springs will obviously make your car drive 10x better where as tints will stop you from reverse parking as easily, get you pulled over by the po more often and not stop your car from handling like a 3 legged elephant
so as i am sure you have allready come to a conclusion from above,
GET SPRINGS and shocks if you got the money
bcareful wit insurance tho...(sorry to be old man, had a friend back iin the day who got a new arse torn for it)
