the supension is fully unloaded? that spring looks like it will jiggle around?
thought usually there's a thinner smaller helper spring to keep them in place?
As you can see the wheel was off, and there were no alignment plate bolted to the hub or anything else supporting the upright or hub... so yes it was at full droop.
Helper springs are really only needed if the setup has
- roll stiffness ratio is extreme enough and the turn duration long enough that the unloads one corner enough or lifts a wheel and for long enough a duration
- low spring rates in general and/or low antis such that travel is used up quickly under lat and long accel
- low downforce and so low aero damping and low vertical load over most parts of the track
- low rebound damping force such the wheel even over temporary unloading means lots of droop
- a lot of droop travel on a closed wheel car in order for the wheel and tire, if deep within the wheel arch, to clear the wheel arch when the car is raised, so that wheels can be changed easily in quick pit stops. Need to drop the car after and have springs settle right without damaging anything.
Or if the track is really bumpy and / or curb hopping is required.
Most mid engined racecars making decent downforce like this, don't fit the above. And the tracks they run on are almost always pretty smooth without crazy curbs. Few series' have pit stops.

Jeremy, the single photo shows all kinds of sexy properness lol.. which is why I uploaded it... the damper, the light but super stiff bulkhead, cnc machined bits all serialized, quick-adjustable ARB, proper connections and insulation, beefy adjustable tubular control arms, clean brake wear , ducting, lightweight but very durable kevlar wheel well..
Don't wait for SG track.. it might never happen hahah
