No matter the suspension lift, you can still only fit 33's. So lifting it 2-3" will not allow for larger tires.

1. A body lift does just what it says. It lifts the body (and only the body). AC currently makes a 3" body lift for the new X's. The reason to lift just the body is to allow bigger tires. I am not sure what will fir with the 3" body lift of the new X. It's been said a fe times that with the new X's you don't want to go over 33's because of the weak axles.

2. Learn and get a job. Cars are not cheap and the more you can do yourself the better off you are.

3. Spacers drop down your existing front shock shocks. They seem to cause a problem with the upper control arm hitting the shock mount. Longer coils just extend the shocks to their max length. The only downside I can see to this is possibly premature wear on the shocks. Shackles are for the rear leaf springs. This drops the back side of the springs down and give you lift. It also give the wheel more room to travel (given you are not limited by your rear shocks). Add a Leaf is for the rear. It adds an additional leaf to the spring pack. This leaf is usually arched more than the stock and there for lifts the rear end. It also causes a firmer ride.

4. That is personal preference between Calmini and Daystar. Then it's personal theory between the rest. I have the AC lift and like it. If I had the money and they would release it, I think the 5" SLR is the best setup, but it's also slated to be $3500+.

5. All lifts will require an alignment. This when you take it to the shop (Firestone had lifetime alignement) and they adjust the front tires so they are straight again. When you lift the angle of the tires get thrown off. There are three angles to adjust (Camber, Caster and Tow-in/Tow-out).

6. Pick one, buy it, look here on XOC for help on how to put it on. If you pick the Calmini spacer lift or the Daystar lift you can do everything with just a few simple hand tools. If you choose the AC lift you will want to take it to a shop and have them put the springs on (but you can do everything eles with the same tools as the other lift). If you wait for the SLR or Calmini 5" lift. You might want to ask someone to come come over and help you as it'll be quite a project.
