Product Details
The Studio RSR bolt-in roll bar for the 2017-2021 BMW M240i stiffens your chassis where it matters most, giving you sharper, more confident handling on track and a serious step up in occupant protection for HPDE, time attack, and weekend racing. It is engineered specifically for the M240i, so it follows the lines of the interior and bolts to the car's factory mounting points for a tight, purpose-built fit.
Designed and built in-house in the USA, every M240i four-point structure uses wide-radius mandrel bends and CNC-machined interlocking clamps for a clean, race-grade look and a precise, repeatable install. Because it is rear-seat compatible, you can keep a street-friendly interior and still run the car on track. Choose DOM mild steel or lightweight 4130 chromoly, powdercoated to order.

Installation
This is a true bolt-in structure that mounts to the M240i's factory hard points — no welding, no drilling, and no cutting of the chassis. The interlocking tubing clamps let the bar go together inside the car and come apart again if needed, and all Grade-8 hardware plus step-by-step instructions are included. Professional installation is recommended.
