The hotly contested GTLM class—the top GT class in American endurance racing—makes its triumphant return to Lime Rock Park this afternoon. Here’s a Porsche blasting through the Connecticut woods, as it should be. Today’s race starts at 3:00 p.m. ET on Fox.

I’d rather have a Loewy-designed S1, it corners like it’s on rails.

This is an important detail when trying to give your passenger the ole “Hot Seat” when it’s 90+ degrees outside.

You are correct, however, the regs have little to do with emissions. You can’t swap a old dirty rotary for a newer LS if the intake tube is 1" shorter than when it came from factory.
