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. Street Stock Setups Filter by. 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. Matching front and rear ride heights may be all you need to convert a qualifying setup to a race setup. This can improve the balance of the car, and increase overall grip on the axle as shown in the earlier example. I just got a wheel and iracing this week. iRacing Forum. This basically just lets us know you are interested in iRacing! YouTube, there is software to help you with that as well. To make the chunks of information a little smaller and easier to digest, this is split into the multiple posts. I was following the leader for about 15 laps within .5 seconds, and within .2 seconds for about 8 or 9 laps. The setups come from a wide range of sources across the iRacing community, meaning the quality of setup isn't always guaranteed like it is with professional paid setups. This causes stress (wear) on both tires and the drive train. This helps with turning. 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. Learn how to make the proper adjustments to improve lap times. Factors: Deflection, contact patch, vertical and lateral stiffness The Charlotte Motor Speedway built a new infield road course, designed specifically for NASCAR competition, in 2018. 30L. Id really only recommend this tier if you only race one very specific car and you dont plan on racing anything else.

Just when you need grip the most! Press question mark to learn the rest of the keyboard shortcuts. Limited slip differential Explains the function of each adjustment. Significant changes to spring perch offset, or to pushrod length could also impact camber and toe. Different simulators implement this differently, but in iRacing you cannot set the ride heights with one parameter. 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. This track humbled me a little bit, and it really drills in the need to learn the proper lines. In general, aim to run the stiffest springs that still allow you to go over bumps (if a curb is giving problems, you may not want to counter it through setups, but just avoid hitting it). This means you should already be a driver capable of in-the-moment. This simplifies the front spring rates setup. Setup Database Download This would allow you have a car with more consistent aero performance in all corners regardless of speed. Puredriving school. See also thePC & screens, and the summary. But before you start, here are few questions you should answer to ascertain whether diving into setups is the best use of your time: If you can answer all these questions with a definitive yes, then this guide is for you. Yoeri Gijsen; Feb 22, 2012; Replies: 1; Views: 17k; Replies 1 Views 17k. Repeat this step until the improvement stops or the car becomes worse again. With this we mean the bumpiness of the surface, and the lengths of the straights, and whether there are many fast or slow corners. Privacy Policy | Now we understand how an axle can lose grip under cornering, and is this precisely what causes handling issues. Observe the car and check your laptimes. The dynamic ride height changes throughout a lap, for instance when a car goes over a curbstone, or when downforce compresses the springs. However, with higher end cars, especially those with high amounts of downforce, finding the right tyre pressure becomes a little more complex. Travel to Japan, Australia, and the USA with Fuji International Speedway, Sandown International Motor Raceway, and Port Royal Speedway.

Just before the final corner in the dog leg, before the start/finish, two cars wreck in front of me and go into the wall. A spool ensures both left and right tires rotate at exactly the same speed. 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. As I said, they can be a good resource but they can also be very hit and miss and, personally, I would rather just go directly to a resource that I know Im going to get a quality setup each and every time. The differential (or diff, for short) allows the left and right wheels to rotate independently, which helps balance the car through corners. Lets get to know the suspension layout for the FR2.0. The ARB stiffness can also determine the lateral load transfer between the front and rear axles, even if a car only has one ARB, like the Skippy, which only has one on the rear. Lets work through an example, using the chart above. 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 cars where the gas tank is located far from the center of gravity of the car (e.g. As a result, youll get a non-zero reading even if the splitter bottoms out. Alright, this is the first of the free ones, and honestly, its kind of a pain in the ass. 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. Recent Reviews: Very Positive (26) All Reviews: Blurring the line between real and virtual motorsports. This effect is most noticeable on the McLaren MP4-30 or Williams FW31, as theyre running on wheels with very tall sidewalls relative to their width. Head on to 5.2 where we focus on tyres. How to Open the Setups In most cases the additional weight due to the added fuel is bringing the car out of tech, which means its too close to the ground and isnt legal to race.

Pick up a decent setup (from the forums or a VRS datapack) first and focus on driving style until you are able to turn competitive lap times in the chosen setup. 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. Login Learn more Loading. Load the setup in the iRacing simulation under Garage My Setups. Applying it to the FR2.0 This season includes the release of iRacing's first fully electric race car, the Porsche Mission R, a pair of new European Road Courses, Motorsport Arena Oschersleben and Rudskogen Motorsenter, and a new Dirt Oval, Lucas Oil Speedway. In practice, you wouldnt make spring rate adjustments to affect roll-stiffness. It utilizes nearly all of the 1.5 mile oval as well as newly built infield portion - thus the name Roval (Road/Oval). And in a later article well look more closely how to approach dynamic ride heights. In the rear are two separate spring and damper units. If you ask too much of the car (overall Gs), the ARB wont help. A popular locking differential is the Detroit Locker, used in NASCAR. Its also one of the most important things to get right on every single car. Adjusting a limited slip differential 0 . Bring a 3.42 rookie it sucked soo bad getting here. The FR 2.0 has more setup options available, including an important one, which will vary greatly between circuits: the selection of front and rear springs. Fuel load: Added fuel (per the example above, for full race distance as opposed to for qualifying) adds more weight to the car, which compresses the springs more, which reduces the ride heights. New members only. Side-by-side racing is just something you cant do in rookies. So, finding the optimal spring rate is a matter of finding the right trade-off between the above effects, which is often a compromise. As far as lines, I've got qualifying down to around 36.4, but I seem to be stuck. If not, then your biggest gains might not come from setups. For example, here are the differential settings for the McLaren MP-30: You can achieve identical handling with completely different diff builds/configurations. The next track in the series is all about braking points and slip angle. 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 Setups. Dynamic ride height is the actual ground clearance at any moment in time as the car goes around the track. Once you understand what ride heights are and what interactions ride heights have with suspension geometry, you need to spend a lot of time testing and experimenting with different settings in order to find out what works with each specific car. Thats exactly how I do it as Im already paying for Amazon Prime. 30 iRacing datapacks (setups, replays, telemetry) now on VRS.

Posted on 26 Feb in delores winans grandchildren. 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). You pick either baseline as a starting point, for example stiff front and soft rear. 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.

On the flip side, if you have deeply ingrained old bad driving habits, it may be more efficient for you to tune the setup to your driving style. 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. In addition, the balance changes suddenly through the corner, which is not desirable for a race car, as you are giving up traction. The same applies to each wheels toe-in. Excessive spin on the drive axle cause that axle to lose grip causing sudden oversteer (on RWD cars) or understeer (on FWD cars). In the following series of blog posts were trying to shed some light on the various hardware parts you need to have or for some parts should have. Share your setups in this forum with the rest of the community. One of the few setup options available to the Skip Barber car is the pressure in the tyres.

These cookies remember website preferences and generally improve the performance of the site for the user. 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. Customize your cookie preferences below. Consequently, there may not be enough torque going to the tire on the grippy surface, so acceleration would suffer. First of all, you need to understand what an ARB is and what it does to the car. 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. The process of finding a good tyre pressure, at least for short runs, is the same iterative process as with the lower end cars. 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. The only way to pass I've found is to wait for the guy ahead to make a mistake, but being close enough to capitalize on that mistake seems to be rather dangerous from watching the guys ahead of be get punted into the wall. I want to be able to just find a setup for the car I want to drive and know exactly where to find it. When adjusting ride heights 20L. If you find the car unwilling to turn, you can try stiffening the rear ARB. Similarly, there is an ideal ride height range that minimizes aero drag. Necessary cookies are absolutely essential for the website to function properly. Each car is different, but in general theres an ideal ride height range that produces maximum downforce. Use the delta-bar to keep track of time gained or lost in individual corners. When the available grip of the rear tyres is exceeded first, the car goes into oversteer; when the grip of the front tyres is exceeded first, the car goes into understeer. You may want to adjust the ride heights to avoid bottoming out on bumps and curbs. 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). Finding the balance For example, a bumpy slow track like Sebring could need softer springs. You may have to take this into consideration when determining the static ride heights with a full tank. So while the total load on the axle remains the same (800kg), the total available grip is now only 955 kg. Conversely, softening the rear ARB increases available grip at the back while decreasing it at the front, hence, making the car less oversteery and more understeery. You also have the option to opt-out of these cookies. Also wasn't helped by the 20 laps I turned in testing where the car wouldn't break 120mph, so I say "wow, this is stupidly easy, you can't screw up" and join a practice session and all of a sudden I'm doing 140 running the same line You should be able to run the whole track without lifting off the gas. It also has a very active Discord server where you can discuss sim racing and get notified about new setups, etc. Setting up a car is about trade-offs within the limits of physics.
