| with lowering springs i would recommend getting new shocks just because you might as well do them while your strut assymbly is out, but you dont absolutely have to depending on how low you want to go, with the m3 springs if they lower it at all it wont be much, and again you might as well put in new shocks while you have your strut apart, and your car doesnt way that much less than an m3 the motor isnt necessarily smaller, maybe 30 pounds engine wise, and the M has a body kit but that isnt enough weight to noticably change the ride height |
