    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...

    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 років тому +7

      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 5 років тому +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.

    Okay, so let me tell you how helpful this video was. This is the most helpful video on suspension that I found on UA-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.

  • @ahmedhashem4454
    @ahmedhashem4454 4 роки тому +6

    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!

    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!

    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.

    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 :)

    @davidb.fishburn9338 6 років тому

    This video is very good. Makes things very clear. One thing needs to be added; That high positive caster is better for high speed stability, that's why the German cars and cars with German designed suspensions (Chrysler 300/Magnum/Charger/Challenger, to name a few) have the high caster.

    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.

    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 ?

    You'd make a good teacher of suspension and steering. I am a retired ASE Master Tech and S&S was always my forte. If you notice my Avatar, I bought a 2004 Marauder and put $7000 worth of upgrades in it in about 3 years. KVR 14" front rotor kit, Metco polyurethane bushed rear control arms and watts links, QA1 dual adjustable racing shocks on all 4 corners, ADDCO 1-14" rear stabilizer bar, Torsen T2 differential, and MMX Metals' 200 mph driveshaft. Oh, and a second set of tires for racing, Nitto Street Drag Radials, the rears on widend rims.
    For a 4300 lb. police interceptor *interceptor,* Quicksilver (that's her name) is like a roller skate on a rail in the turns. I've often outrun those German sports cars on twisty roads, cars with 100-150 more horses than I've got, because I'm able to wait until the last millisecond to scrub off speed before the turn with massive braking power, come off the brake and hold the turn under high g-force, and exit the turn under WOT with that differentiating Torsen T2 (limited slip is the absolute WORST thing to have on your car in road racing).
    And it's been my understanding of the things you teach in this video that has helped me to make the proper upgrades to Quicksilver and make her such a pleasure to drive. To all you viewers who watched this video: pay attention to SK8215, he knows what he's talking about.
