexity of an electronic damping system that was never fitted in the first place.

What this coilover does for your 2013-2026 BMW 4 Series

Full height adjustment drops the F33’s centre of gravity, working directly against the extra mass the convertible carries over the saloon and coupe. The independently adjustable damping lets you firm up the rear to control body roll through direction changes – useful on a chassis that already has more structure to manage than the coupe – while keeping enough compliance for motorway and B-road use. Because the range covers both 4-cylinder and 6-cylinder cars, spring rates are matched to the different weight over the front axle rather than a single generic rate. The result is a 4 Series that turns in with less lean and settles faster after a compression, without the factory car’s softer, weight-compensating tune.

About the Street Advanced coilover

Street Advance is XYZ Racing’s highest-volume coilover line, developed over successive seasons and proven in international racing before being tuned back for road use. It’s built for drivers who split their time between normal road driving and track days rather than committing to one or the other, with 720 individual damping positions giving a genuinely usable range between comfort and control instead of a handful of coarse steps. Construction follows XYZ’s standard road-and-track platform: adjustable ride height, a damper tune that holds its settings under repeated use, and a spec aimed squarely at drivers who want both pace and predictability from the same car.
