corner weights again
I decided to go the Asda way with scales to set up corners(well it is locost) fully loaded they are nsf 137, osf 165, nsr 153, osr 162, total 617.
As you see the nsf is very light even with the battery stuck right in footwell and if I ajust too mutch the car ends up at a crazy angle. Am I doing
something wrong and how even should I strive for any ansewers eagerly awaited as wer'e off to Brands on 19th for first run, Ernie

Just done a bit of maths and came up with the scary solution of...
adding 35 Kilos to the juction of C/F1
either i have gone wrong somewhere or you'd better get tweaking
(I'm betting on my buffoonery being wrong)
why not switch it to left hand drive - problem sorted

With a sport car chassis you can only get so far by trying balance the car by moving batteries and the like after that it is really a matter of
making sure each wheel does it share of the work
With the current chasis weight distribution adjust the spring platforms to aim for these figures ---- not really that far from what you alredy have.
OSF 160 OSR 167
NSF 142 NSR 148
You need to raise the osr spring platform slightly and perhaps a tiny ammout on the nsf.

Other than the battery what elsecan you move about in the chassis, is there room to offset the radiator to the near side?

Trident are you saying that to change the corner weight you should change the amount of preload on the relevant springs or leave the preload the same
and screw in or out the mounting bush positions to give a longer effective length ( or shorter ) from bush to bush. I only ask as i have seen a car
where the ride height was so drastically altered using the spring platforms that the shock absorber was totally compressed when the car was sitting
still.

also are you sure your scales are correct. I've got some asda scales for when i get round to corner weighing my car. Did some checks and some
scales read different amounts with the same weight (me) on them.
And.... are you making sure the suspension is fully balanced / unloaded (not sure the term) ie get the car to the height of the scales, roll it
backwards and forwards a bit to settle the suspension then roll it onto the scales.

Preload is the key (as long as the scales are accurate enough) - moving the spring seats will adjust the corner weights. Try to get diagonally
opposite corners as close as possble.
