With an 04, I would suggest that you add on the front and rear upper mounts/bearing combo as these are infamous for wear and tear.
With the OEM 17's, you will most likely need a 5mm spacer on the fronts, and if you want to go really low, you will need to address the front sway bar by:
- Removing it
- Replace it with an aftermarket one made for aggressive lowering
Let me know if you have any additional questions!
