Handling on the Freeway

[Zasker1]

Team,
I recently put some larger wheels on my TSX:
[SIZE=2](- SSR GT-7H 18"x8", +48 offset
- Bridgestone S03 Pole Position, 235/40-18)

and have noticed that since then the handling is terrible at speeds over 60mph. The car is not "Darty" as if the TOE is wrong but it just hugs the contours of the road. I almost feel like I need to install a steering stabilizer as unless the pavement is perfectly flat it now requires alot of driver input to maintain control. I took it into Acura and they maintain the alignment is perfect.
Has anyone else experienced this type of issue after putting on larger wheels?
What did you do to fix it?
Comments/Ideas?

It's a common thing when you put on lower profile tires and bigger wheels. Since there's not as much playin the tires they tend to follow the grooves in the road more.
