Suspension Geometry - Part 1 (Camber, Toe, Caster, KPI, Scrub Radius)

Obviously the statements in this video are extremely General and don't go into technical info such as Tire design & dynamics that require various camber alignment to optimize Tire performance.. .

What they said. Yup. Now I have a question. Nobody is talking about the effect camber has on the contact patch relative to steering pull and toe effect in combination. If I have negative camber and 0 toe on one side of the front, but positive camber and 0 toe on the other, which way does the car pull, and why? What tricks can be used in equally cambered axles, like toe adjustment, can be made to cancel the contact patch squirm/pull from camber? Meaning: With a modest amount of negative camber that cannot be adjusted (some car companies) what amount of toe is used to compensate for the contact patch deformation, if any?
I have an '04 Acura TL that my book says has fixed camber all the way around. The rear is noticeable when viewed from front or rear. Is the amount of toe I am seeing there to compensate for that camber, or is it merely to mitigate terminal oversteer? The car is pretty nimble but not nearly as much as my brother's Ford Focus. That thing is a gymnast!

Too much trouble. I think ill just keep it stock

Finally I can learn in an easy to understand way this stuff! Super impressive!

These videos are very useful. I am designing my own suspension system for a single seater and your videos have helped a lot. Could you tell me which software you use to show the changes in the angles in bump/droop and steer? Thanks.

I failed geometry once and i felt guilty about it now i think it's my teacher's fault 😂

best explanation on the internet

Excellent explanation, well done 👍

excelent video

poo

Yeah ! Great diagrams and explanations. I just went to a motorcycle meeting, and I have a background in cycling. I owned a few suspension bikes, and could not get them working properly. I previously decided to invest in a really good BMX, that's all.
But, looking at the motorcycles. It was odd to see. Large rear tyres, tyres with an odd shape, and weird orientation of the springs.
I read today motorcycles have 57 x more accidents than cars !
Yet, they're a lot cheaper. I might save money through investing in some skill hopefully.

Goat no cap 🚫🚫🧢🧢

The best 'why apply camber' explaination I've had so far

Hey I have a Clio 172 RS and it tends to understeer more with spacers.... I really don't know how it relates on an FWD small hatch, front heavy, scrub radius don't effect cornering directly does it?

Amazing in depth video! What software is this?

what software is this?

Excellent tutorial.

CAYUGA! Thanks for a great explanation!

What is that software that you use to animate suspension?

I'm trying to figure out what I need to adjust to correct the steering and suspension geometry after having to add 16mm of positive offset to both wheels (the fronts needed spacers for the brake calipers and the rears came with an incorrect neutral offset and I paid too much to get them both made again!).

didn't you just show the same for both camber and toe!

I like how im watching this as im about to build a gasser with a front straight axle syspension desighn from the 1800s

Amazingly informative, this is helping so much with trying to build my own car!

Stunning work on this video! Great knowledge base and graphics to demonstrate the concepts!

my brain hurts

Ok so negative is usually better for anything to do with suspension

Edit: except caster :)

Where did you get the footage of the guy driving in india?

This is amazing and super informative! 😍👍

can you do a video ( or do you know of a video ) that goes over how to setup a car ?

ex : if your car is a FR layout and has a balanced handling characteristics and you want to add more under / over steer etc ?

like how would the car react if you added more dampening to the coilovers in the front vs the rear and vice versa. ( leaving the front where its at and only adjusting the rear and vice versa vs front going full soft while going full still in rear and vice versa etc )

i cant seem to find any videos discussing this topic ( and i know it varies platform to platform ) but just in a general sense.

maybe FF vs FR vs MR vs AWD etc

like , if you did one setup change on FF layout it would be complete opposite reaction if you did same setup changes on FR etc

Its the best video that I have watched abt the suspension geometry. Thanks a lot.

In respect to KPI and camber, will the inside tyre gain negative camber and outside one positive? @XF Motorsports

what a shame for me , i dont understand english too well to can take the meaning of the vid ,😭 , from canarias .

Thank u so much, so we’ll explained

Ohhh thankkkk u for splitting it into two different videos. A single video would’ve been an overwhelming amount of information

Such a great video thank you !

good stuff really thorough.

Great Wideo Ghandi 😂

Were you using blender to do this? Just curious.

king-pins r still in use as is rear whell drive,so this vid is a fail...

Complicated engineering behind simple looking things.

What software are you using?

Really please actually try to spit out a VEEEEE sound. Last I checked there's no English language word that is "wertical" please try harder 🧐😐😙

Why KPI induces a lifting force ?

Awesome explanations!

This video helped so much, thank you. The shopping cart example was amazing, and I know know why more positive caster can lead to more negative camber when cornering!

what is that you are using for the analysis?
Thanks in advance

Amazing video. You're incredibly knowledgeable!
