I'm replacing my stock springs with H&R lowering springs. I've got the front right tire off and I don't seem to have the tool required to move forward.

What size/type tool is in the picture where the black arrow is pointing?

 

It's a internal Torx, I don't know the size, but you can just buy a good set. What ever it's size treat it as a one time to get it right issues, meaning use the right size and be square and fully seated in the bolt before you try to torque or UN torque it.

 

As advised/discussed on another forum it's a T60.
