Thank you for your understanding, String Theory Garage Team
Bilstein B12 Suspension Kit — Porsche 997 Carrera 2
The Bilstein B12 is the definitive OEM+ suspension upgrade for the Porsche 997 Carrera 2 — a complete kit combining Bilstein B8 monotube dampers with Eibach Pro springs, delivering a meaningfully improved driving experience without sacrificing the everyday usability of the car.
Where budget coilover kits offer adjustability at the expense of quality, the Bilstein B12 kit does the opposite: it uses proven, premium components matched and tested together, offering a plug-and-play performance upgrade that dramatically outperforms the standard suspension in body control, ride quality and driver confidence.

Bilstein B8 monotube performance dampers — front and rear (4 units)
Eibach Pro lowering springs — matched to B8 damper rates

No adjustment needed — the kit is pre-calibrated for road and occasional track use
