Carbon clams are hideous money compared to the weight saved, and dont save much at all unless they are auto claved or vacuum formed. Benetec CF Front Clam 4,95kg Vs std at 15kg but 58k:(
Be very wary of poly side screens. They are very flexible and with the roof fitted flare out dramatically at speeds above 60MPH.
Early rear arch liners are 2.8kg. Later liners are lighter.
Removing the GRP where the reversing light and fog lights are, along with the grilles and the reversing light saves about 1kg.
The rubber seals around all four wheel arch liners (assuming you haven't ditched the arch liners) are about 200g each, and most of the boot lid seal can be removed with just token parts left in to prevent rattle giving about 1kg of saving.
Exhaust Exige/111R Catback: 13kg. Stage 1 11.8Kg(saves 1.2KG), Stage 2 8,2Kg(saves 4.8KG), , Quicksilver Titanium 5,2KG(saves 7,8KG)
