In the long run yes...I had coilovers in my Silvia for a couple of years and there are stress fractures all over my bodykit and thats just an example. I also kept on blowing my headlight globes and it was only on my 4-5th replacement that I was told that because my coilovers were so hard, it kept on shattering the filaments in the globes. I've since replaced the coilovers with normal sports suspension. I enjoy driving it again Coilovers were never really designed for everyday on road driving. There is a price to pay I guess.
