Lightening the load

Before Brands we smoothed out the new front end into the bonnet and cast a mould. This meant the front was even heavier than before, but it means that we can now start the next step, reducing the car by 30kg! I doubt we will get this Fury down to the 530kg, although it would be very easy by just remaking all the bodywork, but the amount of time it takes will hold up the new car. But remaking the front endand using the lightweight front bonnet we have should reduce the car by about 10kg without trying too hard.

The front undertray was a bit battered n the existing front, plus we wanted to leave the existing front entact as a spare, so we made a new undertray. This was done with our existing mould, just a piece of hardboard and some D shape trunking. we tried using 2 layers of 300GSm this time, but it was just too floppy, so added another layer to the bottom surface, which also closed off the open sections left by the trunking.


Its looks good and very strong, but has turned out only marginally lighter than using 5mm ply, so next car we will use ply rather than going to all this effort!

Next up was the actual front end, 2x layers of 300gsm, with an extra single layer strip around the edges, produces a great piece, strong enough around all the curved syrfaces and corners, but the flatish front was still ver soft and would break if just pushed in with a finger. Adding another single layer to just this area increased it rigidity by about 3 times. With all the brackets and braces added the front is very stiff and only weighs 6kg, compared to old front end weighing 14kg! The lights are still to be added, but we should have saved 7kg making this front end!!!




Dads on holiday this week but will get it sprayed for Cadwell. Meanwhile i will be checking the car over, cutting down the the lower wishbones slightly to allow us to run slightly less negative camber and resetting all the geo based on this
