pondering the benefits of a 6 speed gearbox conversion.

Stock power you should be ok, just keep up with oil changes and don't be overly aggressive with it and it will be fine.

Ok useful to know thank you the advice about double clutch and rev matching I presume stands.

I was planning on building this into a track car ideally at Clubman level initially so have been focussing on handling and breaking. I imagine this gearbox may get used quite hard at some point. Should I be considering getting a 5speed?
