'only' a quarter tank of fuel and Jonb said he had 3/4 so no ones hiding anything.And being good friends with Jon we have already talked about it, his is lighter in some areas and mine in others, so with his tank full and mine my car is probably 20-25kg lighter, which considering the heavy bits on mine I could probably make mine 60-70kg lighter than his, which would be a sub 1100kg car on full fuel.
On top of that you could start spending some cash with panels etc and make it even lighter.
I tend not to run full fuel on a trackday and take a few jerry cans.
I do around 7mpg on a dry track too so filling up is a regular thing.As for weighing the only real accurate way is on some corner scales, and decent motorsport place or similar will have some, definitely worth doing before you attack the car, I wish I had!
I just posted this as realistically teh only money I have spent is on light wheels, which in itself is relative as they are probably heavier than the standard 15's, my point being you can endow your car with terrific performance for no cash at all, just a bit of graft and as long as you accept your car will be rubbish on the road!
