The incredible Lightweight Bucket Seats from Porsche adorn many vehicles from the 918 to the GT3, GT2, GT4, T and many other models if so equipped. Also fits the 997 generation bucket seats. We created this adjustable lumbar support for our vehicles out of necessity. Not only for our backs, but the wives or significant other that agreed to that 6 hour journey as our co-pilot. Typically these are quite comfortable seats but on longer journeys, a little lumbar support goes a long way to comfort your back and your co-pilot’s back!! These install in a minute for each side, adjustable for height (lower back, small of back, etc.).

NOTE: Install at least 8” above the lower seat pad for maximum effect.

The air bladder is adjustable via a simple and lightweight ball pump. Once the desired support is obtained, the ball pump can be removed and tuck the hose and check valve into the seat for an invisible install. Or keep the ball for adjustment any time!
