Rick & Morty had an episode on "true level" and it's a real thing😮 I'm curious about the weight scales being used when the whole car isn't on them... Good video HPA💪

I machined a set of those alignment fixtures for a Porsche LMP2 Spyder back in 2008

Another good one, extracting some special insights. Way back when I raced moto gp we always used string alignment method. Nothing else was trustworthy.

The Americans spent millions making a pen that works in space. The Russians took a pencil ….

@hpa101 2 жыл бұрын

That is actually a myth, and both the Soviets and Americas ended up using the same pens from an independent US company as pencils were less than ideal, but we 100% agree with the sentiment behind the myth - Taz.

There's another name for that flat steel plate they use to put car on to align it? Do you know the name ?

Great video. Those fixtures they mount to the hubs are very nice. I assume the center to center distance where the alignment fixtures rest on the scales is the same as the track width with the wheels and tires attached, correct?

I would have thought they would have some super high tech laser computer ultra sophisticated system for wheel alignment. Not a 1990s aluminum fixture and a ruler. But hey if simple works why change it

@hpa101 2 жыл бұрын

The concept is much older than the 1990's, however, still the best tool for the job. If something that is better in the necessary ways comes along I'm sure it will be adopted. With that said, this still is a pretty baller setup compared to many string based alignment systems. The calibrated floor, hub stands and light weight rig are not something you'll find in your mates garage as a rule. I doubt even the average laser system has a chance of being as accurate as these guys are here without some upgrades to the standard way they are used. That floor is beyond level compared to the average hoist for example - Taz.

Corner weight sound simple, measure the weight of each wheel load in a level surface. How do we adjust corner weight?

@connergreer9434 2 жыл бұрын

First you want to shift around components such as moving the battery in order to get the weight as balanced as you can, then you adjust your coil overs in order to balance the remaining weight

@@bernardwarr4187 No manufacturer is going to corner weight their road cars, so those shims will be for some other reason. It is only possible to accurately corner weight a car with adjustable height suspension (adjustable fixed ride height, not hydraulically adjustable or air suspension) and you can only use the method to adjust the combined diagonal weights, not move weight front to rear or side to side - that has to be done by physically moving components around as Conner said. Think of it like a table at a restaurant - it will rock diagonally if any of the legs are too short so if you shim or adjust the opposite diagonal to the axis of rocking it will sit steady and stable. There are plenty of great videos going in to more detail if you want to learn.

I didn't get it, how is the ride-height achieved? I guess those things that bolt to the hubs have to be articulated in each direction in order to allow for the setup change, so what is keeping the spindle at the correct level?

@derwhalfisch 2 жыл бұрын

Just a guess, but the height of alignment0hardware and the scales themselves are known. the scales will 'sag' under the weight of a car too little to impact anything. if you're asking how the changes are made, then it will be spring seat position+preload adjustment just like in a street coilover, tho this class ruleset might even allow for changing fulcrum position and nearly anything else in the geometry
