How To Make My 06 Sport's Feet To Be More Agile?

[M500]

I bought an 06 Sport for my wife almost 2 month now. We loves the car and its quite a different experience then the BMW or Infiniti that we used to drive. The only part that bothers me is the steering respons feel slow and unprecise.

What can I do to make it better?

1) I have a 19" wheel ready to mount at this time as soon as I break in the car.

2) Would a beefier anti-roll bar cure the issue? Is there one available?

I try not to tampper with suspension as that is something my whole family is enjoying right now. Well, except me but I rather to keep everyone happy then just me. Thanks for all of your inputs.

Your 19's will help a lot in that department. I think you should wait and see what happens.
