What a great piece of work. Ive spent most of my life around race cars and very few of the 'experts' I've met could make a complex issue seem so simple. Love your work.
Very interesting video, but don't forget that as soon as you get any roll angle, the geometry changes and the roll centre will move all over the place. The roll centre is usually a product of the suspension geometry, not the ride height as such. I found you a few months back for your TVR 3000M videos. In fact I've just bought one myself so I'll be rewatching those again!
great explanation, most videos just don't have the visuals to back it up. Everyone talks about lowering the center of gravity, but never mention the roll center itself dropping and instead of having less roll you gain more without the suspension travel to even handle it 😳
Thank you, there more aspects we could talk about like where do the forces pass through the suspension. For instance when cornering the outer wheels get a specific overall force sideway/down. If break that force into two vectors, we have horizontal and a vertical vector. The horizontal force is always passed to the whishbones to the frame and the vertical force through the coilovers... When the RC is low, the vertical vector ( force) is much bigger then when the RC is higher. on the otherhand , a high RC passes more forces through whishbones and less through the coil overs... lets of stuff we could talk about...
I have 2 cars that are too low from factory. A Porsche and an Alfa Romeo. Both touch the ground unless I enter and leave driveways at a 45 degree angle. There is no way I would lower them any further. Great job 👍
The center of gravity should go up as the car lifts. It appears to be around 200mm in both cases. Case 2 should be higher reducing the effect, though it is still present
Yes in reality it does move if you lower or raise the car in reference to the ground , but not in reference to the RC.. Its the RC that moves, and of course what `i have shown is a static RC. That is in reality also moving while we corner left or right... The way I have shown it, is to keep it simple enough as it is a complex interaction between many forces and parameters
Hi! I find your videos very informative, so thanks for posting them! I race asphalt circle track stuff here in the US, i was curious if you or anyone in the comment section here could recommend any good text books that go over chassis setup or is there any online courses that i should take to gain this valuable knowledge. Thanks for your time!
