Don't Waste Money On The Wrong Dampers/Shocks. PS: Don't Call Them 'Shocks' Either.

And whatever you do, don’t call it dampening 😉. It’s damping. Sorry, I had to.

[@gothicpagan.666]

Dampers and spring rates are one of the deepest holes you can ever climb down. Try going up on spring rate, backing off bump resistance, add rebound resistance to control the energy of a stronger spring. Then there's anti role bars, role centre and role centre coupling. Tyre wall construction, mass concentration, centres of gravity. 6 months of solid testing and you should get a real feel for what each does in isolation, but then you start combining various combinations AND THEN ADD AERO.😖 You will be hooked🙂

[@TML34]

Also need to factor in “motion ratio” to get the right spring rates.

[@giddyurp]

Yeah cool.. Suspension expert calls it a role bar, role centre and role centre coupling 😂 clearly a pro, or are you still traning for the role?

[@gothicpagan.666]

@@TML34 spring rate takes into account motion ratio. Example would be an inclined or bell crank spring mounting giving a rising spring rate. It's just terms that are used when we get it wrong at the design stage and have to come up with an explanation (Excuse)

Good tip in regards to adjusting to the extreme when learning how something works. Same goes with a lot of other things. Photo editing is a good example. Crank up the clarity, vibrance, blacks, whites etc from min to max and see what it does to the image, then you will have a good understanding of what that adjustment does.

[@PANTYEATR1]

I only built cars for the street that i would like to be capable of doing track stuff. What i do is corner weigh the car, so i can get the correct weighted springs. Then i adjust the ride height to reasonable limits, (usually 2 of my finger width between the top of the tire and fender). Then i drive on highways that I'm familiar with that have imperfections in the road. I adjust the suspension until there is no more scrubbing and the bumps are handled in an OEM+ fashion. Then you'll have a great driving car that anybody will get into and be comfortable and have minor adjustments when the springs start to settle. Thanks Andre and HPA TEAM 💪

as a wanna be sim racer this talk was great at helping really understand what some of the settings in ACC are.... Thank you!

[@scottsmi16]

To understand hi speed and low speed damping I was told hi speed is wheel control and low speed is body control it made it much easier to understand for me 👍

[@makantahi3731]

there is only how much force is on damper , it is controlled by springed valve, that has different oil flow by its travel, how much, it is defined by spring preload and how big are passes on certain positions of valve

[@melaninfuture]

It’s all about negotiating weight distribution to meet your specific driving needs. Depending if you’re in a FWD, RWD, 4WD, etc., and other important factors including aerodynamics, type of tires, etc. you want the vehicles’ weight and momentum to be at the right place at the right time when you’re delivering steering input to the car.

[@aukanmeister]

Play with the knob. Got it. Good tips to get started here, boys!

[@hpa101]

When you boil it down, it really is that simple with the basic suspension setups most of us have in our street turned track cars. People overthink the small stuff - Taz

[@Soravia]

Tune the springs first, then dampers, then anti sway bars aka load transfer bars.

[@TML34]

Where people get confused is between shocks vs. struts. “Dampers”, as a generic term, could be used to describe both of these, but there is a fundamental difference.

[@hpa101]

So long as people know what you're talking about it's not really a big deal, we do agree with that for sure 😎 - Taz.

Rebound / compression ratio for comfortable street use ??

[@mercuriallimit]

how often do you change these dampers and absorbers for everyday use. Coming from a stock, I have no idea.

[@gordowg1wg145]

A rough rule of thumb may be high speed adjustment for the wheel control and low speed for the chassis/body control?

[@makantahi3731]

high force opens valve and dampers travel faster, on low force that valve is closed and dampers travel slow

[@gordowg1wg145]

@@makantahi3731 If you reconsider that order, you may then understand the operating principle of the hydraulic damper. Hint, start with velocity.

@@makantahi3731 I use years of experience as an actual Automotive Engineer. Perhaps you should re-read your "manual", as it is you're just digging a deeper hole because it's absolutely clear you have no idea. BTW, the "speed" and "velocity" I mentioned earlier is that of the compression or extension of the damper shaft within the damper body - NOT the vehicle speed. That's another hint, BTW.

[@AutoEngineerVideos]

No no no no no!!! It isn't "dampening!" It's "damping!" Dampening is making something slightly wet. Damping is deliberately wasting kinetic energy in the suspension to slow down wheel movements to keep the ride, handling and grip/traction within desired limits/characteristics. As an educator in the automotive performance field, you should know this! If the suspension "dampens" something, then it's leaking oil and it needs to be replaced.

[@Backyard_Racing]
