Henry,
This looks like a toe in / out problem. If you lowered the car and
changed the geometry on the upper a-arm then you need to check your bump
steer. It will affect the toe at different suspension heights. For
instance I noticed in pictures of my 6, powering out of turns, it looked
like I had too much toe out. I had the bump steer checked and corrected
and the problem of the strange tire wear almost went away. BTW I have
the same kind of sway bars front and rear and my car still rolls
somewhat.

Now I am wondering if the car will be OK riding in the trailer on those
tires! ;-)
Wondering even harder how our fearful leader Joe survives running
his....
ahem, tire program! <bigger grin>
The quantity and quality of the replies I have received has been
outstanding. I appreciate everyone's responses. The consensus of
everyone's
opinion is I have been running overinflated and with too much camber for
my
setup. Here's what I run.
The front end is lowered with a pair of those great Triumph Competition
Dept. springs. You can tell them from stock because the coils run
counterclockwise going down, opposite the stock springs. Massive sway
bar,
perhaps too big. Negative camber is achieved by using shortened upper
A-arms, supplied by uncle jack's racing service. With my car sitting in
a
line of TR4's at races, comparing the front camber to other TR4's, mine
looks to have less camber than others. Michael Porter I think may have
put
his finger on the crux of the issue, my big front sway bar is keeping
the
car from rolling in corners, so I don't need as much negative camber
dialed
in. I wish this was an easy adjustment on a TR4. Would make life so much
easier...
I have been running cold tire pressures at 24 front and 23 rear. I have
experimented with lower, and didn't think it felt right. Looks like I
will
be doing more experimenting this week. The Frye Racing Program has not
started the tire temp thing, so I have no idea what the tire temps are.
Looks like another gadget for the trailer is needed.
I have the tow set to about 1/8th in. My plan is to buy another set of
tires and set the toe to Zero before they see the track.
Thanks again, one and all.
