Ooh, a typical problem. People used to say my TR3 was twitchy at the end
of the straight, just because it would occasionally jump ten feet in one
direction or another. If you're in the lead with a bunch of expensive cars
behind you it can be a real advantage.
I mellowed my car out by softening the rear springs. a rear roll bar will
also make the back wheels steer more, and that's another good reason for
not having one.
Triumphs all have a lot of bump steer, so that may be part of the problem,
but not likely if your front springs are stiff enough (most TR3's don't
bounce around that much).
You have to do a lot of work to really get TR3s to handle and stop
darting, most of which has been discussed at length. I suggest you search
the archives
You probably want a little toe in. Toe out will definitely make the car
leap around, neutral is probably almost as bad. I don't remember what I
used, but it seems like it was a fair amount--maybe 1/2" measured at the
tires, front to back. I know that's kind of rough, should be in degrees
and all that, but I use an aluminum bar with stands and right-angle ends
to do my measuring. Sometimes just string. But I make up for it with a
really cool Camber gauge.
Hello All:
I got the TR3 race car out of the falling down shed to move it to the
"garage" shed so I can work on it for Mid-Ohio. Some mice are looking
for their home. I drove the car on the road a little.
The Darting Around Without Driver Input is worse than I remember it
being. I have to constantly make steering corrections. The blue TR3
feels like it's on
rails compared to the race car.
John Hornbostel, do you remember when this started or did it always do
it?
Is it bump steer? I am not aware of the darting being connected to
hitting a bump, but it might be.
Is there a fix or is it the kind of thing we just live with?
It seems that it wasn't so bad in the driver's schools as it is on the
road. adrenalin?
The front suspnsion has lowered springs, Delrin bushings, and a 7/8"
sway bar. I think it's stock otherwise. Could the lowering cause bump
steer?
The car had lots of toe-out when I got it. I set it for zero toe-in
myself with a bar I got from Moss. It didn't seem to help much. I could
have screwed it up.
Any help would be greatly appreciated.
