    I have a new obsession, and it is this tire.

    If there's a company I'm a fanboy of it's Michelin, and these sound like the perfect track tire for my wants. Optimized for long life, fine to drive to/from the track, and onboard temp/pressure monitoring as well as suggestions for pressure changes for better lap times-- in an app I can run on the Avin, on track.

    Fuck yes.

    Ordering.

    Yeah, I need to go through and replace them. Host went down.

    Do the pictures on the first page just not load for anyone else? They aren't showing on my computer or my phone

    Got it, thanks! I bought an Ender 5Plus which works great. I printed the first set in high temp PLA. Going to see how those hold up. Otherwise I have some carbon infused ASA I'm going to give a go.

    Build is looking sick though, kudos.

    I'm curious to hear what made you move away from your custom 3D printed brake ducts. I used your design to print a pair over the winter. How do you like the Hard motorsport kit, specifically the slim low profile ducting component they now have?

    Good progress recently (later than I hoped, but... big undertakings this winter)...

    Installed the final tube of the brake ducting, and confirm it fits without issue in all positions:

    ^ Barry at 3DM is great! Close relationship with Öhlins USA, including a lot of testing work on BMWs for them.

    Ha... more involved question than you might think.

    I found a line barely barrel springs that eibach makes, which they call their extreme travel line. That allowed me to use a shorter spring (6" IIRC) up front, while still having sufficient travel, which puts the perch above the tire at my desired ride height, allowing me to run bigger tires without compromising offsets (lets me run an ET35 front, which allows me to not have stupid camber to fit 285s). So, my front left is an eibach extreme travel 6" "barrel" spring. Eibach 0600.2530.0350.

    Front left was tricky because the extreme travel line only comes in 50 lb increments.... but then I realized that GC sells and extreme travel spring (made by eibach, though they don't use that branding-- but visibly the same thing and I confirmed that they were with GC) in 6" 375 lb. Ground control GC150.64.66.


    Both fronts are either 65mm or 2.5", I forget which (and am pretty sure most spring companies use the same thing here anyway. To fit that on the H&R shock body, I'm using Ohlins spring perches-- same thread pitch, so it's plug and play. Still using the H&R lock ring, because it's free.

    Rear left is a TCK 700 lb beehive from my old TCK coilovers. TCK TKE 360 700 R.

    Right rear is a GC linear 650 lb spring... I think 6"? With some of their cones on the top side, to protect the chassis from the spring.

    Both rears are sitting on the H&R rear ride height adjusters, because they're really nice-- let you adjust the height without taking the spring out, or wheel off, which makes corner balancing way easier.

    Great job and thanks for documenting all of this. I can appreciate the reasoning behind the choices you've made. Looking forward to more reviews of the suspension!
    I had the hybrids before. They're closer to street than monoball in NHV. They're a nice product.

    Mostly I don't think there's a ton of increased precision to be had from the monoballs/hybrids over street plates (as in, it's not hold chassis geometry like control arm monoballs) and they are a significant NHV contributor. So, the trade off didn't seem worth it to me.

    ... and the hybrid TMS camber plates have gotten crazy expensive, once you add the perches and shock adapters (and I sold my previous set with the Ohlins).
