There were two tools that came with the car that I have (2005 996 C4S). After some research on line, I determined that they are called coil over or suspension wrenches. Can someone advise me when to use them or how to use them. Third option, toss them in the trash... Just kidding.

Thank you in advance.

 

seems like the previous owner installed some after market coil overs, the wrenches are just if you want to adjust the ride height of the car easy enough to do but keep in mind that it will need to be re-alligned after doing so.

If they are blue and silver coilovers you likely have Billsteins PSS9s or PSS10s, very common, and very good suspension.
