Oh man I just lowered my car with Tanabe df210 about 4 days ago, love it and never had any problems till today. Well i just started to hear a rubbing noise today and it sounded like tire rubbing the inner fender. Thats what i thought it was because it would rub a little only when i do a sharp turn, but it started to do it when im driving straight. wtf so i pull over to look and see that the upper contol arm bolt is a hair from my tire. so i look and feel the other side and its got an 1 1/2 or two inches of space. anyways im probably 2 miles from home and BOOM!!! sounded like a shotgun went off, my tire exploded. btw i was sitting on 235/35/20 tires, so i change the tire with my stocker and there is still is barely any space between my upper control arm and stock wheel & tire. also i've never been in an accident, so what u think happened? imma have to go check it out tomorrow.

 

I think when they bolted it back up they didnt screw one of the bolts in far enough, there should be a bolt with a pin like thing in it.
