Nick,
Well put
White man speakum truth. Lower arms for major adjustment and upper mounts
for fine tuning.
Cheers,
Feral Errol

Pete,
The angle that the wheel makes with the road when you look from in front or
behind the car is called "the CAMBER angle"
If you want a car to have good cornering power, it is clear that you have
to
have the most amount of rubber on the road that you can.
This is best achieved when the wheel is upright, i.e at 90 degrees to the
road - a zero camber angle.
The key here is when do you want the wheel to be upright?
Because the Datto has MacPhearson Strut suspension the camber angle changes
when the car pitches and rolls.
The idea is that you give the car static negative camber (tops of wheels
closer to centreline of car than bottoms) so that when the car starts to
roll in a turn the outside wheel camber angle goes back to approximately
zero.
So, when you need it most (middle of a corner) you have the front outside
wheel at 90 degrees to the road, maximum grip - yeehah!
There is one more subtlety, if you roll a cylinder it rolls in a straight
line. If you roll a cone shape it rolls in a circle.
If you increase the negative camber angle even more than what it takes to
get the front outside wheel upright in a turn you find that you get even
better cornering!
This is because the front outside tyre squashes into a cone shape. F1 cars
don't have any suspension movement but still run 3 degrees camber for this
reason.
The only disadvantage of too much neg. is increased tyre wear on the inner
half of the tyre, and slightly decreased braking ability - and acceleration
on FWD cars.
My old Alfasud had 3 degrees neg camber and used to get wheelspin going up
hills!
But going down hills and on flat smooth roads the cornering limit was
determined by the rears, the front wheels had that much grip...mmm.
I recommend changing transverse arms to get more neg. camber rather than
buying adjustable strut tops or slotting the holes.
Regards,
Nick
