I was going to suggest putting the driver on a diet. I recon I could get 200kg out of a full spec rangie and have it stay street legal but then youd also be compromising drive line integrity as id be pinching some weight from there.

This also depends on just how friendly your local roadworthy place is....

Replace the floor and panels with cardboard.

I've actually lost a lot of weight since I last saw you, then I found it again when I got a new job and am travelling 5hrs a day. We can't all be skinny, even though I once was.

It's a bit funny having this hread and Dave's fifteen tonne Bushmaster thread running at the same time.

What's the aim? Are you planning on building a rally car?

Why not go the whole Tomcat/ Nascar type line with a custom space-frame chassis and polycarbonate panels?

Were you a used car dealer?

let me guess, you lost the dog and found it again on a trip to work?

Oh the humanity as the RRC hits the tie down tower and bursts into flames.
Did anyone else ever think Victor Bray could stop stressing so much about carbon fibre if he laid off the cheeseburgers?

**Slunnie** · 4th August 2007, 10:32 PM

Yeah. It must have been hard for him knowing that it didn't matter how well he built his cars, they were always good enough for another .5sec and 30km/h.

Some people eat when they get stressed.

We removed a lot of weight from a 1981 RR for the '92 aust safari in order to increase the power to weight ratio. We wanted a standard and therefore reliable engine, so we went for a high comp 3.5 (EX 110,) and a 727 Torqueflyte auto with a 1.22:1 Lt230. We removed all the sound deadening, the roof lining, the bonnet was fibreglass, the rear tailgate was 1 piece f'glass, no side windows, lightweight exhaust, standard rear and front bumpers, kevlar seats weighing 3kg each, and removed a few other extra bits of wiring and switchgear etc. It is amazing how much all these little bits add up, as when the vehicle was weighed pre event, including FISA spec rollcage and safety gear, it weighed in at 1601kg.
We carried minimal spares, and no highlift jack, only a bull bag.
This vehicle was quite spritely for an auto, the lower high range gearing and a revvy 3.5 was more than capable for the task
We broke nothing, we came 2nd in National class and times overall were about 12th outright.
Whats more, we drove from Perth to Sydney, competed to Darwin and then drove back to Perth afterwards, with no support vehicle.

The best thing to do with any 4x4 is to reduce the weight.
This will INCREASE the power to weight ratio WITHOUT spending $$$ on the engine etc.

AND you'll use less fuel.

Do It.
