Well we already have dedicated categorized sections for just about anything that might have been done to a car.

Scroll down the home page to see them.

These cover all models for a specific area of the car. Engines, Suspension, Audio, Interior, Exterior......

Your best bet would be to be Model specific within a forum, then enthusiasts of your particular model will be more likely to follow things appertaining to their car and find things via search engines.

Create a thread, give it a catchy title, post about your modifications and see where it goes.
