are buying used 918 valve spring with abotu 3k miles be bad idea?

 

Personally, I don't buy used valve springs. Their cost relative to potential damage is just too high. However, if you know the car they came from and the conditions under which they were run, and the deal is excellent, then that might be worth considering.

 

i htink i just buy the patriot gold kit its only like 240. but it be a over kill my car lift is only 588/574 for now at least unless i do go bigger

 

The other option is to just buy the 918's new if those are what you want, you can get them for $160 brand new.
