Stability was no issue, i have 205 yokos on genuine rims, nerves was an issue :-), RPM was around 5.5 to 6 honestly did not look, there were no issues otherwise, car runs on Helix Ultra i check oil and other stuff it was fine.
It was near Bhera so the road was flat (no downhill), videos on the net maybe of the 2.0 version of the civic which is 10 - 12HP more.
and I do not plan to do it again.
