Project EP3 Civic Si, Improving the Brakes with Fastbrakes, Stoptech and Willwood

,

Our 5-lug assembly of the RSX Type-S knuckle and hub is loosely assembled onto the suspension.

The knuckle to strut bolts are tightened and the axle nuts are installed and staked.

The lower ball joint nut is tightened and the cotter pin installed.

The brake caliper mounting bracket is installed and bolted to the knuckle.

Next, the assembled Fastbrakes rotors are installed to the hubs and fastened in place by the Phillips Head mounting screws.

Finally, the Wilwood Dynapro calipers are installed and torqued down.

  1. This is so cool. I’ve been having a blast reading your articles on proper handling and suspension. That, proper Aero and intake/exhaust volumetrics are the Black Magic of Auto Design!
    I’m hoping to get a nice EP3 here in Europe as well. The one with the proper K20A2. 😉

  2. Hi Mike,

    Just want clarity…

    “The piston sizes are 1.62″, 1.12″ and 1.12″ for an overall area of 4.04 square inches. The stock front brakes have a piston area of about 7 square inches, so there is less hydraulic gain in the caliper than stock.”

    When you refer to the Wilwood’s 4.04 square inch area, is that just for one caliper?
    And 7 square inches, you’re referring to the total of the front two?

    Thanks!

  3. Hi Mike, I’ve been enthusiastically reading the transformation of project ep3. And I have to say, I love the direction you guys choose, and on that I’d love to follow with my own ep3. I’ve been able to source some of the suspention ,( swaybare ,tirodends, balljoints exc.) What I am struggling with is the front brake kit. I was able to find the ep3 kit on the fastbrake website, but it lacked some of the parts that I read in the article. It would be awesome to follow the model you guys have made. Any guidance would be greatly appreciated if you have a chance to reply to my message. Thank you.
