Gif - (click to play) The reversing lights also work. I may add more detail into this with a texture at some point. But that point isn't today. Brake rotors are not done, but looking a lot better than before.
At low speeds you are at the mercy of mechanical grip. So I guess your main options outside of changing the tyre is trying to maximise the contact patch of the tyre. That can be done through suspension geometry, camber of course being a big one, but also castor, since as you steer, your camber will change. Your Ackerman geometry could also be worth looking at. Since you can run parallel steering, Ackerman steering, or anti-Ackerman steering. They all have different trade-offs. You could also try adjusting your scrub radius on the tyres to be more central. Its unlikely to help with overall grip mid corner, but it could give extra grip while steering angle is being changed (more of the tyre slipping less). But honestly, from your video it looks like you are already doing pretty well for grip. Since you aren't struggling with the car, I will also assume that the balance is pretty good too. But maybe that's just you being very smooth with the car? idk.
Just a fun lap with the "Race Pro" model of R20. Xbone controller used, hopefully I should be fit and well enough to do some proper testing with the steering wheel soon . The car now runs less negative rear camber to improve acceleration and provide a better contact patch for corners. When they said "lift over crests", I'm not sure *that* was what they had in mind (0:52).
'xbone controller used' thats the greatest name for an Xbox controller i have ever heard seriously though, looks great (and sounds great too!)
