1 Tyres

1.1 Ideal running pressures: 26 psi, all tyres/compounds.

1.2 Ideal running temperatures – within 10 degrees of:

  • 90 – Hypersofts
  • 95 – Ultrasofts
  • 100 – Supersofts
  • 105 – Softs
  • 110 – Mediums
  • 115 – Hards
  • 120 – Superhards


ACRL DRS App (v1.03, 815 downloads) The ACRL DRS app will be used to catch anyone who uses it when over a second behind the guy in front. The best way to use this app is simply to always wait for the BEEP & react quickly to the “angry” BEEPs you get when using DRS illegally. Make sure you have the correct drs.ini installed for each track.

4 ERS Guide

4.1 MGU-K Deployment Modes

  • Charging – Only used to save charge before a qualifying hotlap
  • Bal Low – Low charge usage, best for tracks with short straights/lots of corners
  • Bal Hi – As Bal Low but uses more charge, like Bal Low more effective at lower speeds
  • Linear – It’s a toned down “Hotlap” mode with balanced, medium energy usage
  • Top Speed – Low charge usage, high speed tracks
  • Overtake – High charge usage, high speed tracks – it’s Top Speed on steroids
  • Hotlap – Balanced but high energy usage throughout rev/speed range

Qualifying – Use hotlap on most tracks, but Spa will run out of allowed charge by Stavelot using Hotlap or Overtake modes.

Race – if in doubt, use Top Speed throughout the race and a dab of the KERS button when necessary. For those who want to manage charge and get the most out of it:-

  • Hi speed tracks – Switch between Overtake and Top Speed (use Bal Low if Top Speed won’t recharge)
  • Medium speed tracks – Bal Hi, Overtake, Linear and Top Speed are probably the best (use Top Speed to recharge or Bal Low if that fails).
  • Low speed tracks – Manage between Bal Low, Bal Hi, Linear and even Hotlap (use Top Speed if Bal Low won’t recharge)

4.2 MGU-K Recovery (Levels 0 – 10) Low levels give more stability under braking, but most people can cope in this car with the higher levels 7-10.

4.3 Engine Braking (Levels 0 – 13) This is a matter of preference. High values give you slightly better fuel consumption but make the rear less stable, low values are easier to manage but mean you are more likely to run through a corner as you release the brake pedal.

4.4 MGU-H Battery/Motor Mode Set this to “Motor” – end of, you should never need to use battery – one thing less to think about!

5. Changelog (physics):-

  • All compounds from 2018 season now available. Gaps in performance are even. Temps balanced front-back & running slightly cooler.
  • All grip curves regenerated as Trout League are convinced that Supers were glitched.
  • All compounds run best at 26 psi when hot. Tyre walls are softer to compensate for higher psi. Tyre blankets 90 degs not 80 degs.
  • Camber settings allowed from 0 now.
  • Handling is more balanced, more accessible. Brakes much more forgiving.
  • Top-end power is down, but mid-range is up (reduced turbo-lag). This car is a lot quicker than original.
  • DRS works properly & de-activates above 4G lateral force automatically.
  • Fuel heavier (car slightly lighter) – emphasises difference between full/empty tank in a more realistic manner.
  • Diffuser height is raised to stop it bottoming out in high-speed corners which caused random spin-outs.
  • Underside colliders lowered as it was clearing sausage kerbs completely before.
  • Tyre change/repair times sped up & fuelling slowed down for league purposes.
