But there is always stuff you could do to it like a Fibre glass bonnet, light wheels, light spare or none at all, small battery, different front seats, no sunroof/stereo/towbar/big brakes etc. Link to comment Share on other sites More sharing options...

_Spin_ Donating Members 695 Member For: 17y 10d Posted 21/02/10 08:30 AM Share Posted 21/02/10 08:30 AM Think of it: the car is made from plastic where it once was steel, and lotsa alloy too. Where does the near 2 tonnes come from? The bells and whistles, air bags and sensors and kilometres of wiring.You`d have to gut it like a fish.Okay, going to the drags? Loose the spare, jack and liner. The back seat if you can be farked and anything unneccessary like CD`s, the street directory etc.As an aside, I always marvel at high dollar drag cars with carbon fibre this and fibreglass everything else with swiss cheese hole saw work all over it.Then Clarry who wieghs 150 kg wet climbs in.I mean, I`m not slagging big folk, but sh!t a brick, he`d prolly spend 7k taking 10 kg out of the car..

_Spin_ Donating Members 695 Member For: 17y 10d Posted 21/02/10 09:33 AM Share Posted 21/02/10 09:33 AM (edited) I was just pulling a figure outa me arse 7 grand for 10 kg, but you see the point.I`ve seen lil ride on lawn tractor batteries used. I wonder that I would.You can get fibreglass all sorts of panels, but fit and finish can be an issue. You can make anything work, though. I`ve seen a few fibre and carbon even looking pretty decent.Legality and insurance may rear their ugly heads.I`m somewhat concerned about say, a stock bonnet is designed to crumple. I`d be scared a carbon bonnet would come through the screen and cut my fool head off.But that's just me, sh!t does happen. It has happened..Up to you guy, but yeah you need to google and then contact. Edited 21/02/10 09:34 AM by _Spin_ Link to comment Share on other sites More sharing options...
XR6TWolf Donating Members 176 Member For: 15y 8m 4d Gender: Male Location: Wellington New Zealand Posted 21/02/10 09:41 AM Share Posted 21/02/10 09:41 AM I've been quietly headed down this track myself.First step was lightweight wheels....aside from the obvious weight reduction it is also UNSPRUNG weight so the handling characteristics change quite dramatically. Most on here seem to have fitted aftermarket wheels of some sort so with a little extra expense you can have ultra light ones.Bonnet is pretty heavy. A Carbon fibre XR8 bonnet weighs a mere 11kg. Not cheap but looks good. Added to the bonus here is the fact that the weight of the bonnet is both high and frontward so benefits are obvious.One of the most over looked options is exhaust. Has anyone actually taken the time to weigh one of the factory suckers? It is insanely heavy. Once again exhaust is one of the frequently addressed things by most on here so if you plan on replacing it then weight savings can be made there too.Next most obvious in my books would be the front seats. Big, fat and damn near require a forklift to lift the things. All those electrics come at a cost!!I know many on here scoff at the idea of weight reductions, the most common theme being that there is minimal benefit to be gained from significant expense. Personally I dont agree. I feel that well planned weight reduction, particularly when targeted to the right areas are a no brainer.Skirts, spoilers etc are there for a reason so aside from upgrading to F6 wing and skirts I have left well enough alone in those areas though if anyone ever finds a carbon boot lid at sensible pricing I will be in.
