> My main question is to do with lower arm length and geometry. The comment
> that the arm should descend slightly to the strut - is this so that the
> line between the actual ball joint and inner pivot bush is horizontal at
> mormal ride height, or should even this line be descending, hence giving
> increased camber to the outside wheel as the car initially goes into roll
> when cornering, before extra compression starts to reduce camber? If I
> figure this right, wouldn't this feature make the inner wheel change
camber
> even greater under droop as the weight transfers (granted the greater load
> is on the outside wheel) and therefore assist in grip? How much is enuff!

> As for arm length - short arms give greater camber change - is this good
or

of

> I figure the only way I can control bump steer is to buld my own steering
> arms (hence the capri struts - the arms bolt on - and my ackerman angle
> queries) to ensure the steering arm ball joints are co-incident with the
> control arm outer balljoint and the tie rod inner ball joint is in line
> with the inner control arm pivot. (and hence the anti-dive question, to
get
> them all on the same plane - or at least as close as possible)

> Steering will be rack and pinion - I was considering a mini rack housing
> with herald rack and pinion inside (rack must sit behind axle centres -
> hence the mini rack) however if i am fabricating steering arms then I may
> as well use the toyota rack and shorten the arms to get the ratio
> up.Comments? Any thoughts on total turns lock to lock? I believe escort
> quickracks were about 2 1/2 turns. Any thoughts?

> FWIW I reckon the Anglia will weigh no more than 850 kg, and probably even
> less.
