    Hey everyone!

    Long-time lurker, first post here. I'm finally pulling the trigger on a motion sim build and wanted to get some feedback before committing to anything.

    I've landed on the SFX-150 as my base. The extra 50mm over the SFX-100 seems like a no-brainer at this point same build, marginal cost difference, and noticeably better on tracks with real elevation changes. Happy to be told I'm wrong though!

    The idea is to build it in phases rather than going all-in at once:

    Phase 1 — Standard SFX-150 (4 actuators, servo + ballscrews). I'm planning to go Thanos AMC from the start rather than the Arduino route, mainly for SimRacing Studio and motion compensation in VR.

    Phase 2 — Add a traction loss / yaw axis. Haven't settled on the best approach yet — dedicated 5th actuator on a pivot plate seems most common but I'd love to hear what's actually worked for people.

    Phase 3 — Layer on top: G-Seat, active belt tensioner, tactile, maybe wind sim. The idea is to not ask the SFX to do everything and let each device handle what it's good at.

    A few things I'm wondering about:
    1. Is SFX-150 still the go-to DIY choice in 2026 for ~1500-3000€, or has something better come along?
    2. Cleanest way to add traction loss to an SFX build?
    3. SFX + G-Seat + belts + tactile — does this combo make sense or is there redundancy I'm not seeing?
    4. Any gotchas with Thanos + SimRacing Studio, especially with a Direct Drive wheel and EMI?
    Thanks in advance, excited to finally be at this stage!
