Triumph tr4 supensnion issues -rigid axle

[restevez]

My father is restoring at 1963 tr4 rigid axle triumph. I was wondering if there is any aftermarket conversions avaliable to give it a better ride. Any thoughts

if you want a good "driving" car fit uprated springs and 25% uprated shockabsorbers, don't bother with the conversion to "normal" shocks. Use polyurathane bushes in the spring shackles (back spring mountings).
If you want a comfortable car do the same but use normal springs.
If you want to drive fast and safe think about fitting an antiroll bar at the back, they make a big difference.
Don't go for fat tyres keep to the 165 radials.
If all that doesn't work buy a Stag :-)
