I love my 03 Rubicon, Brandon if you want a lil more oomph, k&n cold air kit and a throttle body spacer, takes about half an hour to put both on, huge difference. then you can use a hyper-tech programmer and change a couple things to make it even more responsive, and get better mileage to boot.
I've looked into those exact mods, but I haven't heard anyone tell me they made a noticeable difference? There's also a turbo exhaust out there that I've heard bumps it up pretty well.
On the highways they are similar to driving a Cat actually. They wander a little just like you'd expect with bigger tires. On the factory wheels/tires they don't however. The ONLY thing that could noticeably have been improved is about 50 or so more HP from the factory. It's not bad though, and it IS still a Jeep, so you can't expect Supercar type performance.....yet. :sifone:
