GT40 Upgrade

[marksy40]

I am looking to do some upgrading of the GT40 as the car is now 12 years old and getting a bit rough in places. Long term I will do a motor upgrade, respray and interior change but for the moment I will start with some smaller items.
Firstly, the side mirrors on the car (see attached photo) are cheap and easily moved if bumped. I was thinking of replacing them with bullet mirrors but does anyone have a better suggestion? I would like the high mount electric style I see on some cars by they are a fairly expensive and i'm a little worried the bullet mirrors will not sit out far enough to get a decent rear view. So I'm open to suggestions.
Secondly, I want to replace the current seats with some fixed back racing seats such as SAAS, Recaro or similar. The width of the new seats would need to be 520mm maximum or they won't fit the space and I would need a low sitting position. The original seats are the fibreglass ones supplied by DRB in 2000. Does anyone have a suggestion of which seat is best or have some for sale? Condition is not a problem as I would get them reupholstered when we redo the interior.
Just waiting for the bank balance to climb a little before embarking on the other improvements. I will start a new thread once I kick off the major work.
