Hey guys, I'm seriously considering picking this car up soon. I was wondering if I could get a quick sum up by you guys of what I can and cannot do to it to make it perform better without voiding any warranties? I was looking at better rear sway bars, a front strut stiffener, and maybe long term swapping out some exhaust and intake parts, though if I do that specifically it would be a very much long term upgrade from right now. Any other upgrades that make the car noticeably better without messing up any warranty issues? Thanks!
