There either needs to be car/chassis spec lines for everyone or for no one... Singling out specific makes/models like the Miata/F-Civics is ridiculous. All that will happen is the cars get lead trophies/restrictors to the point of no longer being competitive, then someone will find the next fastest thing. After a year of winning, that car will magically get its own spec line. And so on and so forth.

Having the new Civics weigh more than a VW of the same displacement because Honda actually took the time to engineer a decent strut-based front suspension for the car? What is the deciding factor here? Camber-curve? What qualifies the Honda F-series struts as too-good?

I thought the whole point of finally having a weight/displacement class was to let the cream rise to the top?
