Oh well..... was at my friends house and needing to turn around so I gently went up someones drive way and again gently came down and I heard this bang came down the driveway and the passenger side bumper was ripped out......i looked at the drive way and didn't see anything that can cause this. All I can think of is when I was coming down of the curb to the street the nose of the car dipped to shallow and hit the pavement.

Does this happen alot to Mtech bumpers I never had this issue with my M5 bumper...just curious....either way it "Sucks ASS".

you must have approached the drive form directly straight ahead, and both wheels dipped into the low spot...probably the curb.
thats why its good practice to enter and exit drives and all approaches at an angle.
