Some time back I posted that my S2 V8 was wandering all over the road and I was looking for a solution. I climbed under and over it checking bushes, steering dampers and tie rods.
I had just put new tyres on the back and at the same time fitted a UHF radio to the roof console taking the constant power for the radio from the interior light supply, and I wondered if I might have upset the ACE sensor up there or done something to the suspension.
I hadnt taken it on a high speed run until last Sunday where I almost **** myself trying to control it on a winding road at 100kph (60 mph)
I had my second spare in the back as we were heading outback and I checked its tyre pressure and thought while I was there I would check all the pressures, and low and behold, the new tyres on the back were inflated to 52 psi !!!!! Obviously the tyre bloke had pumped them up high to seal the bead on the rim like they do, and forgotten to reset them properly.
After setting all six tyres to 36 psi, I went for a high speed blast and found my old stable S2 was back and cornering brilliantly again. What a load off!
It would appear that the super hard rears were tracking on every little ridge on the road, squirming around as they followed every little contour, and out here with 100s of tons of road trains all the time, the roads have a lot of little ridges.
So..problem solved... I thought I would share this with you in case anyone was having similar difficulties. I never thought that it would have such a major impact on the handling.
