i have the bmr lowering kit. only installed the springs and adj panhard so far( gonna wait to get lca's before i do the brackets) rides great, handles better then stock. when you get into the turns you really feel the difference. as far as the kit goes, i didnt use teh camber bolts, mine went back to spec without them and i opted not to use the supplied spring moutns for the front of the car. they say they are a one time use but i saw no reason to replace mine, maybe when i change out my struts and shocks i put them in. best part of teh kit for me was the adj panhard. i have 285's out back and you can really see the offset once lowered. the bar fixed everything up and its very easy to adj while just lying on your back under the car( well assuming you fit, as i barely did but im on the small side,) butin my opinion buy the kit, great value for the money i think.
