The Bilstein B8 Performance Plus (DampTronic) front right strut, part number 35-348153, is a replacement damper unit for the Porsche 911 from the B8 sport-tuned line. Bilstein positions the B8 as a shorter-bodied shock built for lowered cars, and this Performance Plus version is designed to pair with lowering springs while keeping the car's electronic damping control in place. The DampTronic name points to electronic damping compatibility, so this strut is meant to sit alongside the factory adjustment system rather than replace it with a fixed-rate setup.
Compared with a generic aftermarket strut, the reason to choose this unit is that it was engineered around the 911's electronically controlled suspension and a lowered ride height, rather than a one-size-fits-all valving curve. The manufacturer lists fitment for the Porsche 911 from 2006 through 2013, and the product name specifies the Carrera 4S, so confirm your exact model, year, and whether your car has electronic suspension before ordering, using your VIN and the manufacturer's catalogue. Search terms owners use for this part include 997 Carrera 4S front strut replacement, DampTronic front strut 911, lowering spring compatible 911 strut, and Bilstein 35-348153. The manufacturer lists the unit at 18 lbs.
The manufacturer's fitment table lists the Porsche 911 for 2006 through 2013. Because the product name specifies the Carrera 4S and electronic suspension equipment affects which unit is correct, verify your VIN against the manufacturer's catalogue before ordering.
Yes. The manufacturer designs the Performance Plus line for lowered cars, and the B8 series is rated for lowering springs up to 50 mm.
The manufacturer states that B8 dampers fit like the standard part and do not require replacing the springs. Confirm the spring setup for your specific car before installation.
This is a front strut replacement, which is a moderately involved job that usually requires a spring compressor, a jack and stands, and standard hand tools. Work on one corner at a time so the opposite side remains as a reference. Keep the electronic suspension connector and wiring clean and undamaged, and have a professional wheel alignment performed once the strut is installed, since front strut changes affect camber and toe. Review the manufacturer's installation instructions for this part before starting.
