    And here's our brand new Steel City Racing Logo. We've integrated this into the wrap and may also make a few shirts for the pit crew and team.

    For Navigation, our team did a ton of research ultimately decided to go with LeadNav. Their software seems to really be taking off and it was nice to see how portable and versatile the setup is.

    We'll be using LeadNav's app in conjunction with an iPad Air 2 (64GB Wifi + Cellular) per LeadNav's guidance. We installed a screen protector and put the iPad Air 2 in a LifeProof case for added protection during the race.

    We'll use Ram Mounts to secure it to the cage at the A Pillar or Windshield bar for the Co-Driver. We also added the optional SkyPro xGPS160 receive to great boost our GPS signal.

    There should be more "fabrication oriented" updates with pics coming next week. In the interim, we took full advantage of Black Friday sale and picked up all of our safety gear and the last few comms items we are going to need.

    Pre-Wired Impact Helmets:

    Head & Neck Restraints, Alpinestars Gloves, Sand Skirts, Final Comms Cables:

    Alpinestars Racing Suits:

    Rugged Radios Handheld - One for the Co-Driver when out of the car and one for close-range communication at the pits:

    All in compliance with the new Ultra4 Rules and recent changes.

    Speaking of the rules, Air Bumps are now allowed in 4600!!! I guess they felt back surgery after races isn't popular for the 4600 class. Thank you Ultra4 and the 2018 4600 Drivers for voting Air Bumps in for our class.

    I'm also excited to announce that we'll be sharing a Crew Chief, Pit Operations, and Pit Location with [MENTION=8568]RustyNailJustin[/MENTION] and Team 4619. Justin has been a huge source of advice and wisdom for me since Day 1 of this build and we're honored to be side-by-side with him and his 4619 team at KOH 2019. We'll be pitting somewhere outside the high-dollar, main pit area. :)

    My co-driver for 4600 is a Professional Firefighter and EMT, so he, Justin, and the Pit Crew will fit like a glove!

    Also, while Black Friday was going on, we also snagged a great deal on a Large RV for KOH week through Cruise America:
    [​IMG]

    Probably not the best RV, but certainly the best value we could find for the week by far.

    Finally, we locked down our race number for KOH. We'll be car 4602 for 4600 and 4400. I have 2 awesome girls and 2 awesome chocolate labs, so great things seem to come in 2's for me.

    Brand new pics of our Gen II Front RCV Ultimate IFS Axle Set. We'll be the first 4th Gen 4Runner to run RCV's Gen II axles. The Gen II set has a ton of enhancements over Gen I.

    They are massive and rated for 40's with a Lifetime Warranty. RCV was the only choice for our KOH build and we were really excited when they agreed to allow us to run the first production set of Gen II shafts on our 4602 KOH bound IFS 4Runner.

    These fit our 4th Gen 4Runner, but also fit Toyota FJ Cruiser ('07-'14), 4th and 5th Gen 4Runners ('03-Present) & Tacoma ('05-Present).

    A number of folks have asked for Gen I and Gen II specs for the RCVs, so I wanted to pass the information below along from RCV's lead engineers.

    As noted above, we're running the first set of not-yet-released Gen IIs at KOH:

    Gen I Toyota axles had the following attributes:
    Spherical Dana 60 sized outer CV joint (grease maintenance required)
    Spherical outer CV boot
    30 spline Porsche 930 inner CV joint capable of 28 degrees of angle (Dana 44 sized)
    Dana 44 sized 30 spline to Dana 60 sized 35 spline 4340 center shaft

    Gen II Toyota axles have the following attributes:
    Dana 60 sized outer CV joint (no maintenance required)
    Traditional CV boots on both ends
    Dana 60 sized inner double offset CV joint capable of 30 degrees of angle
    Dana 60 sized 35 spline to Dana 60 sized 35 spline 300M center shaft

    It's going to be a good time and crazy adventure.
    Lots of memories to be made and live life with a bit of Jeopardy.

    Should fit the GX or 120/150 series as well, no?

    Everyone seems to love LeadNav software, but I've had a few questions about the iPad connections. Here's what we are using:
    [​IMG]

    LifeProof Audio Connection (I have to pull hard to get this out):
    [​IMG]

    LeadNav Ruggedized Power Cord:

    GPS is connected via Bluetooth. We'll be heat shrinking any connections to these wires. Hopefully these connections will prove strong enough for KOH conditions in testing.

    I think so, but am not 100% sure. I'd check with @RCV PERFORMANCE first.

    With your timeline, how do you “take it easy” for the break-in miles of the gears?

    He is going to have to shakedown a bunch and shock tune. Tuning is a good time to get gears through a few heat cycles.

    not to worry Justin, I think your rear axle will be ready and you will make the starting line in time! Good luck out there and stay safe. I will be watching from the couch this year.
