I have a bf tornado and have put 18 x 10 inch wheels on the rear.. The left hand side sticks out more then the right hand one and is really noticeable because of the wide wheels.. Everything under the car all lines up and drives perfect, I've heard that sometimes that the tubs arent aligned properly.. How do u realign the tubs, eg.. How do u get the tub liner out, were are the bolts etc just before I dive in without a clue.. Cheers
