Could start off with the heater kit and plates behind seat heads, and perhaps the rear shelving/firewall cover and insulation, I reckon those together are pushing 15kg, maybe a bit under. Im a bit out of knowledge on this part tho, try messaging forum member 'Nev', he's got some good knowledge around this area, but I'm sure lots of others have too :)

already removed any interior bits we dont need,and plan to remove all heater parts and poss rear screen winstars post above mentions the undertrays,has anyone run without them?? i am thinking that if the car was fitted witha functioning splitter and some side skirts it would create negative pressure under the car and thus draw air thru the engine bay reducing heat??

Has anyone worked out what difference the weight saving will make to the performance? For example: Each saving of 10kg will result in a 0 - 60mph saving of ....seconds?

Get a hair cut and leave your wallet in the van, theres a big weight saving. Then look at pro alloy fuel tank. Remove headlights and fit blanking plates remove dashboard, perspex windows/no windows? Remove alarm and locks.

Its a turbo so already has a plastic cover. He already has a lightened flywheel fitted. The wheels are worth considering although expensive as he runs heavy speedlines at the mo

Elise Parts aluminium centered disc brakes would probably save a bit too, and saving weight off bits that go up and down and round and round is worth more than normal weight saving.
