I wanted to try and lose alittle weight from my soarer, nothing too crazy as i'd basically like to keep it as a fast road, occasional track car, not an out and out trailer to events car, also i don't want to get defected for anything if i get pulled over.
Can anyone point me to any threads with info on the weights of items etc and what can be removed? So far i've bought a can of emergency tyre inflater foam stuff so have dumped the spare wheel, jack, tools etc. Does the uzz30 have huge heavy iron front and rear bar, bars that can be cut down?
Any info would be ace, thanks.

Did abit of googling and there seems to be some interweb folklore that points to 0.1bhp to every 10 lbs you nremove from the car.
Cheers btw, i've got my eye on some seats, how much can i strip from my car and still keep it legal? can i remove all the trim, carpet, sound deadening etc and just have the car as a two seater?

yeah but then you probably wouldnt want to drive it. just keep the nice interior stock and spend some money on performance upgrades if thats what youre after. Do you really want to get around in a car with no carpet?

I've removed the AC, heater, stock CD changer etc, cruise control,Supra set are about 30 kg's lighter overall, CF bonnet,stock exhaust weighs heaps replace with 3 inch system, rear window wiper,moved battery into the boot,rear seats,all the stock fans and replaced with ally radiator and IC with thermos,wiper water bottle( just left the filler so it looks like I have one). Still got to do carpet insulation and door skins and rear speaker, which I am putting off as I still want to drive it on the road.

In a soarer if you lost 75kg luck to be 2 tenths in it 0-100km/h
Braking and conering would be more improved than straight line
actulay I'd say the difference would be so low that 0-100 times would be hard to distinguish on a g meter...
My car with 20's (40kg heavier than the TT16's) and subs spare and Jack etc... About 70kg all up... Compared to stock rims empty boot the data was in consistant and neither better or worse but on average the same.
But it did handleand ride much better and also stop better as well as being 1l/100km atleast better on fuel.

1640kg's - 191kw's
every KW has 8.5863874 KG's to drag around
1570kg's that drops a massive 366 grams per Kw.
To see any significant performance improvement you need to drops hundreds of Kg's.
Leave you Luxury sports cruiser the way it is, unless your turning it into a Track car.
And Andrew , "better" is a such a subjective term. With 20' wheels , you are probable getting better grip from a larger contact patch on the road, but you are also benefiting from the added inertia of the heavier wheels and the larger rolling diameter , to give you better Fuel economy. BUT !! , you will suffer from less compression dampning and less rebound dampning from the 10kg heavier wheels, your suspension is probably struggling a little to cope with the added weight at each corner. Plus you will have no side wall flex from the super low profile tyres to help with harsh bumps and help in cornering and i suspect more understeer when pushing hard. I make this point to show that everything has benefits and also a down side, everything is a trade off. Each to their own but.

Remove GPS/CD stacker/tuner/reciever units (replace with simple head unit wired directly to existing speakers) - 10+kg saving
Exhaust minus centre resonator and middle mufflers - 15-20kg saving?
Lightweight wheels - 8-15kg saving
Thats probably as much as you could get away with, im going to guess around 80kgs is a realistic figure over a completely stock UZZ31
I wouldnt pretend this is going to give more than a slightly noticeable increase in performance though - the real gains are only made when you abandon any idea of daily-driver usefulness. My track car is well over 200kg lighter than it was stock, and still more to come.
And btw the front and rear crash bars are aluminium and dont really weigh that much that it would be advisable to remove them on a road-driven car

my G-tech meter on a stock TT soarer showed a consistent improvement of between .2 and.3 of a sec when driven 0-100km/hour, when a 75kg person got out of the car.

Why not just leave it the way it is and drive everywhere with only 10 litres in the tank.
c'mon guys , if you want to see any real performance improvement, you need to sacrifice all of the comforts of the car.
if your going to get serious about this , lighter battery , go for a fiberglass bonnet & boot, ditch the leather/adjustable/heated/memory seats, ditch your spare tyre, spend $3,000 on decent lightweight wheels, get rid of the aircon / air suspension/ heater core / stereo all together. ditch the rear seat. that will probably be around 200kg and make the car about 0.5 seconds quicker, and I'll bet you'll be selling it about 3 months later , because the police now love you , and you can't listen to music, you can't drive in comfort on hot summer days/ cold winter nights / in the rain because your windscreen fogs up, and god help you if you get a flat.
c'mon guys , right tool for the job , its a Sports luxury cruiser, not a track car , not a race car, not even a sports car.
If you want to improve the performance , you could always just add to the car , rather than take away. A good place to start is to spend money on the nut behind the wheel - Driver Training.
