nah you wont damage anything. i've ran them for over 2 years now. i think you were just used to having shit ones on! lol. They are abit harsh but i love mine. They instantly make you feel more connected to the car, they are a performance upgrade dont forget

if you can't live with them the escort diesel ones are supposed to be harder, but i dont know personally. Good luck finding a set though, they are getting rare too.
