Weight Savings For Xr6ts ?

Mk II 17" std wheels and tyres 25kg (my spare)

Allowing 9kg for the tyre (please correct this figure), say 16kg for the rim.

BBS 17x8 rims 16.4lbs!

OZ 17x8 rims 15.9lbs!

The downside is the BBS and OZ rims are AU$800+ retail per rim.

If you can do better than this for a correct size and offset lightweight 17" rim please let me know.

It would be interesting to have access to the weights of the XR6T and F6 factory rims, and factory rim-tyre combinations for 17", 18", 19" for the various styles.

It would also be interesting to know the weights of after market rims, and rim-tyre combinations, for popular brands such as Starcorp.

All you need is 10 minutes, a matching spare and a bathroom scale.

I have a set of Volk TE37's in 17" on my import which are light, will give them a go on the XR and see how they fit/look

take the engine out there made of metal....that'd be pretty heavy right?

Looks like the Volks are a good thing.

sounds like you took your brain out and forgot to put it back in..

Don't be so mean - he might have made a new one out of cardboard.

First place to save weight, I think, rims.

Look at getting a set of lightweight racing wheels. I had enkei RPO2s on my ute. 5kg a corner lighter than the stock rims. There's 20kgs. Your suspension will work better. Braking distances will improve. And ofcourse, acceleration.

Plus, you'll start to customize the look of your car.

The carbon fiber bonnets from AWC are said to be 15kg lighter than the stock bonnet from memory?

Remove the wing. Couple of kilos there. (for utes, remove hardcover/sports bar)

Lightweight racing seats.

Lightwheigt battery.

Remove spare tyre and jack. (Rely on roadside assist if you get a puncture)

All this would probably equal the weight of an average passenger? I definately notice the extra weight when I've got someone riding shotgun...

That's all I can think of before you start compromising the 'comfort' of your car. Start removing speakers, door trims, headliner, air con, rear seats you start to lose the day to day driveability, liveability, of the car.

Thanks glad I can get a few serious replies to my query

What were you thinking Summhommoner,

IT IS A FALCON, for furks sake

Did anyone do any follow-up research on this?

If someone could tell me the weigtht of the standard parts, that would be !

XT / XR6 Bonnet = kgs?

GT / XR8 bonnet = 30 kgs (is that right?)

-> should be able to get this to less than 5kgs using vacuum-bagged epoxy/carbon/kevlar with honeycomb or foam core. And be stiffer, stronger and crash proof.

Boot = ?

-> less than 3 kgs should be doable.

GT wing = ?

-> estimate larger wing with larger side-plates would be ~2 kgs

GT Front bar = ?

BTW what does a ute hardcover weigh?

Thanks for your info.

Cunner's weight saving tips:

1 - Cut the roof off.... great for those mild summer days.

2 - remove all windows and replace with glad wrap

3 - Strip all paint from vehicle

4- Remove exhaust altogether (who needs it anyway)

5- remove clunky steering wheel and replace with lightweight carbon doorknob.

6- Remove all accumulated dead bodies from boot and replace with helium ballons.

7- Don't wear clothes when driving.

Simple and effective

Thank me later....

Take the entire car appart, down to a rolling chassis.

Goto the local Material engineer (there is one next to most Coles/Woolies) and get him to forge up a hollow Aluminium alloy space frame to replace the steel chassis.

It will be roughly 40% lighter and about 20% stronger (so you've just increased the torsional stiffness also; read: Better handling).

Start putting the car back together. Use shorty carbon titanium locking bolts/nuts, instead of steel bolts, for all joints. They are 75% lighter (that's a big one). that's goto be like 100kg's right there..... They use them on spaceships (NASA sell them cheap if you buy in bulk).

Have the engine block, a silicon aluminium blend, pressure die cast around special titanium alloy cylinder liners (which have less friction (~10 - 30% less. Smaller atoms = tigher atomic pack (in HCP, to be specific) = smoother surface) for less wear, higher RPM limits and more power (obviously). Lighter rods and all that crap are boring, but you do that anyway... This saves 25% of the engine weight.

Moving along, you don't need that big flywheel to get the same effect. Get someone to make a lighter one, that carries 90% of its weight > 75% diameter. Change the gearbox to some boring magnesium (no titanium, boo) special. Keep all the same mechanical part dimensions, just replace all parts with stronger, lighter (so you need less, therefore it must be cheaper too!) carbon shot specials.... Do the same for driveshafts (Some strange thing, bil... billet? Yeah that's the one... I dunno, its boring cheap stuff, everyones got them)... All this makes the driveline around 25% lighter (you have to use a bit of steel still, so you don't get all the best savings here.... boooo).

Titanium exhaust (like 0.5mm wall thickness, something stupidly thin), like they said, saves like 40kgs...

Make all the panels out of carbon fiber, paint them as normal with ultra thin nano paint (place it on 1 atom at a time.... It doesn't take that long, really, you only need 15 atomic layers to close all the gaps, its not that many atoms. Plus if you start now you'll be done before the Orion project is running out of stock).... Supprisingly, this saves around 5kgs (paint is heavier than water, you use like 6L of paint on the car I guess...), now you only use 800ml! Thast goto be cheaper too since you're using less! Place these pannels over the space frame doors, rest of the car.... Stuff.

Then do all the boring things....

Then add everything on as normal (you would have to change the suspension though, since the car will now sit about 2 inches higher).

If you did that (wont cost you much, let me know how it turns out when you do it), you'll save around 400kgs of dry weight, still with all the luxuries! Brilliant!

Now get to it.

That should do the trick, hopefully it helps you decide what to do.

/me is at uni and very bored.....

Faaaarrrkkkkk.......why do you have to type so much?

Can someone do a concise version for us simple-minded folk?
