BBi 911/991 GT3 Spring Upgrade Kit

Shock Not Included, Springs Install On Existing OEM Shock Assembly

Improve Handling Without Sacrificing Comfort

Sharpening the handling of your GT3 does not have to come with a free back ache. While the OEM GT3 springs are tuned for performance, their design provides an inherent draw back when pressed to the limits.


OEM GT3s use progressive springs with a variable spring rate. While this provides a soft ride, it also transmits more body roll into the chassis reducing confidence at the limits of grip. BBi's StreetCup Upgrade retains a modest spring rate specifically designed for OEM shocks, but use linear springs. Linear springs provide a very stable and predictable feel for both spirited driving or track conditions.


With the assistance of softer helper springs, drivers can experience the best of both worlds; daily comfort mixed with track focused responsiveness.
