    We are waiting on our custom set of BCs to arrive. I bumped up the rates and valving to 6K Fr and 4K Rr. I was thinking about 5K rears but we'll try this first. BC standard rates are 5K/3K. A bit light in the rear.

    We are putting on the BCs today - upgraded the valving and spring rates to match our chassis. For now this is just an educated guess. The rebound on the stock shocks is horrific as the car tends to come up way too quickly and bobble in high speed sweepers. I'm hoping with better rebound control it will feel more secure.

    These coilovers will be on sale during our black friday sale (starting at midnight).

    Stock height, measured to the centerline of the wheel arch is
    24 3/4 Front , 24 7/8 Rear

    The install was just as easy as the brake install - very straightforward. You'll need a 18mm, 15mm, 10mm sockets and 13mm wrench (angled). It also helps to have an open socket and 6mm hex (see pic) for the sway bar end link. Set aside about an hour and a half or so. You can also use a jack to keep the rear beam in position while you remove the 15mm lower shock bolts. The rest is total cake.




    The BCs are slotted in the front so you can get up to -2.8 deg of camber, right out of the box. Camber plates are not provided since no clearance exists on the strut mount by the firewall. I set the alignment for -1.15 when I am in the car. The alignment I posted is unladen, the camber changes with a driver, going positive on the left, negative on the right when he's in the car. I set the toe at 1/8th toe in for more stability. The rear beam is fixed and it actually ok for a beam. I will beam the beam later for more rear camber, probably -1.7 for the track - and change the front camber to -2.5. The more front camber you run, you lose braking force and straighline grip.
    The rear toe should probably be around -.2 for 40 numbers total toe in. Front caster is actually pretty bad ass at 3.8 degrees for a FWD.

    Its wet outside so I cant push it - but the ride and comfort is a huge improvement over stock. No longer does the car exhibit huge rebound forces (jouncing / bobbing up and down) over expansion joints. In stock form it felt like the spring rates were not matched for the slow speed shock settings, with the springs overpowering the valving. The Fiesta would also bite in a corner then lose its set, then bite again (bobbing). From the limited drive with the BCs, the car feels more balanced, no longer overly sprung. It a good increase in comfort with smoother transitions. Much like taking the edge off while gaining confidence in the chassis. There is no increase in bump steer. Weight drops 6.4lbs over the stock suspension.

    I sent the shock ride height measurements and spring rates 6k/4K to BC Racing so each set will look and ride just like the prototype set I spec'd out. I set the ride height at a 7/8 drop in the rear, 1" drop in the front. There is plenty of room to slam the car but thats not my style.

    As I said, these will be on sale on our site for Black Friday. Or you can grab them from another vendor. Give BC a couple weeks to get these settings in their system if ordering elsewhere. Otherwise your set we ship to you will be spec'd out to our settings. www.2j-racing.com

    All in all, an excellent upgrade and I am loving the ride and handling.

    one K is how many lb/in ? The spring rates in the 2014 FIESTA ST Supplement are listed as 30 N/mm (171 lb/in) front and 25 N/mm (143 lb/in) rear.

    We've sold about 70 sets and never had a warranty issue from our customers (FYI)/ BC is 1yr full. Their warranty is listed clearly on their site.
