Bilstein 48-347747 is a B16 (PSS10) complete coilover suspension kit for the 2001-2005 Porsche 911 (996) Turbo and Turbo S. B16 is the top of Bilstein's street range and, unlike the B4, B6 and B8 damper lines, it is a full kit rather than a single damper: the monotube dampers and their matched linear main and tender springs are all supplied together, front and rear. Nothing else needs to be bought to change the car's spring and damper package.
Each damper carries a 10-stage click adjuster that moves rebound and compression together, so the whole car can be softened for road use or firmed up for track work without removing anything. The zinc-coated threaded bodies set ride height independently of the damping setting, allowing roughly 30 mm to 50 mm of lowering. Springs are linear rather than progressive: 257 lbs/in. main with a 114 lbs/in. tender at the front, 514 lbs/in. main with a 79 lbs/in. tender at the rear. The kit is made in Germany and covers one complete vehicle.
