You should be able to distinguish driver errors causing understeer, from a car setup change causing understeer. We use cookies to improve your site experience. Press J to jump to the feed. If you ask too little, you wont notice any difference in handling. Stiffer rear springs give you a more consistent handling through the corners, while softer rear springs will give less drag on the straights. Keep in mind that many suspension elements are connected. A spool ensures both left and right tires rotate at exactly the same speed. 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. Locking differential Explains the function of each adjustment. Super simple, nothing fancy about the layout of how its done. With the turns so gentle and banked, you can almost lay a brick on the gas and take a nap. iRacing Setup Sync is a platform created by Nick Thissen and contains a huge library of free iRacing setups. Yoeri Gijsen; Feb 22, 2012; Replies: 1; Views: 17k; Replies 1 Views 17k. 0 . In terms of handling, an open diff gives you oversteer at the entry of a corner, and will understeer at the exit. You can do your setups yourself if youd like, and this is a really good idea to at least have a go at some stage in your sim racing life. 3: Ground clearance Locked differential (also known as a spool) A limited slip differential might have any (or none) of the following adjustments available, but heres what they do: Each car in iRacing has a different differential settings available, under different names and configuration values. Its configuration determines how much of the torque coming off the engine is transferred to each wheel. Unless you are within 0.2-0.5s of your fastest teammate, or a VRS datapack, you are probably better off working on your driving style. I still have an active VRS subscription as well but for the time being, I am using that for the software and data that they provide and not as much for the setups anymore. A given tyre pressure is ideal for one specific amount of load on the tyres, yet this load varies greatly because of the different amount of downforce generated through high and low speed corners. As a result, as soon as one wheel moves up or down, the other wheel is forced to follow that motion. Once youve read this article on where to find iRacing setups, I wrote a guide on how to install them. eNASCAR Class A, B, and Class C Truck Setup Guides, 30 iRacing datapacks (setups, replays, telemetry) now on VRS, 5.4: Spring rates basics (Formula Renault 2.0), 5.3: Anti-roll bar basics (Skip Barber F2000), 5.2: Tyre pressures basics (Skip Barber F2000), 1.4.2: Hardware, steering wheel, pedals & rig, Additional Terms of Use for Coaching Platform. 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. iRacing Street Stock Series The Street Stock Class C series represents a significant step up from the rookie series, with a schedule featuring a mix of iRacing's most popular short tracks, intermediate and superspeedways. Youll find that there are often a lot of setups posted when a new car has just been released. Once you get into a race, the same argument applies. The Charlotte Motor Speedway built a new infield road course, designed specifically for NASCAR competition, in 2018. Get the Skip Barber out for a spin, and see if you can adjust the ARB to your liking! 2018. In practice, when setting up the car, adjusting spring rates comes in handy when optimising aero effects, and the tradeoff is typically between aero related time gains (lower drag on the straights) and car handling (more downforce in the corners). Each car is different and it takes a bunch of experimentation with each new car to find out what works and what doesnt. I personally use the client as with a click of a button I can have the setup files downloaded to my iRacing setups folder and ready to go for the race. Adjusting a limited slip differential A very nice added bonus with VRS is that youll have access to all their telemetry software and logging data. One of these tools is car setup. Thus, having a basic understanding of car setups becomes a very useful asset in your sim racing career. If your camber has changed, change it back to the old (desired) value. Use the delta-bar to keep track of time gained or lost in individual corners. Head on to 5.2 where we focus on tyres. 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. DLM Limited: 2/27/2023. The downloadable client that Craigs Setup Shop offers as well is really nice, mainly because Im lazy, but also because it keeps everything organized and is fast. In terms of handling, this causes understeer when decelerating, and oversteer when accelerating. An iRacing membership provides entry into the newest form of motorsport: internet racing. Before I got out of the rookies, I could work my way up from the back and end up winning against all but the very best people on this track -- all against people who were keeping their gas pedal planted just like I was. 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. Especially at the top level of sim racing, setups are seen as highly guarded intellectual property. However, the ARB is essentially a torsion spring which stores some of the energy when twisted, so not the entire movement of one tire is transferred to the other. Dirt StreetStock: 2/27/2023. You want to start with changing the number of plates to control how quickly the differential builds up locking force. Each time you make a change to ride heights you should remember to also take a look at camber and toe. Camber & toe: As already discussed, camber and toe adjustments may affect the ride height. Observe the car and check your laptimes. A stiffer rear ARB causes more of the lateral load transfer to be distributed to the rear axle. Coming off the high side of the banking gives you a little run if you do it right, but its very easy to get loose doing this, so it comes with a risk. I just got a wheel and iracing this week. 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. This is because the mass of the chassis is not willing to change direction, while the tyres that grip to the surface are. If someone gets under me or if they are above me and they look sketchy, ill back out and let them by. In contrast, with the two springs at the rear of the car, roll stiffness is influenced by both the adjustable rear ARB and the rear springs. An extremely popular service, Virtual Racing School (commonly referred to online as simple VRS) provides professional setups for all official series on iRacing. The next track in the series is all about braking points and slip angle. How to Open the Setups The differential (or diff, for short) allows the left and right wheels to rotate independently, which helps balance the car through corners. You can view and compare different packs here. I went through a hole that looked clear, but I still got a 4x out of it, yet no damage or collision sounds/effects. 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. Nummer 6 - 2017; Nummer 5 - 2017; Nummer 4 - 2017; Nummer 3 - 2017; Nummer 2 - 2017 The less fuel in the tank the tighter the chassis will become. 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. The circuit has fast corners and fast straights, so a compromise is needed between the two baselines suggested above. After the tyre pressures, which we handled in 5.2, another significant setting to tweak on the Skip Barber is the anti-roll bar (ARB) in the rear. Thats exactly how I do it as Im already paying for Amazon Prime. Travel to Japan, Australia, and the USA with Fuji International Speedway, Sandown International Motor Raceway, and Port Royal Speedway. A spool gives you good traction accelerating on a straight line, but the handling of the car is compromised during turning. Necessary cookies are absolutely essential for the website to function properly. It is characteristic of a monoshock that the front spring has no effect on roll-stiffness. For example, a bumpy slow track like Sebring could need softer springs. You may want to adjust the ride heights to avoid bottoming out on bumps and curbs. You may have to take this into consideration when determining the static ride heights with a full tank. Use the baseline setup, and drive a few laps to get the heat into the tyres. The open diff also allows more torque to be transferred towards the less loaded tire. 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. . DIRT STREET STOCK SETUPS. Typically, its best to keep a note of the target ride heights as they are in the qualifying setup and try to resemble those as close as possible on the race setup. It is mandatory to procure user consent prior to running these cookies on your website. Explains how to select adjustments that may address the car's deficiencies in the beginning, middle and end of a corner. You are using an out of date browser. The iRacing Forums come in at last for me as theyre just inconvenient and unpredictable. If its worse and/or slower, go back to the original setting and then lower the pressure.

Unlike downforce, this is highly relevant for the Skippy. Continuing our example, lets assume that due to lateral load transfer the vertical load on the left tyre becomes 500 kg, while the load on the right side becomes 300 kg. Quick View. Splash = 2-3 gallons, 1/2 can = 5-6 gallons, 1 can = 11-12 gallons, 1 1/2 cans = 17-18 gallons, 2 cans = full tank. Press question mark to learn the rest of the keyboard shortcuts. 30 iRacing datapacks (setups, replays, telemetry) now on VRS Posted on August 13, 2017 by Jaap Grolleman Updates Each VRS datapack consists of data from all relevant iRacing circuits with a setup, telemetry and a replay file from Pro drivers in the current season (Season 3, 2017). Setting up a car is about trade-offs within the limits of physics. 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. For example, softer springs will compress more on the straights, as higher speeds generate more downforce. Street Stock setups. Lets get to know the suspension layout for the FR2.0. Yet a bigger contact patch also increases the rolling resistance of the car. The most common type of spring used in race cars is the coil spring, which is typically installed together with a damper (see picture). $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.
