[Fot] Adjusting front camber on a TR6

[Richard Good]

Jim,

Reversing the upper fulcrum from factory orientation pulls the control arms 
in 1/4" and adds about 1.3 degrees negative camber if I remember my 
calculations correctly.  You can do it without removing the control arms 
from the fulcrum.   Just remove the four bolts holding the fulcrum to the 
tower and the two bolts through the ball joint and remove the whole 
assembly.  Then hold the fulcrum and spin the control arms 180 degrees then 
bolt the whole assembly on the other side of the car.  This keeps the front 
control arm in the front but reverses the fulcrum.

Preferred camber will depend on the tires.  The Hoosier A6's that I run for 
autocross and hillclimb want 3 degrees.  They are 225/45-15 on 7" rims.  To 
get that much camber and to keep the tires clear of my unmodified fenders I 
reversed the fulcrums and then slotted the bolt holes to slide them in even 
further.  I just took the worn out tires off and the fronts wore fairly 
even.  The rears were also set at 3 degrees but wore more on the inside from 
squatting under power.  I backed it off to 2 degrees to see how that works 
out.  Also changed to a slightly stiffer spring.
