Hay guys. What things can i Remove of my car for it too loose weight off it. I took my spoiler off but I like the look of it better without. I've got an aftermarket head unit. Standard exhaust has been replaced with extractors and catback. What are things that I can do to make the car lighter. Aftermarket lightweight wheels don't seem any lighter than my standard sports 16s. Unless anyone's got any recommendations on some really lightweight wheels. Any comments would be appreciated. Cheers Kurt.

Recaro racing seats would lose a good 20 or so kg off the car.

I don't do this myself because of practical reasons but you could swap the spare tyre for a puncture repair kit or half sized spare. There is another 15 or so. If you have a tow bar you could pull that off also.

To be honest if you are trying to improve the power/weight ratio it's much harder in cars than say on roadbikes etc, purely from a performance point of view.

It would be cheaper in my opinion to look for more torque from the engine rather than try to strip the car down weight wise, there's not enough big kg items that you could remove that would really gave any impact on acceleration.

380 motor :)

I just won't my my car to easily crack high 13 second. It's done a 14.2 on a standard TH ecu. I'm getting a tune very soon. But I'm also looking at lightning my car Abit. Just don't know what I'm gonna do aftermarket seats sounds alright. Lightning a car really does make an improvement in performance. Even loosing small amounts of weight does make a difference.

You could dump the audio gear, wiring and speakers, and remove the heater and A/C components. Any sound proofing you can find too. Replace all glass with perspex. Acid dip panels.

Well where do you start.

if you are serious about weight loss, 200kg should be possible. This is with extreme measures though.

1) Completely remove interior except drivers seat and driving controls
2) Remove dash board
3) Remove door cards
4) Remove sound deadening with a heat gun
5) Remove any excess metal in the interior that isn't structural

In these situations, it is beneficial to add a lightweight rollcage to ensure the car is stiff enough to prevent chassis flex.

If you're just wanting to strip some weight for a run at the strip and then put it back in I would suggest front passenger seat then the rear seat. Both car be done in a couple of minutes with basic tools. Also take out the spare wheel and run your car with 1/4 tank of fuel. If you want to take it a bit further then before going to the drags remove any big stereo equipment like subs or amp as previously posted. Remove the carpet and use a heat gun with a paint scraper and a rag to melt out the sounds deadening on the floor in the cab and in the boot. Personally I wouldn't go to the trouble of removing any excess metal in the car unless you intend this to be a track only car. Also if you're going to the drags often it might be beneficial to try to get hold of some space saver rims/tyres to put on the rear.

It's quite labour intensive but removing all the sound deadening can save you over 20kg.

Don't underestimate the effect of light weight wheels because removing 1kg of unsprung weight has the equivalent effect of removing 5kg of sprung weight in terms of performance.

Mods done. Extractors' high flow cat' catback' 380 camsharfts, k n panal filter-cai. Is the any other power mods I could do there's gotta be something. Thermal intake spacers are known the improve performance. Are they good on our cars?

If all you're after is a 13.something time slip then a 50HP shot of NOS would definitely get you there,just don't have it hooked up on public roads.

Remove the bonnet and bootlids :ninja:

Or replace them with lighter ones :P

How about looking at your suspension..?

Coilovers are slightly lighter than standard.

SuFz :ninja:

definately look at suspension. ultra stiff rear springs will reduce squat on takeoff. Failing that, there isn't much else you can do for little money.

I'm really looking for is a 13 second car on the road Aswell I'm gonna have a look at some mods.

Just removed 100+ kg of audio from mine ready for the drags tomorrow night... lololol POWAH!!! Its silly quick now, kinda makes me wanna remove the seats now to see it get quicker still.

If wheel spin is a problem then look towards a set of second hand Mickey Thompson Drag Radials if you're on a budget.

If not, remove the sound deadening, but put the carpet back in for daily use. Then when you rock the strip, tear out all unessential items and leave them at the gates in a pile.

Look at removing the spare..

Keep a can of puncture repair and tyre in a can.

Coilovers will lose a few kilos for you..

Looking at some XXR Lightweight rims might assist.

Pull everything unnecessary outta the inside of the doors..

Lose your rear speakers..

Lose the boot floors and carpets..

It's not much but there's a few kilos there at least..

If this is only for the strip, can you get smaller wheels and tyres?
EG: if it's possible to get wide but low profile rubber like a 235/40/15, you may have enough grip and less weight.
Obviously this isn't legal on the street, but if it's just for a timeslip, it's one way to go.

I agree, pursue the weight savings as much as you can - a friend pulled tools and spare tyre/wheel from his boot and improved by 0.2 seconds.
I also talked to a guy with a TX5 turbo, he'd just put on drag slicks and knocked 1 second off his time (14.5 down to 13.5).

So if traction and laucnhing is difficult, drage slicks would be great for a time, not so good for clutch/diff/CV etc. And again, only good for a time slip, not for on-street performance.

Are there any aerodynamic mods that might improve times?

Not just lightweight wheels but lightweight tyres. eagle f1 aysm2 weight alother less then a standard tyre.

I won't a car in street trim to do these times. It would just piss me of if the car was only that quick just for the strip then return back to normal. So I've decided a 3.8 conversion is the only way I can easily run 13s. I know my 3.5l would of cracked a 13 with a tune and better tyres but it would barley scrape it in. We'res 3.8l with a good driver will run 13s all day.

Before you throw the engine in throw a cam in it. You'll thank me.

was researching aero and apparently a good way of removing drag is to cover trhe underside of the car (rear bumper acting like a parachute, and covering the engine area).
another trick was to cover the grill over. wasnt game to try that due to it worked in Canada where engines overheating is less of an issue, but if its just at the drags could help?

as for weight removal, i dont think anyone has mention a dry cell battery yet?

Coil overs are lighter than normal springs + shocks.
Replace all the heavy bolts with titanium ones - more practical than some of the above options, but certainly not the cheapest :)

What kinda cam we talking about?

One that makes the valves open more? Xd

Haha very smart arsed response! :p what number cams should people be looking at getting for a 3.5 however?

2 cams required, 1 in each bank.

I dunno a number? something like the rpw stage 2 or similar? as far as i know there isn't much out there. Will work much better in a 3.8 then a 3.5 though.
