If you are familiar with SCCA rules, I run the Miata against earlier 1.6 Miatas and Honda CRX's. In autocross weight and the ability to get a good handling car are everything. Now my current problem is the 1.8 Miata I have is about 100 lbs heavier than the 1.6 Miata and even heavier than the CRX. I am also only making about as much power as the CRX. Here is the big problem, with the 1.8 liter car I am forced to run an open rear differential (no LSD). The 1.6 Miata has a vicious limited slip available within the rules. The CRX has an open diff but the drivetrain is putting weight over the drive wheels. Basically my car is an underdog. The Crossfire is an unknown as no one has run them with race tires because the race tires just became available in the proper size. Remember this is autocross, not a track event.
