"The suspension is too bouncy"

I don't know where these armchair physicists keep coming from. Kimmy, if you can give definitive evidence for your claims then do so. Gabester has been doing this since... when did that Lexus come out on Ror? about 4 years ago? We can grant him about 4 years worth of research and learning. The man knows more than I do about vehicle behavior-- I'm merely an engineer. Its a big boaty American car on 4 springs designed for comfort and accommodating Grandma's driving style. I don't like arguments from Authority, but I would trust Gabester on this one. Its not a performance car, its designed to float over bumps.

then again, kimmy, I would love to know what qualifies you and your opinion. You're not another one of the Gran Turismo experts are you? If all else fails,


(imported from here)

the car body, the part sitting on the suspension, is about 1500 kilos. Expect it to wobble on any kind of spring

 

off topic but how do i enable free camera in the game?

 

Shift + C.

 

I don't need to be qualified for an opinion... that's why it's an OPINION. now if I was stating that my opinion was a fact, that's another whole story. And if it makes it any better for you, I've grown up around cars... My father is a collector, so I've been in and/or driven a WIDE variety of vehicles from a 1925 Model T to a brand new Chrysler 200. I know how cars work, and how they behave under different circumstances. so I DO have quite the base to form an opinion on. Take it or leave it.

 

Anyone who comes from Poland is an expert on bumpy roads.



You'd be surprised how fast the locals drive on these roads.

 

No, but you need to be credible if you want anyone to take you seriously.

 

I think the most important fact in this whole issue is the kind of car you are talking about.
in first i thought the grand marshal would be to bouncy myself too but its a heavy american car... and its springs just arent supposed to neither bumps or high speed and after alot of testing i now think its pretty nice allready even if i would wish for more damping but well thats the car. im still unsure about the pickup but as i have very few experiences with pickups in real life or physic simulating software i wont even try to judge that.

Considering this, i really hope for modern cars with the ability to swallow bigger holes and bumps than the cars we have now without the frame hitting the ground.

 

The Grand Marshmallow's (I coined that phrase, use it freely) standard suspension is fine, its what looks like a mid 90's body-on frame american sedan that, at a guess, has the original 20 year old front shocks in it. It's the sport suspension I have a problem with. Also, the fact that the bottom of the shock is so close to the inside pivot of the lower control arm makes the coilover act softer, moving the lower shock nodes out by 20cm makes it muuuuuch stiffer up front.
My 1989 Firebird has the original shock absorbers in it, and it bounces about as badly as the Grand Marshal.

Also, somewhat off topic, if you use full steering lock in the D series, as it spawns from default (V8 AWD) it snaps the inner steering arm. Even after the update that lists "stronger steering"

 

Your father being a collector won't have any impact, right. I doub't he'd allow anyone to thrash such valuable cars. He probably has allowed you to drive things but its likely to have been very sedately on an easy road, or even just on the lawn. Money is worth something, he doesn't want you to crash them and even more pressingly, if he's a good parent then he won't want you in a crash after mishandling an old or powerful car. Tell me how many hours you've spent driving an old Buick Roadmaster on potholed roads at even 20mph?

and here's another consideration. I've noticed in NG that if the simulation is a bit stressful for your PC, rather than simply dropping frames the engine seems to 'slow down'. Its quite significant. You don't get real-time on a bad computer even though your FPS is probably passable. Could it be that you're viewing the engine in slow motion because of a limitation of your CPU and that's why you think its overreacting?

 

For the grand marshal it is fine. But if I see a car that is modelled off a modern SUV, especially a sport one, like an Audi S5 or BMW M5, and it bounces like that... I will have some more questions

 

Just dropping in another video, compared to this GMC Sierra the D-15 isn't bouncy at all.


Footage from "The Fall Guy". Pretty awesome how often that truck breaks considering that they've already reinforced the axles.

 

yeah well, the car of a tv series used for stunts in every single episode is not really any reference to compare to as it compares to a standart production line pickup as much as a dune buggy to a cheap quad.

but yeah, that thing was bouncy as hell, loved the tv show.

 

If you're talking about Bullit: Those cars were stock you dummy . The Mustang had to be repaired over and over cause the suspension kept breaking, whereas the Charger was never repaired once.
Only in the Dukes of Hazard you could argue it's not perfect reference because they filled the trunk full of concrete to level the car out in jumps. Back then they really didn't change the cars much for jumps...

 

That was hilarious!

 

i meant the pickup, not sure what bullit does refer to, i assume mustang bullit ?

 

As far as I know the Sierra wasn't upgraded much, it got bigger wheels, an aftermarket suspension kit and some welded on steel bars on the axles (you can see them in the video) and it still bounces as hell and breaks all the time. In some scenes you can clearly see that the truck lands on the ground, then there's a cut and then a new truck drives of from the same position the first truck has landed (and has broken down) before.
I posted that video to show how much a truck that looks like it could participate in a baja race does bounce even if it has big soft wheels and a foot of suspension travel. Regular cars will suffer from jumps even more since they lack these wheels and the suspension travel.

 

some welded steel bars... not upgraded much, just reinforced with stuff from which its made of in the first place XD
but ya imagined it would have been even more

 

I too feel that [h=2]"The suspension is too bouncy"[/h]
and I've never seen a car behave like this.

 

I would like the suspension to be more heavy duty for carrying stuff, like the box van, pick up truck, and normal van. ( carrying stuff is fun )
Other than that, its perfect.

In game you dont have the feel like you do in real life (as in you dont slow down as much, cause lets face it, no1 floors it on their daily driver and screeches the tires around every corner in life), so you go faster hence the bouncing around.
