This is just opinion, I don't have any real testing to back it up, but I
find that soft rear springs on TR3s seem to work better. I tried
stiffening the rear spring when I lowered everything on my Cheater TR3,
and the understeer got a lot worse. Of course I was changing about five
things at once, so who knows. I went to softer springs and stiffer damping
and it got better. Then I radically changed the front suspension and the
car handled great. I monkeyed around with a rear sway bar, and that's
gracing my parts shelf now. Also gathering dust is a set of home-made
anti-tramping bars which are probably similar to the torque rods you're
talking about (I suspect). I may have gotten the geometry wrong, but mine
stiffened the rear end and made it hop under acceleration. Exactly the
opposite of what I intended.
Peyote has a fairly complex system of panhard bar and torque rod that sits
well above the axle. Works fine.

Subject: Rear leaf springs
Hello, Listers
I am rebuilding the rear suspension on my TR4 live axle.One of My existing
springs broke next to the eye. I hope it was just age and not anything
more. I
measured all frame dimensions and they appear to be correct. My question
is
"should I replace the rear leaf springs?" I know Revinigton and
racetorations
both have replacement springs . Revington has four different spring rates.
Any opinions as to which rate might be best. They are as follows.
Revington:
Uprated road springs 156 lb./in
Rally spec. spring 160 lb./in
Works Rally springs Rate not given ( Kas any input?)
And Rear road springs with 175 LB/in with 90mm ground clearance with
1000kg.
car.
Racetorations:
listed as replica of works Rally spring.
Does anyone know if the Torque rods fitted to the works cars are being
reproduced? If not does anyone know the specs.? I have access to a machine
shop were they build off road buggy parts. If I had the specs they said
they
could build them for me.
Thank you to the wonderful people of this list. With out you folks I would
not
have under taken the project of building my own TR4 racer.
Cheers,
Patrick
