Calipers are wilwood part number 120-6985. Also included are TCE brackets to install on 2g rear hub, and some pressure adjusters that TCE placed on the brake hose input line. You may want to use those or have your own front-rear brake bias adjuster. There are like-new pads already installed.

I believe this is essentially the current TCE Performance "drag kit" for the 2g, minus the rotors and lines: www.tceperformanceproducts.com/eclipse-all-years/kits-15/

These are SUPER LIGHT.

That kit sells for $769 + shipping from TCE. Will sell for $300. You just need to find rotors.

EDIT for clarity:

Nah, this doesn't appear to be analogous to the drag kit after reading more on TCE's website and talking to Todd. Main reason is - we all want to keep our hand brake, right? These came from an early version of TCE's rear brake setup for 2gs. You will have to source two .350 solid, non vented 12.2 rotors from TCE to keep hand brake functional with the parking brake hat/drum while using the included brackets.

These are SUPER LIGHT. I have the later version big brake kit from TCE and I LOVE it. I suggest getting their front setup and then you can do the back with these.
