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 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.

A Complete Suspension Transformation
Inspired by Porches own factory race program, the complete BBi GT3 Suspension Package replaces all moving linkage points to the front and rear wheel assemblies. All factory rubber bushings are replaced with high strength steel-alloy spherical mono-balls removing all flex and deflection. This maintains perfect wheel alignment in all road and race conditions inspiring confidence when pressed to the limits of adhesion.
