These are the ranges for spring rates I usually operate (given in percentage of distributed front / rear weight) on RWD cars:įor FWD cars simply swap front and rear spring rates. ![]() As with ARBs this is not a simple 1:1 distribution according to weight distribution as for instance the drive wheels are usually run with lower springs rates in relation to non driven wheels to reduce wheel spin.Īs others suggested a good range is between 1/3 and 1/2 of the slider though there are exceptions where you need to run above or below that range. More weight requires stiffer springs and more flexible chassis / suspension require higher spring rates on the non driven wheels (front for RWD) and lower spring rates on driven wheels (rear for RWD).ĭistribution of front and rear spring rates is related to weight distribution, so cars with more front weight will require also higher front spring rates. Spring rates need to be setup in relation to car weight, weight distribution and chassis / suspension stiffness. Stiffer springs provide more control but can lead to harsh unpredictable car behaviour during directional changes or wheel spin when accelerating when setup too stiff. Springs control the weight transition during directional changes and between front and rear wheels during acceleration and braking. Softer springs provide more grip but can lead to sluggish car behaviour during directional changes or locking front wheels under braking and when setup too soft. Older cars and muscle cars require higher spread (>1 per 1%) while race cars require lower spread. for 51% front weight distribution the front ARB should be 1 higher than the rear ARB. This is however not as simple as 1:1 distribution according to weight distribution because springs and dampers also affect car balance during turning.Ī good starting point for ARB distribution for RWD cars is 1 per 1% weight distribution difference to 50%, i.e. race cars).įront and rear ARB distribution has a relation to weight distribution, so in general a car with more front weight should have also higher front ARBs than rear. ![]() Decrease ARBs for cars with less weight and / or more rigid chassis (e.g. Increase ARBs for cars with more weight and / or less rigid chassis (e.g. Likewise the less the car weights the lower the ARBs can be set.Ģ0/20 is good middle ground for modern road cars around 3000lbs and 50% weight distribution and corresponds to an ARB stiffness of around 63%. the more rigid the chassis is the lower the ARBs can be set. Generally ARBs need to be setup in relation to chassis stiffness and vehicle weight, i.e. ![]() Stiff ARBs provide more control during cornering but can result into harsh and unpredictable car behaviour when setup too stiff. Soft ARBs provide more grip during cornering but can result into sluggish car behaviour when setup too soft. Stiffer ARBs reduce body roll and thus provide less weight shifting during cornering. Softer ARBs create more body roll leading to more weight shifting to the outer wheels. Having different tire pressures on front and rear tires creates over- or understeer effects and is only required when tuning for speed, grip or specific tracks.Īnti-roll bars (ARBs) control the weight transition between left and right (or inner and outer) wheels during cornering. Generally front and rear tire pressures should be the same. Off-road tires generally require lower tire pressures than street, sport or race compounds for best performance.Ĭhanged in Horizon 5 Tire pressure tuning in Horizon 5 has changed since Horizon 5 takes place in a much warmer region than Horizon 4, therefore tire pressures generally need to be increased by 3 psi as compared to Horizon 4 for best performance. Increased tire pressure compensates for lower level of rigidity of softer compounds. Softer tire compounds like Sport or Race compound provide more grip but also have less rigidity than Stock or Street compound. Reasoning for that is that besides grip tires also provide a basic level of rigidity and therefore control. ![]() The general rule here is the softer the tire compound the higher tire pressure is required. Tire pressure tuning first and foremost depends on the used tire compound. ![]()
