Changed the battery from a standard Sierra to a motorbike one.
Best bit was the battery was a £1 ebay special and the acid cost me £2!

Ive fitted light weight alloys. ATS DTC's (optional extra on some Westies).
Removed dizzy. Swapped carbs (not sure if i saved weight or not but it goes better). Not fitted header tank.

You also added weight with all that girly padded trim on the seats and the tunnel etc

wheels and tyres , lighter calipers, solid discs instead of vented alloy bolts in none stressed areas other bolts cut to length, grp seats instead of
padded type and not taking a pasenger aswell
A pint for the gent and a white wine/fruit based drink for the lady. Those are the rules

Alloy bell housing, small alternator, alloy diff housing if you're using english axle, alloy hub carriers, single digidash unit compared to
multi dials, alloy dampers with smaller diam. using smaller diam springs, alloy front uprights, alloy fual tank (smaller?), alloy T9 gearbox case
(quaife) light CDS tube roll bar etc... there's a lot you can do, but most if not all cost a bundle.

if you don't take a passenger, why do they need a seat?

PS - Perforated chassis and floor, bolts cut down to size, helium in tyres...

You could fit smaller resevoirs (wrong spelling i think) for water, coolant etc
How long can i resist the temptation to drop a V8 in?

alumnium radiator, mount close to engine to keep hoses short, helium in tyres, spoked steering wheel, don't paint bodywork, don't fit
windscreen, fit LED lamps so can use thinner section cable, no reverse lamp or wiring, ... and so on.

you have all missed the obvious one.. (unless I missed it!)
Go on a diet! Undoubtedly heaviest and most useless part of most cars is the driver... shed some weight there! (I reckon I could/should save about
30lbs )![](/images//smilies/tongue.gif)

without going into the obvious the guy i bought my car was a weight saving fanatic and im going further with more carbon /titainium and ally
bolts.change steering column to tube with your connectors rewelded,lightened discs to rear as well as front,ally pedals instead of steel or drill
existing,lighten lobros even heard of gun drilling drive shaftsand centres of bolts.drill holes in anything which isnt stressed .stick on tax disc
holder the list ,goes on

Hehe - Somebody had to say it!! Saves at least 80kg anyway.
Alloy dampers can save a chunk of weight and quality dampers are a good upgrade anyway.

Drilling driveshafts? That is quite extreme. I wonder what the theoretical lowest weight could be, if you followed all of the above suggestions... If
you were starting a build and had the option (and money) to fit all of the lightest parts available, a BEC, CDS tube, titanium fasteners, CF instead
of GRP etc etc. what do you think the lowest ROAD LEGAL car could be - I would hazard a wet weight (with a tiny plastic fuel tank!) of 350kg. Then you
could look at going very silly and make the chassis from carbon (yes it can be done and I've seen it - it was very light and very stiff, but you
add the need for earth wire everywhere)... sod it, lets just walk and be done with it.

Bike battery is probably a better bet

Lighter wheels are often the most noticable upgrade. You lose a few pounds with lighter rims/tires, you are losing unsprung mass, and you are losing
rotating mass as well. Rotating mass reduces power so its three for the price of one . More power, less unsprung mass, and less mass overall.
Cheers.
