if you want a lighter bonnet gut some of the structural bars out, its not as if your going to be lifting the bonnet to check the engine often is it?
thats exactly what i was trying to say though.
you remove all of the stuff that you dont need first, because that stuff is free to remove, just takes a bit of hard graft the remove sound deadening, etc.
next you cut out metal where you can afford to lose it
(as youve said).
but after that you cant lose any more weight, because everything left is required.
so you have no choice but to replace with items made from lighter material.
if youve already gutted the car and cut away metal, and you STILL want to lose more weight, then chances are you have a fairly serious car in your hands
(race car, hardcore track car, or youre just rich and want to go beyond the necessary for your project car) and thus spending
£300 to lose 7kg isnt such a major issue
personally i wouldnt bother with composite wings as the metal is fairly thin and doesnt weigh that much.
the bonnet weighs 15kg and you can get that down under 5kg with composites
(maybe even less with carbon fibre), t-bar glass probably weighs 6-10kg and you can get that down under 2kg easily, if you were to replace the t-bar entirely with bolted/rivetted in plates then you could probably lose 10-15kg there as well
for a bonnet and some t-bar glass alternative you are probably talking about
£400 or so.
add another
£200 for polycarb rear and quarter windows and youve shifted 30kg or so for
£600.
not breaking the bank, and making significant savings.
30kg off of the 900-950kg the car would weigh properly gutted is about 3%
