Why are suspension settings part of the on-line PP setting?

[MasterGT]

This is a head-scatcher.

An on-line host can set the PP maximum for a lobby, but the new PP system includes suspension values in its calculation.

Why would they care about what ride height a driver uses? Maybe he wants, say, more/less oversteer than other drivers. Why should "driving style" values be part of the "performance" calculation?

Because suspension settings directly affect the "performance" part of Performance Points. It's not just a way to customize the handling of the cars, some configurations are inherently better than others.

A touring car with a 60cm ride height, 10 degrees of positive camber, wonky toe wouldn't be fast. A touring car with a proper set up would be fast.
Suspension set up directly affects performance.

From AST Suspension:

"Ride Height
Ride height adjustments are a very powerful tool affecting the overall behaviour of the car.
Though asymmetrical (left-to-right) ride heights and spring rates are very common in oval
racing, in the vast majority of cases, keeping the car symmetrical is best.
Note: The term used when comparing the front ride-height to the rear ride-height is RAKE.
When the front suspension is set lower than the rear, the car is said to have “Positive Rake”.
Front:
LOWERING the ride height of the front of the car will shift more weight to front, improving
front tyre grip and thus shifting the balance to less UNDERsteer and/or more OVERsteer.
RAISING the ride height of the front will shift weight to the rear, improving the grip of the
tyres at the end of the car and shifting the handling balance toward UNDERsteer.
Rear:
LOWERING the ride height at the rear of the car will shift the weight and grip to the rear.
This shifts the handling balance toward UNDERsteer.
RAISING the ride height at the rear of the car will shift the weight and grip to the front of
the car. This shifts the handling balance toward OVERsteer."

Plus lower, stiffer suspension will obviously improve body roll characteristics and more. Then there's camber and toe to think about. Sometimes the most effective upgrade to a car is a good setup.

You can see how your suspension changes, amongst other things, are affecting the handling performance of your car under the stability and rotational G sections in the left hand section on the car settings sheet. You can even see changes in acceleration performance although it tends to be very minor.

Saying that, certain aspects of the PP system are a little wonky. Sometimes if you make very minor changes to something like the downforce, the PP changes significantly, even though there is no difference to actual performance. You can abuse this/get caught out by it in PP restricted events, as it's possible to find a sweetspot where your PP is reduced but the handling performance of your car is completely unchanged, which then allows you to add more power/reduce weight. Hopefully that's something that PP will pick up on shortly and we'll see some improvements to the system.

Ride height for example makes a huge difference in handling in GT7. And changing anti-roll bars for different "driving styles" doesnt affect PP much.

Ride Height seems to affect Lateral G values heavily. Incresing ride height of high downforce cars decrease their PP drastically.
