What is the best way to increase the speed of my Camry Solara without affecting factory warranty?

This topic kind of opens a can of worms but if just acceleration is what you are looking for you can go with a smaller wheel /tire combo in affect changing the final drive with out changing any gears or diff. If speed around corners is what you are looking for the list is endless, but a simple alignment change (more aggressive) would yield great results, also stickier tires. Just my 2 cents.

Thanks for your response Kyle. You are right regarding the can of worms... Basically I'm looking for recommendations in terms of racing parts like Header, Turbocharge, etc. The point here is that is difficult to find racing parts for this kind of car (Solara 2006 V6). By the way, forget about the factory warranty....
