Just thought I'd post a pic to ask if any of you out there have tried to dramatically lower the weight of your z?

If so, what did you get it down to?

And more importantly where did you take the weight out from?

heres what I mean:

From memory I think Daniel Moore got his 240z race car down to 980kg with half a tank of fuel and him in it.

Fibre bonnet, perspex rear glass, no heater box, whatts as rims etc.

He runs DJM automotive & is a member here.

My Zed, check the avatar is 960kg ready to hit the track with 40l of fuel and me not in it, add extra 105kg for me :shock:

We have done the following to the car to lighten it:
:arrow: Stripped interior trim, leaving dash as standard, including all instruments
:arrow: removed heater box
:arrow: 'glass bonnet and front bar
:arrow: all windows except windscreen glass is replaced with lexcen
:arrow: removed all sound deadeneing and bitumen from under car, one of the worst jobs imaginable.

I still run the following steel components:
:arrow: hatch
:arrow: front guards, however these are very thin and a re actually lighter than fibreglass, also are damaged less when hit, or hit something..

Other weight is saved by using a R180 diff plus the brakes are lighter than standard, using Willwood calipers up front and Saab down the back.

The exhaust exits out the side saving some weight.

We also only use about half the number of bolts the factory did to hold things together, ie front guards held on by not much more than hope a prayer and about 6 bolts.

Wheels are two piece light weight alloys to also help save some unsprung weight.

Extra weight is put back with fire extinguisher, cage, and strut brace plus stitched seam welded front.

also in the latest issue of race magazine (aussie mag) there is an artical on lighting your car and the guy who does it is doing it to his zed.
Has costs and stuff aswell

hehe...looks odd with all those holes. The first thing I thought is whether it's worth the compromise of so little weight loss in regards to the reduced structural integrity of that section of the car. Maybe the owner found this out the hard way when they dfrilled into that rear strutt tower as they've added more weight than removed with that little brace!???

I've never raced cars but on a serious note, at a competative level do drivers get to a point where their own weight loss becomes an issue???

Toecutter get on the LS1 / FPV Forums and do some searches on weight reduction - I dont know if people are joking or what - but "lose some weight ya fat bastard" popped up more than once.

I accidentally drilled some holes into my doors for my sound system, I was a little shattered afterwards. But I should have thought more possitively, the car's a speed demon now that I offed that extra weight lol.

Man you guys make me feel fat. Im 103kg. Im twice the weight of the missus though :D:D Then again I am fat :D

The bloke I bought my Simmons from on the Westsieed had taken out the boot metal or something because there wasnt a boot, just the shape of the bottom of the car. Had a few strengthening things in there but the main one was the crazy cage.

ok guys just to put it in money terms

The race magazine I mentioned actually did a cost per kilo on the zed they lightened (cromole cage, acrylic windows, lighter wheels etc) and they worked out it was $200 (aus dollars) per kilo!!!!!

So I think you guys might have a few grand worth :)

Well as I said take a big dump and save! If you win the race by only half a car length your big turd will have made all the difference! :D :D :D
