The differences between sport and non-sport are the struts and the sway bars.

I have been thinking quite a bit about this dilemma for 04 Sport owners. I am going to suggest some things that MIGHT possibly help your ride quality:

1. Switch to a lighter weight 17" wheel and touring all season tire (although that last step will cost you grip and braking effectiveness)

2. Do a big brake upgrade using lighter //M floating rotors and aluminum calipers

3. Go to a smaller sway bar

4. Use a higher grade strut like the Bilsteins.

My thoughts on items 1 and 2 are that if you reduce unsprung weight you should improve ride quality. As to item 3, this should minimize the impact of bumps that are not taken straight on, but it will also diminish handling. Finally item 4 should just help because Bilstein seems to make a better product (this is just anecdotal) than OEM.

Just some thoughts...
