Ride Height

For SPB, rules say: "Ride height minimum 90 mm front and rear as measured at front cross of aluminum cross member and front-to-rear braces near rear sway bar."

With that in mind, the smart guys keep saying you definitely do not want to actually go that low. Where the sweet spot is, I'm not sure.

The sweet spot is where aerodynamic drag and suspension performance are optimized.

Set the ride height too high and the car has too much aero drag. Too low and the suspension geometry isn't optimized or might even be on the bump stops and the car doesn't handle/grip as well as it could.

Finding that sweet spot in the middle is an art.

For SPB's, setting the ride height at the specified minimum has been found to compromise suspension performance - this is why guys much smarter than me say not to go this low.

Joe, to get you into the ballpark, my car is set at 12.125" front and 12.50" rear from center of wheel to fender lip.

I have seen other Spec Boxster's set higher and others set lower. Your mileage may vary.
