Spring install fail
 

Hey guys I recently purchased some H&R springs for my 370z and the fronts went in fine but the rear was questionable. One side of the rear springs has a much larger diameter then the other as shown in the pictures. So I decided to put the smaller side up and now the spring does not seat properly with top rubber hat.... Either I put it in backwards or I have to adjust the tophat like someone on here mentioned...Attachment 146289

You didn't put the front on the back did you?

So what did you do install the front springs on the back? :shakes head: Send them back to however you purchased them from and do it right the first time and get coilovers. You are the first person I have ever heard have issues with the H&R springs. Please research the brakes and suspension part of this forum before doing any modifying of your suspension on your Z you will thank yourself later.

Nope the front already came on OEM struts... I did not have to put the spring on there, the person sold me the all 4 struts with the front springs installed on the struts I know for a fact that is the rear spring.

There has been another person here that said his did not seat with the tophat properly either and he had to take it apart and rotate it.

What is the model number on those springs? Should be 53075. Those don't look like the correct ones.
