Loaded question...lol. We all seem to mod a little differently depending on our use or our personal feel for the car. I don't have a problem with the suspension, I just like HP... So, my 5 mods were in this order, 1. a cold air intake of your choice (Dual Needswings for me), 2. a pulley, several choices out there,(code 3 for me), 3. Catch can of your choice,(Needswings for me), 4. A tune from Eurocharged to bring those mods all together, and my last choice would be the wavetrac limited slip rear end...to hold all that HP you just made... All the rest, like intake mods, exhaust mods, suspension mods can come later. I would have included the intakes as well, but not for everybody...as she will make significate HP with the top 4... Good luck, as you will get a lot of different answers....
