Its also easy if you get the WW RS kit... since its a lip kit. I had my body shop paint it, then me and my friends did the install.
However if you get anything other then a lip kit... I suggest takeing it to the body shop since extra sending may be required. Especially when it comes to fiber glass kits.... those thing rarely come with a perfect fit. They almost all the time have to be modified. Plus dont forget.. you gonna need to paint it anyway .. so might as well have them do it.
As far as ordering... shipping to business address is cheaper... but not all the time. Ask the company who you getting the kit from if they will do a lesser price on business addy then on residential. Mine was the same to business or residential.. SO i shipped it to my house... I LOVE GETTING CAR PARTS IN THE MAIL
