i lowered mine 2" adjustable rear. car corners great,BUT: you will go thru tires often and LA streets will drive you nuts cuz it sucks, however the car handling is amazing as long as you leave the HICAS system in tact. Also lowering the car will cancel your electronic suspensiton that if you have a Twin Turbo. :Obviously ever car and every setup is unique, but what is a good starting point for a car that will spend most its time on road courses. I will dial things in eventually through testing, corner balancing, and alignment, but I would like to know where to start. Is stock ride height close to optimal like some say?
