I'm leaving on vacation and I got so many responses to my post about
anti-roll bars that I will respond in general. Thanks to all who checked
in with advice.
Near unanimous recommendation was that for solid axle TRs, a front bar
improved handling, but a rear bar did not. Some said that adding a rear
bar caused oversteer.
So, I will buy and try a 3/4 " front bar from TRF for the TR-3A.
Regarding TR-4As, I have a mildly contradictory report. Some time ago,
I bought a solid axle TR-4A autocross wannabee. It is lowered, has
anti-roll bars fore and aft as well as stiff springs all around, 185x15
Hercules radials, a 4.26 rear end and highly responsive steering. It
corners like nothing I have ever driven in my life, excepting maybe a
go-kart. But it's rough as a cob on a bumpy road. The car has been in a
constant state of repair since I bought it and I only have about a hundred
miles on it, so my experience isn't universal, but I haven't noticed any
oversteer. I would call it mild understeer to neutral. Also, I never
caused the inside rear wheel to lift up in a turn.
(My only real experience with oversteer is my Volvo 240, which has
Michelin radials. Usually it has mild understeer, but in wet weather, it
changes to really scary oversteer).
Thanks again.
