FAQ
What R-908X bracket do I need? The specific R-908X model depends on your Porsche platform and seat type. Consult the Brey Krause side mount adapter guide to match brackets to your car.
Can I use this on other Porsche seat types? This mount is engineered for GT3 seats with R-908X brackets. Using it with factory or aftermarket seats without the matching brackets will not yield proper geometry.
