Have you weighed your Caterham?
Discussion
My Superlight R has been weighed a few times as part of the sprint series I compete in (superlapscotland). Last time it weighed in at 535kg with half a tank of fuel using digital corner weighting scales. I would love to get it sub 500 I cant see how it can be done. Apart from a k-series R500 with all the extra magnesium parts I cant see many caterhams being sub 500kg.
My spec when weighed was:
Superlight R bodywork i.e. carbon nosecone, front and back wings and dash
Oddyssey battery - 5.1kg
single diagonal roll bar + petty strut
1.8k series, caterham dry sump tank - 6 speed gearbox
no windscreen wiper motor, no hood sticks
half a tunneau over passenger side, vinyl half door
both tillets in the car (drivers side on rails)
powerspeed 4-2-1 exhaust with integral cat (a bit heavier tan my ex-raceco exhaust)
radtec aluminium radiator

I had one of these before and it came in at around 520kg with maybe 3/8ths of a tank of fuel... Single Tillett seat mind you. cage and screen as per carphotographer's.
The Ital axle was a fair bit lighter than the De-Dion, I don't know how the live axle in the 160 compares in that respect...

Fair point, maybe later chassis are heavier too?

My 200 R400K Superlight weighs 542kg according to PGM's scales with all liquids at the correct level and 1/2 tank of fuel.
My 1998 1,6K Supersport weighed 633kg with me in it and half tank of fuel (so probably around 533kg without me as I was dressed for the cold 
)This is with no rear wheel or mount, no hood but hoodsticks and half hood, standard doors, 14" minilites, heater, standard battery plus a small tool kit
