Update!
Just talked to Betim. They have prototypes, and have completed bump and geometry analysis of the stock parts, along with the stress and materials analysis. However these are not 100% copies of the factory parts, the geometry is vastly improved over the factory's part. They designed them to work from 964 RS height and down to our BBI club racer height (aka) slammed. The camber and toe curves are as good as the front of a factory 997.2 cup car. The billet component is 2 times more rigid as well. Will reduce pad knock back due to casting flex.
Final sellable parts are about 8 weeks out. BBI will be accepting pre-orders.
Retail will be AROUND $2900.00 US for the pair (final pricing is TBD) and will include the RS style solid inner tie rod and a solid monoball outer tie rod with bump steer adjustment.
I have the factory parts on my car and these are being put on it along with some additional work Im doing to my 964.

and these are radial mount? will accept big red without adapters right?
what rotors do we use? 993 turbo rotors or 965 rotors? since the offset is different between the two. Thx
for those who wants to keep stock 964 calipers. what are their options?

They are 993 parts so you use 993 brakes and rotors or equivalent aftermarked. I have brembo bbk on mine. Accepts 993 braking systems.
I have factory 993 rs evo gt2 whatever they are called and these will allow for bump correction without shims and better geometry swing.

Very nice...
Although I recently purchased what may have been the only new set of the 993RS hubs on earth...lol, these are tempting as hell.
I imagine the decrease in weight will be considerable.

i seem to remember its about 5 lbs ... so 10 lbs in total x4 (theoretical adjustment for unsprung weight)
=40lbs .. not easy amount to find in a stripped car

Very nice design ,
the arm where the outer tie rod bolts on those is completly different than on the 993 RS upright, did you mention they review and improve the geometry ?
Can those be used with the ERP outer tie rods ?
I imagine with different spacers provide in the original ERP kit.

Yes. Bbi uses ERP for all suspension control arms. I believe no more spacers needed however.

I'm sure he would you will need 993 style rods though.

Bbi will be taking pre orders shortly for the first run.

A few pics from 3D printed prototype. A few changes from this will be in the real version.
Will post camber and toe curves for stock, rs, and these soon.
