Hello, everyone

Looking at one 2007 Porsche 997 Turbo, manual, Sportec tuning (547hp/800Nm).
It sits on HRE P43 20" rims with 235/30 fronts and 325/25 rears, and has H&R springs installed.

Does it mean extremely harsch ride and lots of scraping compared to standard springs and 19" 235 + 305/35?

Thanks in advance!

Drive it and see for yourself

The 20" wheels with "shorter" sidewalls will lead to some additional harshness. Do the H&R springs lower the car or are they stiffer than stock, or both? If they lower the car, then yes, expect to be more careful in driveways and speed bumps. If stiffer, then expect some additional harshness.

Ride it and see, but my guess is that it will be much stiffer than stock and with the set-up you describe, I bet the car bops too (i.e., you hit a bump and car rocks forward/backward). Do you know what kind of anti-roll bars are on the car?

Thank you all, guys.
I drove the car for half hour on country roads. Well, it is stiff but did not seem to be excessively stiff. I could handle this I think.
No, have no idea what kind of H&R springs are on this car. The nose is 120mm from the ground. I measured on stock car, there is it 140mm or so, so I assume this is a 20mm drop springs.

Could this kind of setup destroy the suspension? (Well, the car rolled on this setup and wheels for 39k miles so far).
