Probably not cheap, but avaivable for the 915 box and maybe even the G31. Ideal for the 2nd and 3rd shiftplane.

"Hi a quick update on the dog box.


It is now working well and we will use it in the first rally next month.


Let me know how i can help you further.


Kind regards
Richard

If they are directional they will not work in the G31. The G31 shafts spin in opposite directions from the 915. This is why you cannot use all 930 dog teeth on the G31--only the symmetrical ones. The asymmetrical ones have the angle of the teeth on the wrong side.

Thank you for enquiring about our 915 5 speed dog gearbox. I am pleased to say that 4 have been made, tested and used in competition and we are now looking at the first run of production.


The results are extremely encouraging and the performance advantage is amazing - it transforms the car!!


In the current form we are happy to supply as complete gearboxes, ready to use with LSD fitted. The cost for a complete unit will be £15,220.00 and i am looking to discover the level of interest from the numerous enquires we have had.


I would appreciate your feedback on this news.


Kind regards
Richard
