YouTube, there is software to help you with that as well. Travel to Japan, Australia, and the USA with Fuji International Speedway, Sandown International Motor Raceway, and Port Royal Speedway. Stiffer rear springs give you a more consistent handling through the corners, while softer rear springs will give less drag on the straights. This is quite unfavorable when one tire is on a slippery surface like mud, grass, ice or wet track markings, as the tire on the slippery surface will end up spinning, consuming most of the available engine torque. Try fiddling with the spring rates, and see if you can improve your laptime with it. Press question mark to learn the rest of the keyboard shortcuts. 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. Each car is different, but in general theres an ideal ride height range that produces maximum downforce. The ARB connects the suspension elements of two wheels on the same axle. We use this cookie to see what our users do after they click on an ad. This series is Fixed Setup. 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. An even lower tyre pressure will cause the shoulders of the tyre to bare the grunt of the load, less than ideal (see illustration). By statically and/or dynamically adjusting the ride heights, you can optimize the aero performance of the car. Stiffer springs will reduce body roll. I dont want to have to waste my time searching pages and pages of posts to try and potentially find a setup that someone has posted, only to do the same thing again a week later. Together, they make a good introduction -- which is all they really are to begin with. S3 - Street Stock - USA $4.00 S3 - Street Stock - Lanier $4.00 S3 - Street Stock - Southern National $4.00 S3 - Street Stock - Legends Oval $4.00 S3 - Street Stock - North Wilkesboro $4.00 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. Id really only recommend this tier if you only race one very specific car and you dont plan on racing anything else. Modify the suspension geometry so that you achieve the new desired camber (or toe) at that same ride height. 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. iRacing Fixed Steering Wheel Setup Steering wheel setup adjustments in the iRacing garage and option menus that frequently get overlooked especially when using fixed setups. You must log in or register to post here. Excessive front toe in will make a car turn into a corner quicker, & may create a loose condition. 3: Ground clearance So far I've had 1 incident in each race, one of which I don't see how I could have avoided. The higher you place in the race, the cleaner the competitor's you'll race against going forward, making it even easier to gain safety rating. One of the most common setup scenarios is converting a qualifying setup to a race set. The closest I've come to actual racing was in the last race. Less fuel equals faster speeds. Internet racing is a fun, easy, and inexpensive way for race fan and gamers alike to enjoy the thrill of the racetrack from the comfort of their home. Spools are typically used in karts, drag racecars, some oval race cars and some road race cars. 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. The long and short of it is this. Limited slip differential Aerodynamics will cause the ride height to change. Open to Class C Oval drivers and above. With the turns so gentle and banked, you can almost lay a brick on the gas and take a nap. Privacy Policy | Applying it to the FR2.0 Finally, well look at a high-end, high-downforce car in the HPD ARX-01c. This can improve the balance of the car, and increase overall grip on the axle as shown in the earlier example. In addition, the balance changes suddenly through the corner, which is not desirable for a race car, as you are giving up traction. If you ask too little, you wont notice any difference in handling. If not, then your biggest gains might not come from setups. Save these setup files to C:\Documents\iRacing\setups\streetstock\. If there are more than 9 iRacing setups available for this car/track combination, look for the navigation links near the bottom of the page. Spring rates: Stiffer springs raise the car, softer springs bring it closer to the ground. Finding the balance So, finding the optimal spring rate is a matter of finding the right trade-off between the above effects, which is often a compromise. The open diff also allows more torque to be transferred towards the less loaded tire. iRacing 2022 Season 3 has arrived! 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). 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. Thats exactly how I do it as Im already paying for Amazon Prime.

With datapacks, you can easily compare your own racing and consequently improve. Welcome to the Unofficial iRacing Reddit Community. Moreover, lower tyre pressures also affect the lateral stiffness, and when running very low pressures, its possible that the middle of the tyre is no longer at the centre of the rim while cornering. Gaining proficiency in car setup is a process that requires you to experiment and analyze a lot. It is characteristic of a monoshock that the front spring has no effect on roll-stiffness. 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. Rookie Street Stock - Charlotte - Tutorial - YouTube 0:00 / 4:01 Rookie Street Stock - Charlotte - Tutorial 18,350 views Feb 11, 2017 The replay and telemetry data pack can be found. VRS offers three different subscription plans. This is a topic for another article, but it is a very nice software that you can use to see exactly where youre losing time and compare your laps to the pros, down to the millisecond. 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. So, running low pressures has its drawbacks, as does having too high a pressure. the BMW Z4 GT3 has its tank fairly far back in the car), setting the race fuel ride heights could be trickier. I would definitely suggest that you check out Setups4i.Racing over the iRacing forums if youre after a setup just to get you on the road as quickly as possible. Lower tyre pressures lower the vertical stiffness, which in turn causes a bigger contact patch (flatter tyre), and in theory sounds promising. 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. That means that, if you have Amazon Prime and link it to your Twitch account then youll be able to use the free sub that you get with that on Craigs Twitch account and get the setup service for free. This may change your ride height again, so you may have to do a few iterations of ride height adjustment, camber adjustment, until you achieve the desired result. iRacing Asphalt Street Stock Setups for Southern National Speedway iRacing setups for the Asphalt Street Stock Car at Southern National Speedway are available on these pages. Adjust these properties until your achieve the desired measurement for ride height. Open differential Do not attempt to open the setup file in Windows. This guide defines each listing in the Garage section for each car available in the iRacing.com Motorsport Simulation. 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. Depending on the location of the ride height sensor (e.g. This causes stress (wear) on both tires and the drive train. Terms of Use | Such a setup would produce more rake (and downforce) in the slow corners and less drag on straights. For example, softer springs will compress more on the straights, as higher speeds generate more downforce. First race ever, I was in 9th going into the last corner. At a track with lots of high speed corners you may want to run higher pressures to increase grip in high-load situations. Later on, well also focus on temperature and weather differences. When adjusting ride heights Ride height (measured in mm or in) defines how far off the ground the chassis sits. Its important to note that tuning the ARB will only make a difference if you are utilizing the traction circle, as explained in 3.1. Observe the car and check your laptimes. You may want to adjust the ride heights to avoid bottoming out on bumps and curbs. For example, with stiffer springs, going over bumps and curbs may cause one or more tires to get momentarily unloaded or completely lose contact with the track, which would cause handling issues. It may not display this or other websites correctly. Keep in mind that many suspension elements are connected. Dynamic ride height is the actual ground clearance at any moment in time as the car goes around the track. A popular locking differential is the Detroit Locker, used in NASCAR. As a result, as soon as one wheel moves up or down, the other wheel is forced to follow that motion. Its measured in Newtons per millimeter (N/mm) or pounds per inch (lbf/in). 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. Continue with anti-roll bars, in 5.3. 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. A completely open differential allows the left and right tires to rotate entirely independently. Bring a 3.42 rookie it sucked soo bad getting here. iRacing Setup Sync is a platform created by Nick Thissen and contains a huge library of free iRacing setups. JavaScript is disabled.

Locking differential New members only. 2013 - 2023 Smarty Co. All rights reserved. In practice, you wouldnt make spring rate adjustments to affect roll-stiffness. With this we mean the bumpiness of the surface, and the lengths of the straights, and whether there are many fast or slow corners. Yet a bigger contact patch also increases the rolling resistance of the car. The dynamic ride height changes throughout a lap, for instance when a car goes over a curbstone, or when downforce compresses the springs. The iRacing Forums come in at last for me as theyre just inconvenient and unpredictable. 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. He feels that there is one race that , Wight only needed to finish fifteenth or better to beat out his teammate Billy Decker for the championship. We suggest you select a track, default weather and start a test session. As we saw, both a spool and an open diff have their issues, especially in racing conditions.

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. I encourage rookies to race to win, while learning to race clean. Virtual Racing School. 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. Significant changes to spring perch offset, or to pushrod length could also impact camber and toe. So, the inside is forced to rotate faster than it needs for the turn radius and hence spins. 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. Consequently, there may not be enough torque going to the tire on the grippy surface, so acceleration would suffer. It's just me or is this track not good for the car? 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).
