i just put on some Lexion type 203.
FRONT: 235-35-19 these are used with some camber or/and toe wear. the front tires still have lots of life left but the edges of the tire did not get even wear, feels bumpy when run hands over the outsides edges.
REAR: 275-30-19 tires are new

Heres the problem
When I am driving on the freeway going anything around 80 mph the car feels like its floating over bumps and when the steering moves. I understand the GS has the reputation of having a floating feeling when going at high speeds but when I had stock wheels and Tein CS installed the car felt great, no floating feeling and handled great and didn't feel the steering loose on the freeway. Also with the 19in stagger wheels when I jerk the steering wheel left and right a little going around 80mph the car kind of feels like like a boat, sways sides to side (I don’t feel like I have control of the car when that happens) feels like the steering is not connected with the wheels for a second when it happens, feels loose. I don’t know if this makes any sense, if it doesn’t I don’t know how else to explain it.

This problem started after I installed the 19in wheels and i still have Tein CS installed. I also installed BBK on the car but I don’t think that would cause something like this. I rebalanced the front wheels but didn’t help much. Does anyone know if I need a Steering ECU or something? Or New front tires?
or does Stagger wheels have this problem?
