I have purchase a Group 4 suspension. Can I reused the original bolts and self locking nuts when I install the coil overs?

The subaru manual states that a new self locking nut is to be used when replacing the struts.

 

Which nuts and bolts are they? If you mean the ones that hold the strut bottom to the hub, you can reuse them. You can also reuse the top mount nuts as well.

 

I always renew locking nuts of all types. However the "official" line is that if you can't spin the fastener fully on by hand you can reuse. However with the distorted thread stiffnuts I would advise renewal.

 

the three bolts around the strut top and the two bolts at the bottom of the strut

 

Yes, you can reuse the three top ones as well!

 

Thank you
