Setup tips

[spanner]

This are taken from a copy of the starmazda setup guide i found on iRacing forum that someone created. However i have found it to be quite useful, especially in AC and thought i'd post it up here. So now my default tweaks to any setup are to increase rear rebound and then try reducing front rebound or increase front bump. In R3E i find i have to drop the rear ARB right down as well as i find it make it a little unpredictable. If i need more turn-in i'd increase rear springs.


Troubleshooting Guide

Too Slow On Straightaways
•   Lower both front and rear wings
•   Make the front and rear ride height the same

Hitting the Rev Limiter On Straightaways
•   Switch to taller gears

Back End “Swims” Under Hard Braking
•   Move brake bias toward the front

Front Brakes Lock Up Under Hard Braking
•   Move brake bias towards the rear

Damn Thing Won't Turn-In (major understeer)
•   Move the brake bias towards the rear  [changed the order, most likely fixes first]
•   Use a softer front ARB or firmer rear ARB
•   Use a softer front spring or stiffer rear spring
•   Raise rear tire pressure or reduce front tire pressure

Won't Turn-In Quickly Enough (minor understeer)
•   Reduce the front bumps or increase the rear rebounds
•   Decrease front toe-in (increase toe-out)

Back End Slips A Little on Turn-In (minor oversteer)
•   Increase the front bumps or decrease the rear rebounds
•   Increase front toe-in

Snap-Spins On Turn-In (major oversteer)
•   Move the brake bias towards the front [changed the order, most likely fixes first]
•   Use a firmer front ARB or softer rear ARB
•   Use a stiffer front spring or softer rear spring
•   Reduce rear tire pressure or increase front tire pressure

Will Not Turn in Mid-Corner (major understeer)
•   Increase front wing or decrease rear wing
 
•   Use a stiffer rear spring or softer front spring
•   Use a firmer rear ARB or softer front ARB

Front Tires Push in Mid-Corner (minor understeer)
•   Decrease rear wing or increase front wing
•   Decrease front ride height or increase rear ride height

Back-End Starts to Slide in Mid-Corner (minor oversteer)
•   Increase rear wing or decrease front wing
•   Increase front ride height or decrease rear ride height

Spins in Mid-Corner (major oversteer)
•   Increase rear wing or decrease front wing
•   Use a stiffer front spring or softer rear spring
•   Use a firmer front ARB or softer rear ARB

Plows straight ahead on Corner Exit Throttle-On (major understeer)
•   Softer front springs / stiffer rear springs
•   Softer front ARB / stiffer front ARB

Understeering on Corner Exit Throttle-On (minor understeer)
•   Decrease front rebounds or increase rear bumps
•   Increase rear toe-in (more positive toe)

Oversteering on Corner Exit Throttle-On (minor oversteer)
•   Increase front rebounds or decrease rear bumps
•   Decrease rear toe-in (less negative toe)

Spins on Corner Exit Throttle-On (major oversteer)
•   Softer rear springs / stiffer front springs
•   Softer rear ARB / stiffer front ARB

Hi Mark...
Thanks for the setup guide...
will print this and start looking into it more detailed..

Bump

Thx, very usefull and handy.


One question: i thought for the brake bias for heavy turns push the BB forwards and for light turns bring the BB more to the rear.

Example now for Silverstone: on Wellington straight i change the BB 2 clicks towards the front for Brooklands,Cops,Magets,.... up to Stowe, then just for the Vale chicane i change the BB again 2 clicks towards the rear (need no braking for Abbey and Village, and the Loop arena is again heavy braking).

Now i looked towards a track guide video in the F1 of Rosberg, he suggest also to change the BB at those 2 points on the circuit. But he is doing the opposite. Just before Brooklands BB towards the front and before Vale towards the rear.

  Confused now  my idea works for me heavy braking i prevent locking of the front tires with BB towards the rear. And in light turns where i wan't a stable car for trail braking BB towards the front (if i forget to change the BB in a lap, i have oversteer in brooklands)

Need i need to change my approach
