I'm not so sure. The percentage of performance-related topics we've had is fairly small. Most of the topics are diy and repair issues. You now have 12 different forums in action. How far are you going to break it down?
When I do a repair to the car, or any of my cars for that matter, I always look to see if upgrading is a reasonable option. Let's take brakes for example, if I want to work on my brakes and need advice, or I have upgraded my brakes and want to pass on my experiences with the work, do I post in the Tech section or the Tuning section? I guess if I want all the available information I will now need to look in both.
I think both could be covered under Tech. It is like the vintage Ferrari section, I never look at that. When I log on, I check Ferrari discussion, tech, and driver's lounge. If I have time I will check out the others but generally not. If I happen to see a vintage Ferrari I would post my encounter in the Ferrari section, not the vintage Ferrari section.
You know how when you call the credit card company or the airlines you get a whole menu full of options that lead you to other menus full of options? I hate that. If I want tech info, performance or otherwise, I would like to have one place to go and get it.
