Understeer occurs when the front is heavier If that's the case, lift-off oversteer occurs when the rear is lighter can you explain this teacher?

I had a few questions that i’ve been scratching my head over if you don’t mind me asking. By the way, such a gem of a video! i’ve watched this a million times mainly because the more i watch the more i understand and also because my experience and understanding grows in life. - Why do we not want negative camber or grip in the inside tire because its pushing the opposite way? I think i’m missing something and couldn’t wrap my head around it. - Trailbraking gets more normal force in the front without mass change but lateral load transfer doesn’t have mass change as well with increased normal force. Why are they not both desirable? - Last one’s regarding the stiffness of front or rear axles. If we stiffen front axles, it handles more roll moment and therefore has less available grip. Is it true to shift focus of my thinking on rear axle because it handles less roll moment, it has less load on the tires therefore more grip? i iust couldn’t wrap my head around on why stiffer axles mean less grip. Thank you Professor for making this amazing video and for future videos to come. I eagerly await more and have signed up on your website as well!

Very good job. Most of it was a review for me but i learned a few things in regards to car setup. I am Engineer whom loves physics and math so i found it very enjoyable. My race car experience is a handful of autocross tracks and the Gran Turismo video game. You referenced Carroll Smiths book "Tune to Win" at 53:51. His books (Drive, Tune & Engineer) to Win are excellent too.

1:17:14 "frequency thing was developed for passenger cars it is a transmissivity issue as far as i can tell" It matters like life-death difference in any car on a poorly built road. Humps that align in a sequence that resonate with any of your car's axles in a corner will show you what it's all about. Try some former soviet block country "highway" at big speed but be prepared (have your will written and signed beforehand). There was a police released video on YT from a crash scene in Hungary where two boys in a Huracan filmed their accident. At over 300 kph the car hits the humps (not even in a bend) - they flew off and died.

As someone who already knows a lot of the physics, there were some important insights here that I hadn't ever considered, especially about the transitional stage where you're trail braking and releasing the brake. It had never occurred to me that because the front springs are still compressed as you release the brake, you're still benefiting from the increased front traction and the lack of braking. That's why that instant of release creates such a strong turn-in, and it's really important in off-road racing where understeer is a big problem. Getting the timing of that brake release right is how you get the Scandinavian flick to work as well. I'd love to see an expert discuss the specific issues as they apply to off-road racing. There are a lot of questions I have particularly about spinning tyres and side bite on a loose surface. Contrary to tarmac racing, sliding is much faster on loose surfaces.

(01:06:00 _et seq._ ) For the mention of the desirable characteristics of positive caster angle, you do not mention its effect upon anti-dive configuration. Is this pertinent?
@Andremarziali Жыл бұрын
It is pertinent indeed. I've left a lot out of this lecture, including anti-dive and anti-squat. I know it's nearly 3 years overdue, but I'm still hoping to provide more content at some point to fill in those gaps.
