Are there any body kits that come prepainted. I just don't want to go through the hassle of paying more money to have it painted and having to wait to get it back.

 

The factory bodykit comes prepainted AKA "Nismo"...you can get it from everythingg35.com or a few other sites...but it only fits 03/04's...not 05

 

The NISMO front bumper for the coupe was unpainted. It has a bit of a white gel-coat on it, but it's not nearly a match for IP. Likewise, I held a pair of the NISMO side-rear diffusers (2pc.) that attach right behind the rear wheels and they were the same.

You could get the OEM spoiler, splash guards and lip-spoiler pre-painted, but not the aftermarket kits. Prep and paint is half the bodykit. It's just going to look like a carppy kit if it's poorly finished or installed... ...then you wasted your money and made your car look bad. Just build the cost of paint into the cost of the bodykit when budgeting.
