As a mechanical engineer I enjoyed every second of this video. So underrated channel. I'm subscribing!

I just subscribed because of this video. When going through the comments I spotted yours and had to reply to confirm your true words :D.

[@off-roadingexplained8417]

Software engineers like it too , lol ;-)

[@096frost2]

Us arm chair engineers also like this!!

[@oren1419]

If you would like to go even deeper with your explanations it would be great and I think that many will appreciate it! Maybe even do a whole video for nerds only! Great work man!

[@azargelin]

Totaly agree

[@walkercam]

Yes please! Very keen to see some more behind the scenes of your suspension calcs.

[@umedina98]

TOTALLY AGREE

[@EvelOttos]

Same here. Fire up a Patreon account. I would totally give you a buck or two per video for in depth analysis and calculations on designing the suspension. It would save me hours from breaking out my old text books and re-learning it.

[@umedina98]

[@gafrers]

Awesome build. Every single episode is better than the last. Great to see progress and the explanations are always on point.

[@Tommy_Poole]

You’re being very brave showing this build and in this much detail as you’re bound to to be criticised by people who think that they know better. Good for you for having the facts to hand to prove that what your doing is correct. Can’t wait to see how you tackle your next set of problems. Keep up the good work.

Canadian car builder DESTROYS armchair suspension experts with FACTS and CALCULATIONS

[@eumoria]

I CAN SEE FROM THIS VIDEO THIS CAR IS INADEQUATE. MY PROOF IS MY FEELINGS.

[@bintangsena2249]

BOOOM

[@johnterpack3940]

Your comment is paradoxical. By throwing around an epithet like "armchair expert" you are asserting that you yourself are an expert capable of judging the FACTS and CALCULATIONS presented in the video as being true and accurate. Yet you simultaneously insist that nobody else is capable of judging the FACTS and CALCULATIONS and pointing out errors. So you and the guy in the video are the only two people on KZbin who understand physics or suspension and you are both infallible. He did make FACTual errors in the video. Most notably when he said pushrod suspension reduces unsprung weight. Anything that moves with the wheel is partially unsprung weight. That includes the pushrod and bellcrank. Bolting the coilover across the top of the chassis doesn't make it less a part of the unsprung weight than bolting it directly to the control arm.

[@isaacmadhavan]

@@johnterpack3940 So, are you saying that anything bolted to the chassis is unsprung weight?

[@johnterpack3940]

@@isaacmadhavan anything that moves with the suspension is unsprung. If it is also bolted to the chassis then it is only partially unsprung.

[@bahadrd1579]

That explanations of calculations are best parts of your work. Perfectly engineered

[@diggleboy]

I'm drooling over the physics explained in your video! :) Facts, Science, Logic & Reason are the undisputed champions in any dispute. Bro-science vs. Physics! Physics wins every time and your patience to educate all the bro's on Reddit and on your channel is extremely appreciated and very valuable. It's never about right or wrong, it's what matters most to making it work properly in the end. Thank you for patiently explaining the suspension design, calculations and formulas, and the graphs in Excel you used to make sure you were within the limits of your design. I am eagerly awaiting to see you race your E55 ASL track monster once your project is all finished. :) Say the word and I'll be there. Now, it's back to work for me.

[@christhjian9923]

It's been said here before, but after you'd be done with the project, I also would love to see an in-depth video about entire critical calculations that went into the design. I feel there are not many people who could explain it as well as you. I've been watching these videos multiple times already and will continue to do that to remember as much as I can! And owning the keyboard warriors was simply legendary :)

[@pjvenda]

Loved the explanation at the end, huge credit for being able to back up your decisions with actual calculations and simulation data. Killer quote: "cars are not designed by people standing around in a circle and looking at something and the judging how strong it is. There are actual methods to calculate how much stress something has to go under....."

[@jacobrohr5903]

This thing is gonna be crazy fast when it’s done. Great explanation about the engineering behind it.

To many folks trying overthink this for you, its yours to break.... Not to say that it would of course, but your the one doing all the work here! And it looks great! You've done the math and now your doing the work! Cant wait to see this project completed!

[@labmancdn]

Thanks for taking the time to share things in such a detailed manner. I think you have renewed my decision to design/build a pushrod suspension on my project car. I think I was trying to get a little too complicated and you have brought it back to a much simpler approach for me. It's rare to see someone share build steps at this detailed of a level. Please keep it up. Look forward to watching through to your project completion!

[@ajhartmanaero]

I like when you get into the numbers to support your decisions. Love these videos.

In theory there is no difference between theory and practice, in practice there is - Yogi Berra. This project use physics - where you try to describe the reality through a model, opposite of math that is kept pure theoretical. The reality always win, and the models is always adjusted to the world you observe, this is empiricism and why sceince is evolving. Theory is a shortcut to easen the work, foresight reality and avoid failure. - sincerly a manufacturing engineer that is parttime behind a computer and parttime on the shopfloor.

[@HUBBABUBBADOOPYDOOP]

The angle of incidence is equal to the axis of inclination. As with Billiards or the articulating geometry of a suspension- there are definable rules and formulas that must be followed. You are doing an awesome, complex fabrication, with all the science, math and graphs to point it all out. Haters are just yankin your chain; pay no mind to their drivel.

[@tommywright517]

This build is insane. I love it. I’ve put a few cages in some Honda oval track cars as well as slight custom Chevy chassis’s for oval and figure 8 tracks. This suspension could be the next big thing for us as in keeping the shocks within the frame rails so that if our wheels do make contact and damage suspension it doesn’t damage a very expensive coilover.

[@Angel-HC]

I really like the level of engineering used here. As someone who's fascinated by suspension design I definitely appreciated the level of analysis and reasoning you presented. Also, thanks for the explanation of the heim joint orientation. I was curious at the start why horizontal was better, more from a consideration of available travel compared to mounting vertically. I hadn't considered that the stress on the ball/socket interface from the longitudinal force on the suspension would be significantly higher compared to having them horizontal.

[@dicktaylor2600]

Great project,can't say I would be comfortable with some of those welds,especially where the inner damper mount is welded to that X member.

[@marcwire9332]

who ever the haters are they have no idea, we use basically the same materials to build suspension, at present the race team is building a new drift car same ball joints, drift puts that front lower arm under massive pressure and they still hold, in fact the only way to go due to the massive aggressive loadings involved would compress most bushes and create play in the steering. Love the design, very inspiring!

Cool design, video, and narration.

[@tiitsaul9036]

Awesome. I was literally just minutes ago watching your older videos and wondering when are you going to upload new video. And then this one popped up in the suggested box.

[@DeVoN420zz]

front suspension mounts/ball joints do not look strong enough for CASTER type loads, Especially because SLA suspensions usually have a positive scrub radius, your scrub radius looks very negative.... The greater the scrub radius (positive or negative), the greater the steering effort and the more load it puts on parts and you get more road shock, pivot binding, torque steer, 0 degrees of scub is also bad it will wiggle, 17:44 your changing your scrub radius/ Steering axis inclination/ mechanical leverage

[@alacnop]

Effective scrub radius appears to be 0, not sure where you think the negative scrub radius is coming from. His steering axis appears to meet the tire center line at least during straight line travel.

[@zdrafkoprhuda2494]

He sai that he will have around 40mm positive scrub radius.

[@autospeed]

Excellent video man. Ignore all the idiots on reddit. Clearly you know what you're doing since you've built and tested these components. Keep the content coming, I'm glued to the screen everytime you put up a new video!! I was going to say I'm an engineer myself and would love more explanations of your calculations, even if you started a second channel dedicated to the maths that would be really awesome!

[@bryantb3391]

Awsome man been wanting to build a car but i would like to learn how to make my own suspension ive learned about pushrod style after wondering where the coil overs were on a f1 car also the setup u got and idea u got is awsome for a turbo

[@kiamaz254]

[@TJBRENTON]

Great stuff! Anyone who says this is too light weight, or it will fail when it see the track - Go look at most 60-70's Formula cars, or even stuff like a Mclaren M6. Where this guy is using 12mm rod ends, they used 8mm! Admittedly their fabrication is more aero grade. I reckon your safety factors have a safety factor ;-) Keep inspection regular and look for cracks. Not sure I like what you're doing at the end of the wishbones. Looks great and I look forward to catching up with your videos.
