XYZ Racing Pro Rally Coilovers — BMW 4 SERIES G26 (2WD/4WD) 4/6CYL (Modified Rear Integrated) 2020-2026

The G26 4 Series Gran Coupe was never drawn with a gravel stage in mind, which is exactly why the "Modified Rr Integrated" designation on this XYZ Racing Pro Rally coilover matters more than any number on a spec sheet. This fitment is not a bolt-in replacement for the factory rear geometry – it is built for a G26 whose rear end has already been structurally reworked to take a rally-grade mounting point, one capable of surviving repeated compression events at speed on loose or frozen surfaces.

That distinction is the whole story for a 2wd or 4wd, 4- or 6-cylinder G26 heading into top-flight rally competition. A car this size and weight, running on gravel or snow instead of tarmac, needs a coilover that treats the rear subframe as a load path rather than an afterthought – and that’s what a professional-integration kit like this one is engineered to do.

What this coilover does for your 2020-2026 Bmw 4 Series

On a rally stage, the G26’s mass shows up first at the rear axle under compression – over crests, through compressions, and on the landings after jumps most road-going 4 Series owners will never see. A coilover built around a modified, integrated rear mount spreads that load into a structure designed to take it, instead of stressing the original unibody pickup points the way a direct-fit amateur kit would. Ride height becomes a competition variable rather than a cosmetic one: raise it for rutted gravel and deep snow clearance, drop it back down for smoother, faster stages where a lower centre of gravity pays off in transition speed. The result on the 4 Series is a rear end that stays composed through repeated hard hits instead of degrading a stage or two into a run, which is the difference between finishing a rally and retiring from one.

About the Pro Rally coilover

XYZ Racing splits its gravel and snow rally suspension into two distinct approaches. The first bolts directly to the original chassis – an amateur-level setup for cars kept close to standard. The second, which this kit belongs to, is designed to go in only after the car’s body has been modified specifically to accept it, giving the coilover a professional-grade mounting interface rather than a compromise built around road-car hard points. That’s the "Modified Rr Integrated" designation in the product name: it’s not a trim label, it’s a build requirement. The Pro Rally line exists for exactly this scenario – a 4 Series taken beyond road-car spec and prepared as a genuine competition car, where the suspension needs to match the level of chassis work already done to the rear end.

Fitment for the Bmw 4 Series G26 (2020-2026)

This kit fits the G26-generation 4 Series, chassis code BM122-1, across both 2wd and 4wd drivetrains and 4- and 6-cylinder engine variants, covering the 2020 to 2026 production run. It is specifically for cars with the modified, integrated rear mounting already in place – confirm your car’s rear-end preparation matches this fitment before ordering rather than the standard, unmodified chassis.
