did u ever find out the answer 2 this

I cut it all out. You can get every bit out apart from the patch behind the heater. But this stops it rattling anyway. All the stuff around the fusebox etc you can get out.

Im liking this thread! all stuff ive been looking into!

Few additions... bit extreme but...

Remove low torqued bolts nuts and fixings in engine bay and replace for Aliminium ones,

cut off the brackets and fixing studs in the back of the car, rear sealbelts weigh quite a bit! Cut off the rear tow eye thingy, its pretty heavy

Alu gear knob... ? lol

Replace all bungs with carbon fibre, remove wheel arch liners (it'll rust like shit though)
BMC CDA is the lightest intake iirc?
Team Dynamics pro race alloys are 6.1 kgs each so pretty light!

I have to disagree with you Maddison though as they track slag look can be an amazing sight! I hated it at first until I saw 'Colin's stripped saxo! have a look if you havent already

Someone else post something else that can be removed ! im really interested in this thread!

only filling half the tank...

what a tank 40 litres?

20 litres about 20kg saved.

Chr15 · 26th May 2010, 23:40

passenger seat so no passenger!

loads there too

frankie · 26th May 2010, 23:43

a good shit and piss...

2kg saved there.

Lippy · 26th May 2010, 23:50

I agree with the petrol idea! i only ever half fill now but iirc my nos bottle weighs about 3 stone lol

on a more serious note (taking a dump aside lol) the airbags etc weigh quite a bit! especially the ones in the sides of the mk2 vts's...

I'd leave the battery where it is to keep corner weights more even. Leave the spare wheel in and get a decent 30kg+ cage and that will help balance the car out after its been stripped. A fuel cell in the boot will put more weight on the axle. You'll notice a fibreglass bonnet, takes alot of weight off the front and in turn more weight ends up on the rear.

Only 20Kg saved sorry.

Petrol weighs less that water remember. It's oil, and oil floats on water.... (.73kg/L)

A full tank only weighs 29Kg if it's only 40L

You also have to remember that despite a full tank adding that weight to the car half a tank would probably be just as detrimental in corners. When you turn in on a hard corner all the fuel would fly towards one side of the tank. Think of it like having a little man inside your car running at the sides when you turn - it could be the thing that causes you to lose grip if your just on the edge.

As mentioned earlier - loosing weight without a proper configuration is detrimental to the cars handling. Unless your going to get a smaller/baffled tank then only putting half a tank in might be worse

AlexB^p · 27th May 2010, 07:14

also if your playing with the weight of the car relocating things helps
as the top gear article shows removing everything from the rear doesnt exactly help get he corner weights better and the car will behave better

battery in the boot washer bottle in the boot move fuse boxes internal to the car same wit ecu ect and you can pull the center of grip back by getting more equal weight on the tyres all round

imo (after heavily stripping 3 cars including taking an angle grinder to one) unless you then put weight back over the rear from the front your going to end up going backwards a lot as the car gets skittish if not set up right or on budget stuff

as a result of this lot ive concluded in my car to leave most of the interior in and replace body panels with fobregash and windows with polycarb relocate a few things and be happy

past that then really unless you only want to save 0.003 of a second a lap then imo theres no point unless you plan to fit a cage to put some weight back in

sunroof ! Thatl save some ! Get a non sunroof skin or carbonfiber roof ! Not cheap tho !

jsdvtr · 27th May 2010, 13:36

Is it worth cutting the underside of bonnet or save and buy fibreglass or carbon?

The sunroof part of roof, the part which it sits in that drops down with hex screws in. Can they be undone so the flat with hole inside or can you not get rid of that part as its in way of my cage getting welded in properly atm, but if can do that i might get a carbon blank for it.

adamskiTNR · 27th May 2010, 13:45

The saxmax at college has the hole filled in, so yes the sunroof frame can be removed

i know what having it stripped out is like, mine was completely stripped out for about 18months, no carpet, doorcards, even no passenger seat. absolutely everything inside the car not needed was ditched short of the heater matrix.

it makes the car 'feel' quicker but its mostly in your head because of the increased amount of noise, when you put it to the test on track i was gaining 0.4 of a second over a 1/8 mile drag strip which is a lot on a drag strip but its nothing on the road.

more often than not having it stripped out looks scruffy, untidy, cheap and nasty. it can look good but if you're doing it for the image then thats gay.

i put all the interior back in as its very rare that i track my car anymore, back when it was stripped it was on track every month so i saw a purpose in leaving it stripped but now i don't i'd rather have a little comfort and to be honest, with the power its pushing now, losing 20-30kg won't make much difference!

so in short, yeah it can look 'cool' but for an everyday car that doesn't get track used, no thank you.

webby · 27th May 2010, 13:57

only a few trackdays a year leave it alone imo,

i have a couple booked and the only thing i will be doing is removing my sub and amp, not so it's lighter so i dont have to worry about it smashing free.

christ i think the car now is rattly and noisy i couldnt stand it stripped out as a daily drive that isnt seeing alot of track action whatever that maybe

oz_ · 27th May 2010, 14:09

Oh yeah, I'll dig out the sunroof from the shed and weigh it for everyone. It does weigh a fair bit. Especially how high it is in the car.

I used a road sign I found in the hedge to cover it. Makes a slight 'bong' when I shut the doors now!

Yeah, remove everything that is not legally required, compromises structural integrity, or mechanical necessity to drive the car. Everything else can go.

keep that in mind when you all strip it out for that 'track slag' image.

Yup, have tried to find this to reference it, and here it is;

This is very important reading to everyone who is thinking of stripping their cars.
