    Does anyone know of any modifications to made the ride firmer?

    For anyone who has lowered their car, have you noticed any difference in the firmness?

    Pump up the air in tires to +5 psi over recommended... and you now have a cheap firmer ride, enjoy!

    Ride firmness is more about shocks. I do not know if there are aftermarket options.

    I think my air suspension is too firm. I'd like it to be softer, more like a Lexus.

    What rims is everyone using? Tires are a critical part of suspension.
    21" rides firmer than 19", even tire choice will have some impact.

    I believe the ride gets softer when you lower the air suspension.

    It is to a degree, though it might make the tires wear poorly.

    Worse wear, more likely to lose traction and does nothing for roll through corners.

    Roll in the corners???

    First make sure you have the sport sway bars and the car is the right height when set to low.

    You are grossly over generalizing about what 5psi higher will do. 5psi is not going to cause those issues. Going to have to get more carried away adding pressure than that to cause those issues.

    The stock pressure is what they feel was the best all round compromise for a lot of factors, 5psi is going to shift the balance they chose, not stop the tire from functioning. Would probably hurt snow grip, but reduce what little sidewall roll there is cornering. 5000lbs cornering hard is going to roll the tire more than you expect.

    I'll start experimenting with different pressures a couple PSI at a time.

    It definitely goes low. And the sway bars look pretty beefy to me.

    Do you not experience any roll?

    Go Karts have more body roll than Nicki.
    Could you put your car description in your signature? Makes things much easier.

    Nicki is noteably faster and flatter than this guy.

    The late 2014, early 2015 P85Ds had a sportier set of suspension dampers. You could, in theory get a set of those, but I'm sure those would be touh to come by.

    If your car has more body roll than in the video something is wrong. Have someone take a video of you taking a hard corner after putting the car on low suspension (set the speed limit to always then take the car up to 50 MPH to be sure). Either your perception is off or you need a trip to the SC. The ride height may be out of calibration.

    So I tried your +5 psi but that was definitely too much. I'm now running at 45 psi and it has stopped 75% of the body roll I was experiencing. I guess the weight just put more pressure on the tires.
