Definitely silver in my opinion...I think it will work real well with the look of those (way to large for the 986) wheels you have there...Lol...of course I jest, I actually like those wheels alot...but again I think the silver will look great.

Grizzly, my vote is to stay consistent with the current crests, which are gold. Now, if you changed the hood crest to silver, I'd say go silver. The steering wheel crest is less of an issue, since this in an interior detail.
