For sure most people will be biased toward the car they own; its all about proving to everybody that you have the superior car. If you were to post this in the Civic forum, there would be people saying that an Si performs better than a GSR or a Prelude manual (all stock vs stock).
What I tried to do is give some scientific info about the car vs the car in the form of a head to head comparison test, where variables like driver, track conditions are controlled for.
But all that means crap if YOU are racing your car cuz it ultimately boils down to what YOU can do in your car.
