Weird Handling Issue

[jimmyratsbreath]

Hi Guys,
My Gsr has recently started missbehaving.If I go over a bump it sometimes feels like the backend moves side to side. Sometimes I even have to countersteer.
If I load up a side ie left or right turn it handles fine so really only happens in a straight line. And yet somedays its fine.

Wheel nuts.

Guys, wheelnuts was the first ting I checked. Tyres are near new potenzas, The wheel alighnment guy mentioned something had been loose in the rear end and caused massive tyre scrub on previous tyres.
My baby needs plenty love clutch ,synchros and oil leaks oh and a very rusty roof so once I get two other reliable cars ready I'll restore this one

Rear trailing arm front rubbers are probably rooted like what Brian said. Would be like having 4 wheeling steering, but only 2 doing what you tell them.
