So my only complaint with my 04 3.0i manual is at high speeds like 70+mph the car seems a bit unstable like I would say easy to sway side to side I guess, anyone have any suggestions for upgrades to stabilize the car more during highway drives?

My first thought would be tyre pressures are incorrect - but as others have said on here, could be worn suspension and/or shocks that can also cause a 'floaty" feel

Tire pressure is good, suspension definitely needs an upgrade. Was looking at the bilstein B16 full suspension costs like $1,635

Very likely worn rear trailing-arm bushes and possibly front arms as well. Try those first (in that order) before spending on expensive upgrades which won't fix the problem.

Have you still got the runflat tyres fitted? If not, do you run the replacement tyres at the same pressures?

They’re notorious for tramlining, loads about them on this forum - most owners report a vastly improved drive after changing to normal tyres.

Do you recommend any tires for this model that would be a good replacement? And I’ve heard to keep a bottle of quick flat fix bottle in your trunk if you do switch to normal tired
