Im looking at picking up a roof rack this season but unsure what size to get for the civic.

Question is, will the roof rack from a camry fit onto my car?

I know i need different clips but how do I go about knowing what clips i need?

 

Every roof rack manufacturer has a fitment guide on their website (especially Thule and Yakima). If you need an all-in-one site to find information, try Rackattack.com.
