Personally, I really like the wood kit. It is made really well in terms of fit and quality. It gives the car a more classy look. If that's what you want, then go for it. The carbon fiber is more of a sportier look. As for colours, the wood goes really well with the tan interior. The carbon fiber will be a less noticeable change since it is greyish. You also have to be mindful of the quality of the kit. The fit will be the same everywhere because its done by computer, but the quality of the pieces (the appearance) will vary from place to place. This is especially true of carbon fiber kits. So caveat emptor (buyer beware).
