A good camera, a good mic, a big whiteboard with tons of natural light, complex ideas in simple terms - man you've got all the parts of an excellent YouTube channel. Very professional and polished right from the start. Reminds me of Engineering Explained with better lighting and less frantic rushing. Hope to see you get famous mate!

Hey great articles Kyle. I was once a top level race-car engineer and you'er bang on the money. Bump steer is a critical element in car dynamics. It's also not well understood in racing circles believe it or not. <br><br>The reason why i chime in here is> Importantly with bump steer on the rear. Make sure it's zero or toes in slightly on bump. Toe out is diabolical. Trust me, I've been there many times on different cars and it was always a disaster. <br><br>PS: Also little known. Beam axles/live axles also have bump steer, mainly in roll.

Watched your video forever ago, and just found it again. I believe the steering system from your Hilux is what's called Pittman arm steering. It's used mainly on trucks with lots of suspension travel

very nice explained , also fast and to the point , at 9.30 i would like to ad something ,( and i am talking racecars now), in a corner when a chassis rolls , we speak of roll steer, in a racecar the akkerman princ. is not (so) important(a lot of racecars are made to "over akkerman") since the insidewheel does not carry a lot of load , its the outside wheel that matters ! , so when a driver gives a certain steering wheel inputthe car will roll , if the wheel would Toe In under roll the driver has to turn the steering wheel back a little , otherwise the car will turn a smaller radius than the driver intended , That feels very odd and unstable for the racedriver (and car)!!toe out under roll makes that the driver has to turn the steering wheel a little bit further into the corner , and Thats much muchnicer to drive i.ow the driver feels much more confident in the corner > faster lap times ,
