ACS DSR Drag Mod

The DSR drag mod are replacement root prim scripts that convert the system into a drag-racing only configuration. Menus differ from the standard ACS menu to reflect the unique needs of drag racing system. The DSR mod has undergone considerable amount of beta testing and has been winning quite a few races, and now is ready for release to the entire Script Owner's Group.

The drag racing transmission has four customizable gears;

  • reverse
  • 1) return,
  • 2) staging
  • 3) drag

The current drag racing gear can be stored in one of 12 class power presets, changeable from the >Gearset menu.

Since each vehicle build is different, you will need to carefully adjust your drag gear to fit your vehicle build for the intended class of drag racing.

Return gear is your standard pit return speed gear, and staging is for gently staging the vehicle at the starting line. Switching into drag gear will auto race-align the vehicle.

The vehicle is shifted using the E/C or PageUp/PageDown keys only. SHIFT+Left Arrow or SHIFT+Right Arrow will scoot the vehicle sideways slightly for precise starting line positioning. Standard key controls are retained for the recover function but there is no flight mode in this mod.

By default, gear 1 (return gear) is faster than gear 2 (staging), but you can easily change the gear powers for reverse through staging from the >Controls menu, where you can also name the current class.

The DSR system is intended for HUD-Free usage, with the engine rev function added to the main menu, though you can still use the driver HUD as well. Record position and return position have also been placed on the main vehicle menu for easy access and HUD-free operation.

The drag mode will work in cars or motorcycles, but does not bank motorcycles on turns as there are (usually) no turns in drag racing.


Like with other ACS mod packs (knife, Mariner, Drifter you simply swap out your existing ACS root prim scripts for the ones required for the mod. The drag mod replaces the Engine, Root Settings, Root Menu and Root Tools and uses your standard Root Sit (You must add your Root Sit script and an animation to the vehicle root). Don't forget to set the permissions on the scripts and reboot the vehicle!

The Root Settings and Root Menu remain full permission for your customization but permissions must be correctly set ton copy only before they will operate.

While the vehicle is designed to be completely customizable via the menu system, you can pre-set the default class powers and names directly in the script at the top of the Root Settings DSR script:

Q: Can I make my vehicle switch between Drag mode and regular mode?

A: The reason the system is a complete replacement and not an option for the regular ACS engine, is a matter of keeping the minimum scripts in the vehicle. Many drag and other racing tracks have a strict script limit for vehicles to prevent lag. So while the scripts could be set up to switch between multiple different engines and configurations; this is not a desirable script load for vehicles and is the reason for separate replacement mods. If you wish to provide your vehicle customers with a drag version of the vehicle they have purchased, you could include a separate drag version with their package.
