A Boxster/Cayman/911 transmission has two separate inputs for shifting on the exterior of the transmission. It was designed for cables from the get-go.
Subaru has a conventional shift rod like VW and Porsche USED to.
Anyway, THIS thread is about Joel's Boxster-powered Beck coupe. Subaru talk is well, unnecessary thread drift.
If you want to talk about Subaru shift setups, start your own thread.
