Hi All.

Have an old Westfield SEiw, that I have started to use for hill climbs. It was mentioned last weekend that my wishbones are not horizontal,in fact they angle downwards. Which looks like to me that the car clearance is quite high. I can see that by adjusting the spring height I can get them level. I presume that this will alter the camber? in theory I know how this all works , but have never done it. Any tips or suggestions would be gratefully received. Technically I am ok , and have decent work shop, I know I could run it down the road for some one to sort , but a lot of my enjoyment is doing these things myself. Thanks in advance.

This is what I used:

A good set up will have the top wish bone angled slightly upwards towards the wheel.

If the bottom ball joint is bolted to the top the bottom one, it will angle slightly down towards the wheel - so if you draw a line through the centre of the ball joint and centre of chassis mounting point this line would be parallel to ground.

The wishbone parallel to the ground thing is bit of a paddock myth, but getting the ride height down to lower the cg pays big dividends so you may end with the lower wishbones parallel to the ground or angled slightly upwards towards the wheels.
To lower the car basically you just screw the spring platforms down but this will have an effect on camber, toe-in and corner weights.
If the camber is wrong you throwaway grip, if the corner weights or toe-in is wrong you get evil handing.
The ride height, camber, toe-in and corner weights should always be set with the driver or equivalent weight ballast onboard. They shoud always be set then re-check in the same order: ride height, camber, toe-in and corner weights.

Keep in mind lower profile tyres will also lower the car
