Made by Recaro, a trusted brand that is known for producing high-quality car parts. Recaro SR series, SR2, SR3, SR4, SR5 (not for SR6+)
I had this on a SR2. Used for a short period of time before getting specific rails for my car.
Rolls forward and backwards smoothly.
You can probably cut the universal mounts and weld on your oem mounting brackets for a custom fit for your car (if you can't find a proper aftermarket seat rail for your own car's application).
Any questions please ask
