Have you jacked your car up and given things a wobble about see if any things loose. I know you said you've had your tracking done recently. Doesn't mean they've tightened things back up fully.
Jacking the car up soon to do some exhaust work so will have a wobble then. It is a sweeping corner at say 120mph it gets wobbly and the surface isn't great. It's not uncontrollable I just remember my 225 being more planted at high speed but then that did have coilovers.
Is it the back end that’s twitchy? These cars have a fairly mobile rear end maybe making it feel twitchy? I hope your not doing 120 mph on the road haha.
Yeah I'd say it is the rear end, maybe floaty is a better word than twitchy? Not on public roads, I couldn't tell you where it is. I tend to drive in a random direction and get my satnav to take me home.
Mines feels a bit floaty at the moment and I think the shocks are past their best with nearly 60k on them.
drop links,anti roll bar bushes/link,track rod ends,swivel joints,rear beam bushes,front arm bushes,struts/springs.. always difficult to trouble shoot. I just replaced everything!..but my car is older than yours..
at Bruntingthorpe test ground can see 156 mph one way and 167 mph (GPS) the other and vehicle is completely stable
Mine was mobile on turn in, but that's on demand, depending on your mood and how much weight transfer you play with. It's an astonishingly adjustable chassis yet should be very stable at high speed without lateral load or aggressive deceleration.
