[Tigers] Camber question

[Smit, Theo]

Hi Gary,
I've seen the mod where the upper control arm is drastically tilted to
provide a lot of anti-dive... I didn't do that, so I may have created a
monster ;) . I'll have to see if the braking is significantly
compromised by the increased camber gain. If it is, I can always rebuild
the upper towers again to put the control arm in a more suitable spot.
At some point it'll be worthwhile to analyze the benefits offered by all
of the various suspension designs and decide whether to build one from
scratch.

The camber gain is good for keeping the tires inside the fenders,
anyway. With the stock spindles and 16x7" wheels I had to use spacers to
keep the tire rim from hitting the upper ball joint - things were in
exactly the wrong place.

	Hi Theo,
	Lowering the upper fulcrum mount was a trick from the 60's.
	I was told "we don't do that anymore" back in the 90's..
	Do modern tires still like that?
	My read on it was that the new thinking was to increase
	caster so you get more camber change only on turns, changing
	the camber curve caused less tire footprint under braking.
	????

	If you mean "tire-shredding understeer" when you say "twitchy"
then
	you're probably right. The steering effort would also be very
light,
	mostly because there's not nearly enough tire touching the
pavement. I'm
	going to start with about half a degree negative (205/45-16's on
7" wide
	rims) and see where I have to go from there. When I rebuilt the
front
	crossmember I lowered the attachment point of the upper fulcrum
pins,
	and that should give me a better camber curve (more negative
camber for
	a given amount of suspension compression) but we'll see what
actually
	happens. In the limited amount of driving I did with the car a
couple of
	weeks ago the steering effort and stability seemed OK at least
up to
	60-70 MPH.
