Adapters made in CNC technology, which gives a high quality finish and 100% fit to the car. The material from which they were made is durable 7075 PA9 aluminum. They have M8 threaded holes that allow you to adjust the perfect position behind the wheel to each seat. Adapters will fit almost any sports or racing seat with side mounts. Universal mountings for bucket seats are also required for assembly. The platform does not significantly increase the height on which the seat is mounted, thanks to which the adjustment range remains very large. They ensure a properly centered and comfortable position behind the wheel. The mounts are sold sides, left (driver) or right (passenger). The kit for one side (left or right) includes: inner mount (left or right) outer mount (left or right) Hey there!Please verify with us on stock levels prior to ordering this item if this is needed urgently, as not all of these items are in stock with us currently and may hold a 3-4 week ETA before shipping!Thank you for your understanding and patience!”
