Hi,
There's only a few ways to adjust camber on the TR6.
1. shims on the lower fulcrum inner bracket...
2. the orientation of the upper fulcrum pin (there's a right way and a
wrong way, the part is asymetrical)
3. spring height
4. the actual verticle link itself
You already know about 1, so we don't need to address that.
Some folks intentionally install the upper fulcrum pin "backwards" to get
more camber. You might check that. Changing it around with the body on the
car is do-able, but it is a major pain to get to the inner bolts when the
engine is installed.
Spring height could be considered too. If you've lowered the car (shorter
spring), as the lower a arm gets closer to the upper a arm, you get more
negative camber. I've seen folks leave off the spring "pads" to shorten
that distance a bit to get a "skosh" more neg. camber. In fact I've done this.
Last is the verticle link. If you don't know the history of the car, don't
rule out this component. If the car takes a big shock from the side on the
front wheel (like being on the "wrong end" of a collision or striking a
curb (kerb for those OTOSOTP) whilst sliding sideways), the link can bend.
Now, while it is possible to straighten the things, be real careful if you
decide to do this (as opposed to replacing the vert. link), because heat is
a no-no and the adjustment is "gross" as opposed to "fine". FWIW, some TR
racers of the past used to put a big pipe on the front axle stub to bend
the link to get some negative camber, but that was more a TR2, 3 and 4
trick, as they have no camber adjustment in stock form... But if a link is
bent - you will have problems getting correct camber on that car.
If the car has been off the frame or if someone has undertaken a major
front-end repair (or rebuild) in the past, I'd vote for two. Especially,
because you mention lowered springs. Sometimes folks install the camber
plate backwards to get tons of camber but then they put in shortened
springs that compound the issue. It's a case of "too much of a good thing".
I'd completely stay away from four unless you are desperate and have no
access to a replacement vert. link.
But in any case, _BE CAREFUL_ and don't make a repair that is unsafe.
regards,
rml
