That sounds like it's on the money Gaz-Gaz!
Bear in mind that a lot of folk spout complete tosh when it comes to the weight of their car... and it's 0-60 times 
It's Evolution Baby!

So true! There's manufacturers weights and real weights. Speaking to Westfield they said that their fully caged cars come in at 700kg with
comfy seats/double side impact bars etc. I bet they didn't say that to many punters though.
Caterham quote their car weights dry in the lightest possible spec. It seems some companies make it up completely.

If your gonna shed weight then IMHO you should be looking at unsprung weight first. This will make more difference to your A-B times. Wheels,hubs, and
uprights etc. Then look at things like battery if your not already on a bike one etc. If you can afford carbon, then some body parts but I'd
look at everything else first!
Hope thats of some help

RGB front engine car with driver min weight 530 kgs MNR dabbled in RGB and I would be surprised if the car weighed any more than around 540 all in at
race end.

Sounds good, I have a fullcage on my striker and will be pleased if it weighs in under 600kg when ive finished it.
More importantly, whats the corner weights?

what kind of battery are you running?
Wheels are tyres are often heavy as there are 4 (or even 5) of them. ACB10 and 13inch revs come in at 9kg a corner which is one (rather dangerous)
way of lowering weight.
Cage adds about 10kg, full of fuel adds 20kg. 500kg isn't a bad target.
Mine was about 475kg at SVA, not sure now, but probably a bit more.

Weighed mine at 450 but a nice light R1 no cage or luxuries other than a boot box. Maybe lose the seat for something more racey, shorten any
pipework/wiring,make any steel bits out of ally but i doubt youll notice anything. probably easier and cheaper for us drivers to lose weight:-)

Seems a bit heavy for a BEC.
Is your cage a bolt in jobbie? If it is and its built to 'the book', I believe the procomp one is of the order 13 kg lighter, depending on
the exact design of course.
As Strontium Dog says removing weight from wheels/brakes/hubs/uprights/front wings/calipers/tyres etc will have more effect than the from the sprung
weight. I don't know what the sierra calipers weigh, but I was shocked that the mx5 fronts I have were more than 5kg each (with pads) Some of
the light alloy ones are not much over a kilo. Smaller wheels are lighter but not as good looking as big ones, so if you've got large wheels
they may be good to change.
Unfortunately the cost of relatively small weight reductions is very high!
Best of luck
Hugh

Does sound a tad on the heavy side. Greatest weight saving would be to swap the front Sierra vented discs and calipers for lightweight calipers and
solid discs. Next, replace the cobra seats for lightweight GRP ones and look at possibly changing the wheels for lightweight ones. After that, other
weight savings become increasingly expensive for little gain

i cant remember the exact weight but it was around 140kg each side on the front axle and 120kg each side on the rear.
the battery is a small bike item.
removing the seats and putting something lighter in is an option, what is a good value lightweight seat?
the protech suspension is being replaced with some very lightweight custom made Quantums, when i get my finger out and finish them,.
i had thought about changing the brakes for a Willwood kit or similar, perhaps the 257mm kit rd sell, any recommendations on this?
i currently have 14" Speedline wheels on there but i'd happily run a 13" wheel as i actually prefer the smaller wheel look on this
type of car, i'd need to see how much the current wheels weigh.
The cage is fitted and welded on by MNR before the chassis is delivered i beleive.
Carbon Panels are out of the question, the only reason i bought this type of car was to save money after 6 or 7 years playing with Skylines
GTR's, Evos and RX7's.
