Thank you everyone for all the patience for our highly anticipated BBi StreetCup Porsche 964/993 Billet Uprights. We have been working hard on the development of this product for the last 3 month and here is the final prototype after we spent over 200 hours of design time and went through 4 revisions. Engineered for more strength and adjustability than the factory EVO/RS piece, they will be 5 axis machined from billet 6061 aluminum with revised geometry for full bump steer adjustability and improved camber and toe curves for lower than RS ride height.

"Huge Difference - turn-in is much more immediate, no more on-center wiggle/sloppiness, the weight through the wheel loads up in a nice way now, and that bump steer is no more! The wheel carriers were installed with the tie rods and ball joints from you guys as well. Amazing package!" - Francis

Fitment Note: 964 Require Updated inner and outer tie rods. We strongly recommend upgrading the lower ball joint as well.

993 Brakes or equivalent big brake kits (for 993) are required.
