lightest 172/182?

[W17GLE]

Who's got the lightest? Mine currently stands around the 940kg mark but i'm aiming to get it down to around the 850kg mark.

if you have had it weighed what have you done to get it down to that weight? Currently i've removed

• all interior
• head lining
• dash
• started cutting wiring in the loom

i was thinking what else can come out and all i can think of is the following

• Air con setup
• rear wiper assembly
• cut out rear seat mounts and metal around the doors and boot

Has anyone taken it any futher than that? if so what?

There's was thread already going in this section of people's weights, think it was this section too IIRC,might be worth searching for.

By all interior, I'm guessing you've got buckets? Could save 40-odd kg. On ph2 there is a chunk of metal near the engine, think under one of the mounts, about 5kg IIRC, not sure if this is on the ph1. What about lightweight wheels? Will save on unsprung weight too which should aid handling and braking.

 

[jesus]

Light wheels are a good shout, have you thought about removing the sideskirts and other bits like that?

 

[Jamie]

How are you going to lose 90kg when you've already removed loads of heavy stuff? Sounds difficult.

The air con is aprox 30kg. So I guess that is 1/3 of it.

 

[Dave..]

I think 480bhp may well have the lightest car once he's done with it. That things going to be a weapon.

yeah i did, i also thought about doing a 1.2 rep for a laugh so i could cut holes in the bumpers. There is no way i'm cutting a ph1 172 bumper.

thats the difficult bit. all the metal around the doors and boot would add up to quite a bit. i could fit an alloy bonnet to save a bit more.

 

[Jamie]

Plastic windows would save a chunk of weight. Just getting the parts s/h and for a decent price.

I'm not idea how much lighter they are, but mine is feather light. Have a look at it next time we're both at a meet.

they are quite a bit lighter than standard steel ones

my car was on the car scales after been rewiderd. came in at 803kg. i have removed all heaters and fan blowers, but replaced them with a heated front screen. all aircon system is removed. still have glass windows which could be replaced with plastic, and also wanting carbon bonnet and boot in a year or so, so should save weight there.

 

[Bazzon]

480bhp's car will be the lightest i'd imagion, Burps was light before he took it apart, he had done some clever things to save weight.

Our track car will be one of the lightest cars as well.
Fully stripped, all un-needed metal has been cut out, all tar ect removed. aircon gone, light weight buckets, light wheels, no arch liners, Perspex window all round. Will be removing a few more things and doing some more work over the Xmas break.

 

[W17GLE]

850kg isn't out of the question then

Sorry but I can't believe a road legal car can be this light is this a dry figure so without any fuel, coolant, oil etc???????

You may well get into the 800's but i'd be thinking of adding a full cage if you start to chop metal out of the car, a full cage will add back in around 40kg's

Also be aware that some of the weights thrown around on here for removing parts are just pure lies, if some of the part weights are to be beleived then the standard clio must weigh 2 ton

Seat's don't weigh 30+kgs
Aircon Doesn't weigh 30kgs
Headlining weighs bugger all

They're all small weight that add up, for instance my Car before i set about the latest changes weighed 990kg's and that's with a full cage and no interior whatsoever, just a steering wheel and one seat.

There's probably 30kgs of steel to remove from the car max, and that includes compromising side impact strength, so adding a cage with door bars is a must.

The glass isn't heavy, 4kgs for a door window, 3kg's for the side windows and 4kgs for the rear screen, that's only 15kg's andd you'll need to replace them with something, so probably 10kg's to be saved that's all.

I've no idea what mine will weigh, but i'll be surprised if it could be made that much lighter, afterall i'm even getting rid of the underseal and seam sealer i'm aiming for under 900kg's if possible.

 

[laxy]

its a track car, no interior ect. i didnt say road car. coolant was full, oil, gearbox oil, was just under 1/4 of tank after mapping!

 

[172Ben]

Standard 172 seats weigh 24.7kg, i weighed mine last week

Fair enough but there's one hell of a difference between a road legal and track car weights so maybe the thread should be ammended as its misleading.

That's an impressive weight, what have you done to acheive that? other than above (i've already done that too)

Looking for tips

[W17GLE]

all the main stuff is out already. its just the little bits now.

 

[laxy]

bare minimal, i spent over 4k getting car rewired by this bloke

http://www.wizardracelooms.co.uk/

he was the guy who put it on the scales also, its unbelievable how much weight was saved on the loom.

other than that made, it was just as everyone else has done. al start a blog on here from where am upto from the beginning when i get 5 mins!

since the 803, i have added a couple of more bars onto the cage and had the inside fully painted so will be a little more since then (april when it was on the scales)

 

[brown4454]

may i ask why you are trying to make the car so light??

for track days?

just to say 'i have the lightest car'?

 

[Daz Clio Cup]

If it wasn't weighed on professional corner scales then you can guess weights all day long......... your local weighbridge weighs 30 ton trucks, it's hardly gonna be acurate for a clio! good for pubtalk, crap for acuracy.
I'd be very suprised if you can get a mk2 under 900kgs unless it is extreme (Chris lol )
mine weighs about 950kg =/- 50kgs, weighed with corner scales but only acurate to =/- 10kgs and it's totally stripped........

 

[172Ben]

£4k on getting it rewired?

 

[laxy]

that included ecu, heated front screen and a couple of other things it needed

 

[Matt@Stealthsport]

I hope that's a typo as its a Clio not a real car

instead of spending loads on tuning to get a few bhp i could save weight for a better power to weight ratio. When i can't get the power to weight any better with the standard engine then i'll start spending on engine mods.

losing weight is free also, and its not like i need any of the stuff in the car.

 

[meady100]

Love this thread! Is there a real difference to handling feel? And what do these featherweights come to in BHP per tonne now? From reading mags, I think the RS200 is about 166 and the new FRS about 187 odd?

 

[brown4454]

for the lads who got there's weighed on corner scales.
what was the front to rear ratio??


is the car going to be a daily driver or track car?

Mines on eibach sportlines and with the lack of weight the handling is rather twichy. i think it needs lowering more with coilovers with custom springs for the new weight of the car.

as for power to weight some are getting close to 200bhp per tonne

the car's purely for country lane fun

by twitchy u mean the back end??

sportlines are more for show, with a big drop, i had prolines, only a 25mil drop, much nicer than standard.

mine is higher than standard even with the sportline due to there being no weight. it was a lot more planted with full interior and at the correct ride hight.

 

[172Ben]

Im about 207-210 bhp per tonne now.

Once i get my bucket seats itll be around 215 ish.

Plenty more to come out aswell.

 

[brown4454]

most of you weight has come from the back??

maybe your to light at the back now to

 

[172Ben]

Most of it yeh, seem very planted at the back when cornering.

Twitchy under braking due to no weight and 4 pots.

 

[W17GLE]

the car is a mess as i'm id way through sorting it but current pics of where its at

Actually Daz, the 44 tonne truck weighbridges are accurate to within 10kgs as well! Tried and tested on our local supplier at work Still not got round to weighing my clio there yet though. Be interesting to know what a completely standard clio weighs.

a lot more than renault quotes, lol

....and the rest!

I'll get a proper figure soon.

I am planning a few mods and will post the weight of my car too and as my friend had a standard Trophy we can compare.
