Just got my IS250 and had a quick noob question. I wanna lower my car and wanted to do so with some eibach springs. My question is can i keep my stock struts or will they blow out or should i upgrade struts? If i install spring do I have to get my car aligned? Thanks

 

First, you have shocks, not struts.

Second, they'll be fine as that's a pretty small drop... they'll wear out marginally faster than otherwise but not next week or anything

Third, you should always get the car aligned if you change something in the suspension like that
