OE LSD vs. Aftermarket LSD: All of the target vehicles are available with Limited Slip Differentials (or electronic equivalents) as standard equipment in some optional configuration.

That said, not all factory LSDs are equal and an argument can be made that, for reasons of parity, aftermarket parts should be allowed. 聽聽聽聽2. Inclusion of 2006-present Mazda MX-5: Is this car appropriate given the desired performance level of the class?
