Lightening suspension components

[Mr Classic]

Starting my mini build from the bottom up, and was looking to lose a few pounds along the way (both £ and lbs. )

So, best ways of lowering unsprung weight firstly? Currently thinking alloy carriers and hubs at the front, possibly disk brake conversion at the rear. Also notices the weight of some of the other bits approx 10kg per trailing arm and driveshaft and complete brake set being around 15kg each side! So any options which would reduce the weight without spending a ridiculous amount, I do appreciate rear disk brake conversions can come in around £650...

Now I'm sat here smiling to myself... I'll start work on fixing rust on the shell first, then see what I can do. ATM it is literally a pile of parts where i bought it, seems I have two steering racks, two steering columns, and two driveshafts with the wrong splines?? Very confusing. Thanks for the help!

£70 for reducing the weight from 4.3kg to 0.2kg, plus you can sell the old one for around 20-30 quid if its rust free. No brainer me thinks!

Probably going to go for a fair few carbon fibre/fibreglass replacements, my list so far is:
Boot lid,
Wings/bonnet (one or two piece)
New doors if possible, that'll save 40kg on its own! Maybe going for aluminium with perspex windows, wouldnt mind having winders still though.

No rear seats, 4 or 6 point cage with side bars if I have fibreglass doors, bucket seats in the front.
