If I replace my stock bumper on my 04 with a T-Cam bull bar that weights 45 kilos 99lbs no winch, should I expect the stock torsion bars to sag a bit? and if so can the stock torsion bars be safely adjusted to compensate, bring it back to stock height. From doing a search it sounds like I could, however most of the posts never mention the specific weight of the bumpers they are adding. Does anyone know what a stock bumper weights? I am guessing at least 20lbs so I wouldn't think a difference of 80lbs would be that big a difference. Here is a pic of the bar in Questionhttp://lc100.toyota.com.au/toyota/vehicle/Content/0,4664,2001_704,00.html
