These no compromise 964/993 front uprights from BBi Autosport are more than just another billet copy of the RS uprights. The roll center has been corrected and bump steer has been virtually eliminated. The shock mount was also lowered by 50mm, accommodating lowered vehicles and gaining back shock travel and correcting suspension geometry. Fully compatible with OE heat shielding, sensors and bearings. The caliper mounts are designed for the OEM Porsche 993 Brembo units.
The whole upright is not just optimized for suspension geometry but for strength and weight. To ensure best performance on track, the part was subject to extensive FEA testing to be 2x stronger than the OE part. Structural ribbing has been added to increase rigidity. It has also been optimized for weight. Each upright is just 5.56lbs despite the added strength and denser material.
Fitment Note: 964 Require Updated inner and outer tie rods. 993 requires RS outer tie rods. RS style inner tie rods, outer tie rods, and new wheel bearings can be added above.
993 Brakes or equivalent big brake kits (for 993) are required.
