What is suspension stiffness?

A stiff suspension will make sure it’s pushed exactly where it needs to go. Your softer road suspension will keep your back happy so you’re not bouncing over every imperfection in the road. The proper setup for you might fall somewhere in between, and if you watch this video you’ll know why.

Which is better soft or stiff suspension?

The purpose of a suspension is to keep your tires on the ground. A softer suspension will offer more mechanical grip as it will do a better job of keeping the tires on the ground vs a stiff suspension when it comes to depressions, bumps, and surface irregularities in the road.

How do you soften a stiff suspension?

How to Soften Car Suspension

1. Install softer shocks and struts. As the primary component that affects your vehicle’s ride quality, shocks and struts have a very big impact.
2. Adjust the shocks to a softer setting, if you have adjustable shocks.
3. Install softer springs.
4. Replace the bushings in the suspension.

Should front springs be stiffer than rear?

On very high-grip tracks, it’s usually beneficial to stiffen the front, even more than the rear. It just makes the car easier to drive, and faster. Softer Front Springs: The car has more steering, especially in the middle part and the exit of the corner.

Is stiff suspension good or bad?

A stiffer suspension reduces the reaction time and makes the driving much easier. Aside from that, less roll improves the aerodynamics. If you have an air dam that is almost scraping the road, when the car leans, it will be scraping the corners of the air dam.

What determines spring stiffness?

Spring stiffness is based on spring rate . If you lower the amount of coils, you’ll increase the spring stiffness which is the spring’s rate. If you adjust the outer diameter or the wire diameter, you will affect spring’s force and stiffness as well.

How do you find the stiffness of a part?

Its stiffness is S = F/δ, where F is the load and δ is the bending deflection.

What is the advantage of stiff suspension?

A Stiff Suspension Will Allow Your Car to Accelerate Faster If your suspension is stiffer than the wheels, it will be able to grip onto the road without slipping, which will allow you to accelerate faster. This is especially important if you have a sports car since this way you will help it perform at its best.

Why does my car hit bumps so hard?

Rough, bumpy rides can be due to bad tire alignment, incorrect air pressure – too low, too high, different pressures in each tire – or even the tires not being mounted properly. Worst case scenario could be the rims themselves have become damaged or warped.

Do Rally cars have stiff suspension?

Rally cars use different suspension based on conditions / surface they are driving on. For tarmac only rallies, they use harder, stiffer suspension and the car stance is way lower for better handling, while for gravel racing, suspension is high and soft to better sustain an impact on landings after the jump.

What happens if your suspension is too stiff?

While too stiff of a suspension may mean going airborne when hitting a bump, it can also mean not contacting the road quick enough if there’s a drop in the road. Imagine we have a car with a super stiff spring on the front left tire, and a super soft spring on the front right tire, heading towards a 20 millimeter indent ahead where the road drops.

Is the front of the car stiffer than the rear?

If that means the rear is stiffer than the front, as might be the case on an MR car, then fine. Lately for me though, it has often meant the front <1.0kgf/mm stiffer than the rear.

What suspension settings do you use for drifting?

I’ve been drifting GT4 for a while now and have made a few posts. Majority of the suspension settings that we’ve made (I got a few myself..) are to make the Front stiffer and the Rear looser. This makes the tail easier to slide out and drift.

How does the spring rate affect a car’s suspension?

Again, going back to imagining a spring with an infinitely high rate (a fixed suspension), you’d simply rely on gravity for the car to drop down into the divot. With a lower spring rate, the force pressing the tire down remains higher longer relative to the amount of travel it has, so it contacts the ground much sooner.
