    This is 'the' BEST video on suspension geometry...Thanks a lot ! (I worked as an automotive diagnostic equipment service engineer for years, and i know what i'm talking about) Please do videos like this and don't worry about the length of the video... its good info...

      It's kinda funny that he seems to almost apologise for the video being too informative.. ;-)

      He should get an editor and clip the video into pieces. 10 min videos are optimized for viewer attention and ad revenue!!

    This is really good stuff. Steering/suspension geometry is one of the hardest things for me to understand conceptually as someone with no real practical automotive or engineering experience, just an interest. I'd love to build a little sports car like your own someday, it seems so cost effective for the amount of thrill you get.

    • @TastyChevelle
      @TastyChevelle 5 ปีที่แล้ว +6

      After all of the money you spend in custom parts the most cost effective option is a used Miata. Expect to spend at least $20,000.

    • @Pube83
      @Pube83 4 ปีที่แล้ว +2

      Just check miata forums, craigslist and autotrader. A miata with aftermarket suspension parts and wide wheels/tires can be had for $5k on up. The most economic, reliable fun you can have on four wheels. If you can DIY even replacement engines and trans are dirt cheap.

    This is the best video about suspension geometry I've seen so far. Really helpful how you actually showed the effects of different adjustments in geometry!

  • @stahlino
    @stahlino 5 ปีที่แล้ว +67

    You did way more than just your homework! Your explainations combined with your geometry animations make a complex and mostly "hidden" part of your car unterstandable for every level of car enthusiast!

  • @codypendant6745
    @codypendant6745 6 ปีที่แล้ว +1

    This is the most complete and easy to digest TH-cam video on suspension geometry I have seen yet. Thank you for including all of Caster's effects as well as reminding us about the pros and cons of KPI.

  • @JCOgle

    This is a fantastic video. I've been racing for decades, and have read many books on suspension geometry, but do not consider myself a master of the topic. You are, and this video brought it together in a way I haven't found elsewhere. Great job. I appreciate your efforts.

  • @oldprophet
    @oldprophet 5 ปีที่แล้ว +1

    Simply amazing. The steering geometry can be quite difficult, but thanks for teachers like you, we get to learn and apply what we learned. this is a must if we want to keep our tires rolling properly and helps us on the tire tread wear. Thank you SK8215.

  • @kanglinliow3535
    @kanglinliow3535 4 ปีที่แล้ว

    This is just golden! Provided me insights of how every parameter in suspension components work in conjunction with one another!

  • @ahmedhashem4454
    @ahmedhashem4454 4 ปีที่แล้ว +5

    Man you are a great teacher; you can take a learner from zero to pro. That's an incredible skill that not much teachers have. Your explanation is so clear and simple that a beginner can understand, and your understanding and fluency is so good even going into advanced concepts.
    I'm not even gonna start talking about the great animation and the amount of work and dedication you put in that, but man that's a master piece.
    I'd like to thank you on behalf of the world!

    This has to be the very best explanation of steering geometry on TH-cam. Well done. Clear examples, good images, just great all around.

    Thank you for providing this resource in such a clear and concise way.

  • @davethielke3916
    @davethielke3916 5 ปีที่แล้ว

    Great stuff. I sure wish this clear information and graphics were available when designing and racing back in the 1950-60s. Few people really understood more than a few basics, lots of tall tales and the rest was "Magic" that sometimes worked and other times got you in deep trouble.
    Looking forward to watching the next video, thanks for all the hard work you put into them.

  • @daveshongkongchinachannel
    @daveshongkongchinachannel 3 ปีที่แล้ว

    I've always had a basic overview of these things but every time I attempted to delve in deeper it became confusing. This is by far the best explanation of steering geometry I have seen. Thanks for making the effort to put this video together.

  • @wecirclethesky
    @wecirclethesky 3 ปีที่แล้ว

    This is a fantastic video! I'm just looking into steering geometry and this brilliantly covers all of the parameters and details. Will be keeping this video as a technical reference manual. Thank you and keep it up!

  • @slimshim1467
    @slimshim1467 4 ปีที่แล้ว

    Indeed. The part demonstrating the caster as it 'sinks into the ground' makes this the best video on suspension geometry out there.

  • @mm-tc3kt

    Okay, so let me tell you how helpful this video was. This is the most helpful video on suspension that I found on TH-cam so far. I am 35 years old and I am a life long learner. This has been the most amount of education I have received in such a short time in years. Thank you so much for this. It is Thanksgiving evening and I'm lonely and I am drunk and I am watching videos and suspension and this was such a joy to watch.

    Honestly dude this is the best vid on suspension geometry I've ever seen. I've been looking for some time and I give you a big A+ for this vid. The diagrams are excellent. Now I finally get what the KPI angle is and how it relates to caster. I am new to tracking my RS and I want to understand what is being done regarding suspension adjustments. You cannot sort out your cars suspension without a comprehensive working knowledge of this stuff. Thanks for putting in the time to educate me in this area. Finally I see !! An epiphany :) Much thanks. I will now move on to Part 2. Cheers. Oh yeah - new sub :)

  • @ropehitch
    @ropehitch 5 ปีที่แล้ว +1

    Great work. Very clear. I definitely learned much from this vid. This is the best explanation of suspension that I've seen. I'm not stupid but I have struggled with some of these concepts in the past and watching this I realized it's because in the past I was presented with the intended result of a particular modification, but not "why" or "how". You nailed it. Don't worry about the length; I appreciate that you're not "dumbing it down" .Complex topics take time. I'm happy that I've found someone who understands it to this level... AND has the ability to communicate it. Thanks so much for the quality content. Looking forward to watching all your videos. How did you become so knowledgeable about suspension ?

  • @piotrpaczuski4060

  • @edo386
    @edo386 4 ปีที่แล้ว

    I had an awful positive camber on the left front tyre that was causing excessive wear on the outside of the tyre, this was so extreme that the tyre ended up with a conical shape, I rotate the tires inside out to compensate wear but it messed with the straight line response the car is now turning left and I have to compensate, a camber correction was made at the alignment shop and I wanted to understand more about the steering and suspension angles, this video was the best I've found about it. Thanks!
