i have the bushings and 1 1/5 lowered with eibach springs, its a real bitch having to avoid speed bumps. how much will i be looking at spending on the IRS brace, is it a pain to install? ill probably wait to get new tires til i burn the ones on it off . i have always been good about if i start getting wheel hop to let off immediatly, will it be very noticable right away if i have done damage to the rear end?
