So any update on these? Pricing? Weight vs stock 915?

Thank you,

Thank you,
price is 2.690 Euro incl. 19 % VAT.
Have to check weight when next batch is machined. Haven´t done yet and have no sample on stock (only casted raw cases). Will be a little more than OEM.

Thanks for the links, do you think these could handle 400+ RWHP?

Are these built with internal clearances for use in 914 cars?

We just started milling a new batch of some cases. There were minor changes to the mold. Will post some pictures as soon as I can.
For 914 or in this case 916 usage the clearance for the flipped differential has to be made as on an OEM case. The thread for the little bracket for guidance of the shift actuator shaft is always cut. So, much more precise than doing it with a pattern/template.
Will take some days to have them finnished, but will keep you posted.

The new batch of gearbox cases is just in final production on a 5-axis CNC Mill. Hope to have them back next weekend.
Cases can already be reserved/ordered through our shop www.bott-parts.de.

Pictures, when they are done!
