Yes Martin it does require some more leg power! but decided after discussing the merits with Brian who in turn spoke to Sean Hyland,and that whilst the engine was out no harm would be done in fitting a stronger clutch,one thing I was pushing hard for was a lightened flywheel but Mr Hyland advised against this strongly particulary in a "daily drive car", ok for the track and big power applications but could be unsuitable for town driving....or something along those lines,and as that advice doesn't come much bigger had to concede the flywheel option!.
