Product Details
The Studio RSR bolt-in roll bar for the 2008-2013 BMW M3 Convertible 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 M3 Convertible, 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 M3 Convertible four-point structure uses wide-radius mandrel bends and CNC-machined interlocking clamps for a clean, race-grade look and a precise, repeatable install. It installs without cutting or welding, so your interior stays clean and the bar can come back out if you ever sell the car. Choose DOM mild steel or lightweight 4130 chromoly, finished in your choice of powdercoat color at no extra cost.

Installation
This is a true bolt-in structure that mounts to the M3 Convertible'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.
