Bilsteins fine on blacktop, but.....
	
	
		Bilsteins may be fine on the bitumen, and indeed mine were. But they self immolated on corrugations.
The first sign of trouble was smoke coming from the engine bay. Both Billies looked very unhappy. With no option other than to press on slowly, it was soon apparent that the Billies had let go and the front of the car was wallowing up and down like a boat.
Before too long the left side Billie had completely disintegrated, and managed to jam itself cross way through the spring. It was jammed against the tyre and the car was going nowhere.
Yes, conditions were extreme, but the shocks were less than a year old and this was their first major trip.
I have changed over to Tough Dog adjustables. They have survived the same trip, which makes them a better shock than the Bilstein, but its too soon to comment about their longevity.
