Mardave Updated Front Wishbones
 

Any instructions for how to fit and how to adjust?

Seems obvious to me.. 2 middle holes for mounting screws, one outer hole for king pin and extre hole for mounting to chassis via a new hole drilled in chassis.

and various spacers between wishbone and chassis to adjust camber, castor and ride height. the usual mardave simple and accurate solution

Thanks.

How much castor do people tend to run on their front arms?
On my cec I used to use a nylock under the front of the top deck and a flat nut under the rear and this gave quite a lot of caster. I removed the nylock and use two thin washers now but I'm unsure what change its made although the car is driving really nice currently.
I'm guessing with these I loose the top deck but how many mm is the norm?
Cheers

After talking with mr mardave. You keep the top deck but install it flat. And use the washers to give caster and camber.

I used to have 2.5 mm under the front hole to get camber you leave the middle washer out under the front plate...

Using 0.7mm washers the following can be achieved with the new front end:

Front 1, Inner 0 = 1.58 castor 0.91 camber

Front 2, Inner 0 = 3.15 castor 1.82 camber

Front 2, Inner 1 = 3.15 castor 0 camber

Front 3, Inner 0 = 3.15 castor 2.7 camber

Front 3, Inner 1 = 4.72 castor 1.92 camber

Front 3, Inner 2 = 4.72 castor 0.91 camber

Logically I would expect Front 3, Inner 0 = 3.15 castor 2.7 camber to be
Front 3, Inner 0 = 4.72 castor 2.7 camber
