Has anyone made a serious attempt to reduce the weight of the coop? Mines off the road now for 6 months so plenty of time to play about with it.
I've searched the forum but not found much on weight reduction so any pointers would be great.
It is a heavy old lump for it's size!
Cheers Guys and Girls

At this year's Ten of the Best, I stripped out the following:
Front seats (replaced with kevlar race seats) rear seats door cards all speakers and headunit and CD player all seatbelts A, B and C pillar covers rear parcel shelf cover carpets and soundproofing beneath centre console and gearlever surround all boot lining spare wheel, jack & tools rear wiper and motor
I reckon it added up to about 100 - 120kg
However, it also added up to one of the worst headaches I've had in years - the noise was unbearable for anything above 20 miles (which was a bit of a problem, as Elvington was 120 miles away). I really should have used earplugs.
If you had a lot of commitment and deep pockets, I reckon you could get another 100kg off the car, by using carbon fibre for the bonnet, doors and bootlid. If you were *seriously* well off, you could probably replace the roof panel and rear three quarters with carbon as well - another 50kg maybe?
However, you'd still end up with a car over 1000kg AND it would be hateful to drive.
If you want a lightweight racer, start with a lightweight car. Why do you think the fastest FWD cars at TOTB were tiny (Corsa, Nova, Tigra, CRX)

I reckon I could loose 10kg by going on a diet. It all adds up.

You don't want to be riding on a full tank either. (or an empty one) so you can put in plastic balls to reduce the volume.

Do the smaller batteries provide the same oomph/power as the normal ones (sorry for the non-tech term!), for a normal car with A/C etc? If so it seems like a logical move to take some weight out from between the front wheels. Sorry for the hijack! FYI - have been using the 7 Kilo deka 16 battery for a while now and haven't had a problem starting due to lack of charge (but haven't got through winter yet) n.b. these are annoyingly expensive

punch in project lightweight and you'll see where I'm at the moment. I will be replacing my clutch in the near future so I'll be able to fit a lightweight flywheel at the same time!!.... On the 20v turbo the biggest problem isn't the overall weight (although it is too heavy) but the weight balance, the front is obviously heanier than the rear and the front right on rhd cars is approximately 15% heavier than the left... I was going to move the battery to the boot but until I can sort the left right imbalance that'll have to wait. My next project is to remove the sunroof and replace with std panel... Another 20kg's gone.... Yeah!!!
Cheers Tim

Update - the battery drained once due to lights left on and (despite the ad saying it handles deep discharge) hasn't been the same since - certainly won't hold charge for > 14 days. To help out got a solar charger from maplins 'cos I don't want to be stuck in the arse-end of woolwich waiting for a jumpstart again!
