I am considering substantial performance upgrades to my TL. This is my first aftermarket tweak job and would like some advice. I currently reside in California, so i must consider upgrades that are CARB certified. I am looking at tire/wheel changes to 225/235 40/45 18" wheels, Cold Air Intake, Sway Bars, Performance springs or Coilovers (this is a big ? as Ive heard that coilovers can definitly add better performance but dont last very long 10-30k miles before they start rubbing metel to metel and start the "bounce" effect). The main Question I have is who to go with? I have visited ALOT of websites and many dont have the 2004 TL listed or the year 2004 for that matter. Can I get some advice from the heavy tweakers please money isnt really a factor since my dealer is adding whatever my cost is to my financing.
Thanks
