The KTR-3RS is a direct-fit seat subframe for the Renault Megane 3 RS built between 2009 and 2016, covering the RS250, the RS265 and the RS275. It bolts to the factory seat fixing points in the floor, replacing the standard seat and runners with a solid base for a bucket seat or recliner.
KTR Racing makes the subframe from laser-cut high-grade steel and powder coats it black. That finish holds up in a car used on track, where the floor trim often comes out and the metalwork is more exposed. The frame sits low in the car; your final seat height depends on which side mounts you run between the subframe and the seat, so it is worth choosing those at the same time. Runners can be fitted between the subframe and the side mounts if you want fore and aft adjustment, though most track buyers run without them to keep the seat fixed.
The seat-side bolt centres sit at 345mm wide, the Sparco fitting equipment width. That is not the 405mm Recaro pattern, so check your side mounts match before ordering. KTR Racing note that some seats may need minor modification to fit depending on the seat size and make, and they cannot guarantee a straight bolt-in with every brand. If you want confirmation that your seat works with this subframe, send us the details and we will check.
One thing to confirm before ordering: the 3RS and 2RS subframes look nearly identical but the floor geometry changed between Megane generations, and they are not interchangeable. This part is for 2009 onwards. If your car is an RS225, RS230 or R26 from the 2004 to 2009 period, the KTR-2RS is the right frame for your car.
