Getting slight clutch slip so going to get it all changed, but wondering as eventually it will be running 400-450 bhp is the standard clutch capable of taking that easily enough?

Interesting question, my 35i manual is on 125k miles and is around the 380bhp range, I’ve no idea when the clutch was changed, but it must have been, not that I do them often but it’ll happily do standing starts at 5k revs in the dry with zero slip, so I’d presume 400bhp wouldn’t be too much of an issue.
