Upgraded my B7 to 18" alloys last week and also got my indy to fit H&R lowering springs - lowered both ends by 35mm. Everything was fine until today when i foolishly decided to travel on pothole riddled remote roads in the western highlands...i tried to be as careful as i could but couldn't avoid going over a few deep potholes Now i hear this faint rumble coming from underneath the car when driving between 20-50 mph...the rumble sounds like when you drive over rough tarmac. I also had brand new tyres fitted last week so the noise might be tyre related but i have i feeling i may have damaged the springs. Any ideas what could be wrong?
