You won't get flamed in the 4.6 etc forums if you post about apperance there. I have posted questions there before and nobody mentioned anything about performance parts.

Simply state you want an opinion about a mod. The horsepower guys like their cars to look good too. In fact, you might even give some people some ideas when you post. If things are really as seperated as you say, I would love to get some ideas from guys that haven't been posting in the engine specific sections.

I didn't realise there were so many people talking in the apperance forum, I thought it was a dead forum. I do not think I was the only one only posting in 4.6/5.0 on a regular basis. Give it a try. If nothing else more people will respond to your posts.
