In this TYRANIS TIPS video, we explain shock positioning and how it affects the suspension feel of your go kart, minibike, or whatever it is you're building!
I totally agree. I am working on a project, and saw one of his videos, and expected 100k+ subs, then I saw it was in the 300's, and well, he gained another sub.
This was the 1st of your videos I have watched, phonominal explaining and if I were to guess what career path you have chosen, I would say that you were an instructor at a college somewhere. Thanks and look forward to watching more of your videos.👍
Wow, you explained it so well and had me so engaged I was surprised when the 16 minute video ended. I swear it was only 5 minutes. Great job. Question with some backstory: I'm considering turning my SUV into a full independent suspension, lite-prelander with dual rate coil overs. I also want to remove the sway bar to strike the best balance between chassis anti-roll and A-arm suppleness on the trail. If I were to run a very stiff primary spring and rather supple secondary spring as far outboard on the A-arm as possible, had the shock mounted perfectly vertical (in reference to the ground), and the lower control arm had, say, a 15 degree drop under 0 degrees (perpendicular to the floor), would I be able to generate enough natural "low speed compression" stiffness on my primary spring to drastically reduce my chassis roll while maintaining "low enough high speed compression" values in the secondary speing to keep the suspension supple in turns? Not sure if you can even answer that question. If you need me to clear anything up just ask.
In theory could i use longer springs in the rear to achieve lift? Engine sits on a swingarm that pivots from chassis with spring on each side (Coleman KT196)
Yeah! Or just make new mounts and stand the stock springs up more. You'll have to play with it but you can make that work. Your engine may sit on an angle though which isn't idea for oil distribution...
Great video. Question: So we have a known shock spring rate, as in your example, of 300 pds. So as a baseline to work out the math, at which point along the length of the A arm do we know it’s applying it’s rated spring rate of 300 pds? At 50% of the length of the A arm (as in your example)? I doubt you just picked a random spot on the A arm to start.
So, wherever your spring is bolted to the A arm is where your full spring rate will be applied. The distances I chose were just easy to draw and explain😅. The further in towards the pivot you mount the springs the softer they will feel as you give the kart more and more leverage to exert the force of its weight on your spring. I hope that helps!
I have a question about upgrading my shocks to taller and it has changed the toe angel of the tire. Here's what's happening, when I drive my gokart the front wheels toe out on both sides and it's difficult to drive. If you could help I will be grateful. Thanks
Yessir! It's all about the distance your shock is from the actual point the arm pivots, and the angle the spring is on in relation to what its mounted to. I use the same principle to figure out where to mount our rear shocks on our swing arm! Great Question!
I just subscribed to this, and I know that this is an older video. But I am building a 3:4 scale 1973 Porsche 911. I just got the motor in last week. It is from a 2016 CBR1000rr. I have not built the frame yet because I am a little concerned about it being able to hold the weight of the motor. I also purchased a pair of air ride shocks for a HD Electra Glide. My goal is that the motor will be attached to the same part of the frame as the rear axle enabling it to move up and down with the rear wheels. My concern is if that is going to be enough to keep the ride height level or not. Or should I add another pair of shocks to the equation? Also what is your opinion on counterbalancing the weight in the front?
This is all good and all but no go kart shock manufacturer states their spring rate. its all "max load" the common one is 450lb but how far does it travel for 450lb?
The ones we used listed a max travel of 2in at 450lbs. So if we know that, the equation is Spring Rate=Load/Travel. If they don't list at least 2 of the 3 variables you'd have to just load the spring, measure its travel under the amount of weight you put on and you could solve for it from there!
@@TyranisCustoms i figured it was about like that but didnt want to assume, 225lb/in is really high for a go kart, thats about how stiff compack car springs are
There is so much more than you are describing here this is a terrible video. Okay my bad I came off a little harsh let me reiterate if I may what I am trying to say is as a professional RU-vidr you have a responsibility to your viewers of giving them safe information. When it comes to building from scratch the front end suspension components and steering of a four-wheel vehicle especially cross-cart type vehicles with very fast engines etc etc just the basics are enough if you get my meaning. Caster camber bump steer and Ackerman are all crucial for a vehicle to work safely.
