Hey I just got a set of H&R coilovers and have some questions on the install.
The rear's seam pretty basic but the front's I am confused about since there is a cup that comes with it.
Does the old strut mount of the old struts go on top of this cup?

And also is it safe to reuse one of the old strut nuts because I am missing one of the ones that came with the H&R's

 

Always always use new nuts when you mount your struts, call H&R and they should send you a replacement also they should of come with instructions.

 

I bought them of a member so they did not include instructions.

 

GO TO H&r CORPORATE SITE YOU CAN PROBABLY DOWNLOAD A SET THERE.
