Help front end problems

[SVTvert04]

Last couple weeks car has been getting worse, not sure what is wrong but when driving car feels like it wants to float side to side. Steering feels tight but when hitting a bump or high speeds 60+ you can really feel car getting loose. Hopefully someone can help. Thanks
Just trying to find out wht I need to do or replace 04 cobra

put the car up on the lift, check ball joints/tie rods. also all your bushings (control arms/sway bar ECt)
Also check tire pressure
