Safety Wire and Rotor Hats

The stock Wilwood rotors have held up well, but really aren’t intended for extended track use.  Earlier this year I upgraded to calipers with steel pistons and no dust boots, so when it came time to replace the rotors, I thought I’d upgrade that as well. The Spec-37 rotor is Wilwood’s Premium Grade, Heavy Wall Casting Rotor suitable for race use.  The street rotors I was using came with round head, Torx Bolts.  I saw a different bolt part number in the instructions, and found instead a bolt kit with drilled heads intended for use with safety wire.

Since I love to buy specialty tools that only serve a specific purpose, I had to get this set of safety wire twisting pliers.

A quick search of the inter-webs turned up this video, which is now one of my all-time favorites.

And a little while later, belt-and-suspenders-level confidence. (Or Red Loctite and Safety Wire.)
