I put my hillclimb/sprint v3 type RA on a weigh bridge today and it came in at 1210kgs with full 6 point cage and a full tank of fuel. Does anyone have any idea what these weighed out of the factory, or has anyone weighed their classic. Have my weight saving efforts worked is the main question?


Cheers Rob.

 

anyone?

 

MY00 Classic turbo with quarter tank of fuel weighed in at 1280kg on a local weigh bridge.

 

Pre facelift = 1180Kg
Post lift 1210Kg

 

As far as I know the RA is 1230kg's.

Regards,
Shaun.

 

lol - who knows then.

hope it helps

 

1,170Kgs. for the early ones

 

Wouldn't it liek depend on how fatty pants the driver is

k sorry

 

No.
Most of the weights quoted are for a dry (and empty) car.
My numbers came out of the Haynes book on Imprezas.

It was a joke

 

MY95 STI RA, full interior, spare wheel, jack etc, Air con and central locking (on an RA, I know)

1250 with a full tank of fuel on my local weighbridge

 

Pars: Sorry, did not mean to take the comment seriously. Reply from me was too short!

Most cars are weighed free of petrol and even oils sometimes in official data sheets.

 

ahh, so with all fluids including full tank and 65kgs roll cage thats not a bad figure for my efforts. ok who wants to sponsor my carbon prop, bonnet & wing mirrors?

 

or offer any advise on cheap weight saving measures whilst keeping the car a nice place to be.

 

Subaru quote 1190 kilogrammes curb weight for a September 1996> (D-Series) WRX Type-RA (A-Series cars weighed 1170kgs and C-Series cars weighed 1180kgs.).

Plastic doors, boot lid, and perspex 'glass'.
Light Rays wheels
Light flywheel
Take it off the road and really do it right.
Buy a trailer.....

About £1500 I recon.

Graham

 

got the light flywheel already, I don't really want to go down the trailer route more hassle and expense. Maybe in the future though.

Would a carbon bonnet offer any saving over the stock ally one?

Rob.

 

Yes; if you can get a decent pre-preg one. Most arent though; theyre laid-up and they may well weigh more. Its one of the last things that Id do myself. Have you ditched the spare wheel and tools in favour of tyre treatment? Thatll make a more substantial weight saving for a lot less money. The tyre treatment is sold at quite an impressive mark-up by LPG convertion firms (used to allow the fitting of a doughnut tank in the spare wheel well); but it can be bought relativley cheaply if you look about.

As well as a lightened flywheel you can fit lightened engine pulleys and maybe a composite propshaft.

If you really want to do it properly you need to remove all of the underbody seam sealer (thatll be a good time to seam-weld the bodyshell. weld and inch leave an inch will do it); along with all of the jute-backed sound deadening whichll be stuck to the cabin floor. Proper shell prep will enable the car to withstand the rigours of competition: after a while itll turn into a big spring otherwise.

You can also remove all of the central locking motors and the electric window winders (virtually ever RA Ive seen has had them optioned). Speaking of options most have simple aircon too so Id lose all of that. Id replace the front drop-glass and the rear windows with perspex, probably fixed. Id fit transparent film though as perspex scratches very easily. Its more practical to keep a lifter in the front so Id be looking for the manual kit from an early low spec 1600cc FWD car.

Simon

 

Mine didn't come with electric windows, or central locking (saving what, 5-10kg?) but came with aircon (30kg I'm told) - go figure!

Couldn't live without central locking so had it fitted with the alarm install

 

With Carbon fibre it`s best not to keep the car outside all the time. As the sun destroys the resin and you end up with a sharkskin type effect. It goes really dull and feels rough to the touch. I`ve seen carbon fibre kayaks be wrecked in about a year, if left outside.

No electric windows, and I had the aircon removed, which is a rather massive lump. I want the car to retain an interior and not be a miserable place to be as some of the events i run are a fair old jaunt away. I can't see the £££'s for kgs saved being justifiable at this stage with all the carbon bits. I'm really struggling to keep it cool on the standard intercooler so thats my next mission. Maybe the winter will bring some more carbon we shall see.

 

Try removing the sound deadening and retaining the carpets then; I opted for that in my hillclimb car. Consider swapping the glass for perspex too because this gives you a double advantage... You save a lot of weight and you save it from high above the centre of gravity too.

It is possible to take out 150kg without too much trouble.
