Well get started with the basics that apply to any car and well progress to more advanced setup topics, which are only applicable to high-end cars. Its configuration determines how much of the torque coming off the engine is transferred to each wheel. They can quite literally be the difference between first and last place and the higher the strength-of-field, the more that they will determine that. And in a later article well look more closely how to approach dynamic ride heights. This essentially causes spring stiffness to have no significant effect on the mechanical balance (lateral load transfer distribution and roll) of the car. As always, its important to experiment with each setting to gain experience with the car and to develop an instinct for how to approach differential setup. The ARB connects the suspension elements of two wheels on the same axle. Now we understand how an axle can lose grip under cornering, and is this precisely what causes handling issues. We recommend you take either of these for a spin on low tyre pressures, so you get familiar to the feeling of too-low tyre pressures. Getting started Register your account now to start using Setup Sync! 3: Ground clearance It's better to learn collision avoidance in rookies, than jumping to higher level races without understanding proper racecraft. 2: Balance between downforce and drag With this we mean the bumpiness of the surface, and the lengths of the straights, and whether there are many fast or slow corners. There are a number of third party software tools that integrate with iRacing to improve your simracing experience or to aid you in your driving practice or racing. Side-by-side racing is just something you cant do in rookies. Stiffer rear springs give you a more consistent handling through the corners, while softer rear springs will give less drag on the straights. The differential (or diff, for short) allows the left and right wheels to rotate independently, which helps balance the car through corners. I am pretty consistent. It is there to improve your site experience by saving your preferences. This can improve the balance of the car, and increase overall grip on the axle as shown in the earlier example. $4.99 per month for their Dedicated package, or $9.99(or $99.99 if you pay for a year in full) for the Competitive package. If there are more than 9 iRacing setups available for this car/track, look for the navigation links near the bottom of the page. I was following the leader for about 15 laps within .5 seconds, and within .2 seconds for about 8 or 9 laps. Dirt StreetStock: 2/27/2023. A stiffer rear ARB thus reduce available grip at the back while increasing it at the front, hence, making the car more oversteery and less understeery.

Most open diff cars are underpowered, however, high-powered open diff cars (or cars with open limited slip differential), may spin the inside wheel on corner exit. To understand how balance is affected, we need to understand that as vertical load on a tyre is increased, the coefficient of friction of that tyre decreases. When going around a corner, the outside tire has to travel a longer distance. A higher tyre pressure alsochanges the curvature of the tyre, from a flat shape to like that of a bicycle. 2 wins under my belt and nearly 6 lost cause of a person accidently pits me. Load the setup in the iRacing simulation under Garage My Setups. Lets say that number is 4 laps. Cornering causes lateral (left/right) load transfer at each axle. For instance, during braking a car with softer front springs compresses more on the front, which pitches the car forward (dynamic reduction of ride height at the front). Using the ARB to balance the car Tuesday at 18:58; 3; si far I've done 3 races on rookie Street stock, coming in 6th 11th and 2nd. Creating your own setups is time-consuming though and with the busy lives that most of us live, wed rather spend the small amount of free time that we have available actually racing I know I would. 2013 - 2023 Smarty Co. All rights reserved. Gaining proficiency in car setup is a process that requires you to experiment and analyze a lot. Adjust these properties until your achieve the desired measurement for ride height. A spool gives you good traction accelerating on a straight line, but the handling of the car is compromised during turning. This is an internally generated cookie that we use to hide our SMS form if our users have signed up or indicated they are not interested receiving SMS notifications. The more locking force, the more it behaves like a locked diff and vice versa, the less locking force, the more it behaves like an open diff. As you can already guess, for long runs its a little different and this will be covered later on in a more advanced section. Purposes of changing the ride height As a general rule of thumb, on tracks with lots of low speed corners such as Okayama, youll want to run relatively low pressures, because compared to high speed circuits like Spa, the downforce generated by the car is fairly low on Okayama, and therefore the loads on the tyres are lower. 1: Lower center of gravity means less lateral weight transfer, which means more grip For now, start your setup crafting career by finding the right tyre pressure. Interested in special offers, free giveaways, and news? A stiffer rear ARB causes more of the lateral load transfer to be distributed to the rear axle. Vertical load will increase on the outside tires and will decrease on the inside tires. This helps with turning. In oval racing, its much easier to learn the tracks, so car setup is a quite significant factor in open setup series. Lets work through an example, using the chart above. Unlike the front ARB, the bar in the rear is adjustable in stiffness. Going with softer springs could solve the bounciness, but in return could hurt the pitch and roll attitude of the car, and may influence suspension geometry (such as camber), and consequently hurt aerodynamic effects and possibly cause aero-related handling issues. This single spring design at the front is called a monoshock. si far I've done 3 races on rookie Street stock, coming in 6th 11th and 2nd. DIRT STREET STOCK SETUPS. A locking differential can behave both as an open differential and as a spool. The $4.99 tier will give you access to one car setup that you choose when signing up. See the illustration for the difference between pitch and roll. So from trading paint on the short tracks to working different lines around the intermediate speedways and drafting on the superspeedways, the iRacing.com Street Stock Class C series has something for every oval sim-racer. Matching front and rear ride heights may be all you need to convert a qualifying setup to a race setup. Some series are very generous with people posting up their setups each week. The dynamic ride height changes throughout a lap, for instance when a car goes over a curbstone, or when downforce compresses the springs. One of the few setup options available to the Skip Barber car is the pressure in the tyres. By statically and/or dynamically adjusting the ride heights, you can optimize the aero performance of the car. Nummer 2 - 2018; Nummer 1 - 2018; 2017. The locker mechanism unlocks the wheels during corner entry and mid-corner and locks them on corner exit, when on the power.

The best way to pass is just force your car down low on the person you want to overtake, just make sure you don't clip their rear end. The bounciness of the car. For cars that are not very aero dependant the ride heights are primarily used to affect the center of gravity. When the pressures stabilize, you have reached the stable operating temperature of the tyres. Nummer 6 - 2017; Nummer 5 - 2017; Nummer 4 - 2017; Nummer 3 - 2017; Nummer 2 - 2017 First of all, you need to understand what an ARB is and what it does to the car. Each car is different, but in general theres an ideal ride height range that produces maximum downforce. 500 kg x 1.11 =550 kg (left tyre) So, the inside is forced to rotate faster than it needs for the turn radius and hence spins. You can also use the anti-roll bar to help restore the balance of the car, just never change it together with the spring rates, because it makes it hard to tell which change is causing which effect. This means that if you want to just jump into a random IMSA race one day, or maybe give the F3s a try, then youll have a great setup available for you, ready to go. It only provides stiffness in heave (vertical) motion. You may want to adjust the ride heights to avoid bottoming out on bumps and curbs. Its measured in Newtons per millimeter (N/mm) or pounds per inch (lbf/in). If you ask too much of the car (overall Gs), the ARB wont help.

No matter what I try in practice I can't seem to get below that until fuel burns off. The dynamic ride heights also changes throughout a stint, for as the fuel burns off and the tank empties, the car becomes lighter and therefore rises. I was drafting about .3s behind the car in front when someone spins in turn 2, I let off the gas, he hits the brakes. Open to Class C Oval drivers and above. . You must log in or register to post here. No more cutting/pasting or dragging and dropping between different Windows explorer windows. To give an example of an ARBs importance: When a car without an ARB installed goes through a fast right-hand corner, the inertia forces the car to lean to the left side, which is on the outside of the corner. Such a setup would produce more rake (and downforce) in the slow corners and less drag on straights. Welcome to the Unofficial iRacing Reddit Community. This simplifies the front spring rates setup. By optimizing the diff setup, you can improve your car handling through a corner. For example, for many cars converting a qualifying setup into a race setup (or vice versa) only means adjusting fuel and the static ride height. And during cornering, lateral forces cause the body to roll which compresses the springs on the outside tires. Yes, you can just park your foot on the gas pedal -- but, no, that's not going to guarantee you consistent times. A softer ARB causes less lateral load transfer on its axle, compared to a stiffer ARB. The Charlotte Motor Speedway built a new infield road course, designed specifically for NASCAR competition, in 2018. You have to use telemetry to find out after how many laps this takes. I have played around with them before and I have an okay idea on what tweaking certain things do, but I do not have the time or want to create my own. . iRacing's in-game options control panel - Click "Strength" and it will change to "Max force" If you are using Load Cell pedals, set the Brake "Force factor" to 0. These two ranges may or may not overlap. Bring a 3.42 rookie it sucked soo bad getting here. If a spring rate adjustment (for a different reason) results in undesired impact on roll-stiffness, youd counter that effect with an ARB adjustment. Well start with the Skip Barber RT2000, as it is the first open-setup car for most road racers, and also a car thats understandable and sensitive enough to observe setup differences with. On tracks with short straights and a wide range of corner speeds (such as Motegi), youd like to start with stiff springs on both the front and the rear. With the turns so gentle and banked, you can almost lay a brick on the gas and take a nap. iRacing We are the world's premier motorsports racing game. The iRacing , NASCAR hall of Fame driver Tony Stewart will make his first start since 2016 in the Xfinity race at Indianapolis Motor Speedway on July , Coming off of a very successful 2019 racing season, Billy Pauch Jr. only has one regret. YouTube, there is software to help you with that as well. Consequently, there may not be enough torque going to the tire on the grippy surface, so acceleration would suffer. It works pretty consistently with the rookies. Couldn't preach this more. I like to juke like I'm going to pass right on the back straight, then pull down low when the person in front tries to block. Open differential Pricing Personally, I wouldnt rely on the iRacing forums to find setups. The regulations allow the FR2.0s ride height to be very low, as a consequence you can run the stiffest front springs and still achieve your desired front ride height. For further explanations on the matter of ARBs, please see the more advanced chapters of this guide, which well publish soon. Do not attempt to open the setup file in Windows. If the car is nicer to drive and/or quicker, go into the same direction with the pressure another time. The open diff presents challenges in low traction conditions. Each car is different and it takes a bunch of experimentation with each new car to find out what works and what doesnt. Bristol Motor Speedway Asphalt Street Stock Setups; Charlotte Motor Speedway Asphalt Street Stock Setups; Concord Speedway Asphalt Street Stock Setups; Five Flags Speedway Asphalt Street Stock Setups The coefficient on the left tyre decreases from 1.25 to 1.11, while on the right tyre it increases from 1.25 to 1.35. Stiffer springs will reduce body roll. Spring rates and their effects Locked differential (also known as a spool) Because the rear spring rate changes multiple parameters of the car, such as the ride height, you could correct those accordingly to maintain the same static ride height. Someone will eventually wreck you (on accident most likely, though it still hurts your SR). In order to increase ground clearance, youll need to decrease the perch offset on each wheel, or increase the pushrod length (when available). With datapacks, you can easily compare your own racing and consequently improve. On tracks with fast straights and many flat, slow corners (such as Gilles Villeneuve, Montreal), youd like to start with stiff front springs and soft rear springs. iRacing Setup Sync is a platform created by Nick Thissen and contains a huge library of free iRacing setups. Like discussed in the spring rates article, bottoming out can cause handling issues as one or multiple tires may become unloaded or lose contact with the track altogether, and it can also severely lower speed when the car is dragging onto the track. 30 iRacing datapacks (setups, replays, telemetry) now on VRS. IMSA iRacing Series: Sebring International Raceway - International. And so the front roll-stiffness is solely controlled by the front ARB, which is adjustable in the real car, but is fixed in iRacing. However, heres a starting point when you think about each diff setting: Static ride height is one of the key setup adjustments, and also one of the easiest to get right. An iRacing membership provides entry into the newest form of motorsport: internet racing. Youd consider changing the ramp when you want to modify handling under braking (entry) without impacting the handling under acceleration (exit). Applying it to the FR2.0 The spring rate is the measure of spring stiffness, and represents the amount of force required to compress the spring a certain distance. Run by Fans of the Worlds Leading Motorsport Simulation Game. Youd need to drive 4 + 5 laps (4 laps to get the tires warmed up, then 5 clean laps within a few tenths of each other). In this article well explain what ride height entails, how you can adjust it, and how it affects other setup adjustment. The $9.99 tier gives you access to setups for every car in the service. You can view and compare different packs here. As we saw, both a spool and an open diff have their issues, especially in racing conditions. Necessary cookies are absolutely essential for the website to function properly. Towards the end I am usually down to 36.1 to 36.2s, maybe even 36.0s if I have a decent draft going, I am yet to break into the 35s however. And if you really dont care about anything i just said, and still want to jockey for position, then i would say the way to pass in the SS's is to go high on entry, coming down at exit (as long as its clear) and passing on the inside of the straight. Im a long time lurker on this sub, and i race oval exclusively. 300 kg x 1.35 = 405 kg (right tyre) Each time you add and remove fuel youd generally want to do so without actually modifying the static ride height (with some exceptions, depending on car or track).
