Driving low rider it always a problem man, but it shouldnt be much to your car. Must drive slow, especially on rough road.
low your car prolly the best option for me to avoid speeding

this is pic of my old work van back 5 years ago as an example, with just 4 finger ground clearance, i used standard shocks (i didnt use proper shocks, prolly worse than your car).
its my daily drive from syd to country side, roughly 800 km each day. it was pretty much travel on gravel road
i never had a problem ever since i was driving max 100km/h on smooth road and 60km/h on gravel road
