@prince_linus @gdfGDS44 beta link posted if you want to test it

As promised before, here is a link to the latest in what I have been working on for both handling and sound swap as a sort of beta test, though still not done with the remaining vehicles. Need to retune sedans and finish the XA21 and zorusso supercars in addition to vans, SUV and some others down the list.
Note: files do not have any install instruction as of yet since it's not a release. Test if you know where each file go. Will make an instruction Readme when the main version releases. Let me know if there are install difficulties and bugs for crashes and such. Any gameconfig that supports latest version should work.

@gdfGDS44 Still working on it (~5-10 vehicles per day, taking roughly 2-4 hrs per day), and Rockstar updating delayed things further... No eta just yet, but almost done going through the list. Did improve workflow by reducing the number of benchmark parameters, like lap time testing, but re-tuning a lot of vehicles due to the integration of gear ratios and suspension tuning seem to take the most time. Should be done soon hopefully...

@prince_linus can't promise, but most suspension are near stock level, with the exception of offroad (spent quite a bit of time tuning suspension for offroad vehicles, particularly rallycars)and maybe some SUV, but there are clipping through fenders in an effort to increase suspension travel.

Progress update:
Almost done going through supercars, only SUVs, utility, and vans left I think.

Progress update:
Phase 2 has been completed for awhile now, at phase 3 going down the list, just finished motorcycles and at muscle cars now. As expected, it will take awhile before everything has been rechecked, so probably won’t be able to make it before December. Will probably finish just the 1/4 mile times and top speed, then just do track testing afterwards for more finetuning, to speed things up at least.
As far as beta testing goes, not really ready for it yet as lots of things have been changed and needs testing with data. Will probably release it here for feedback once its ready, so I guess not really a beta anymore.

Hi all,
After a long, sudden hiatus from the game, an update is finally in the works.
The hiatus came about due to life and partly cause was kind of burned out from it all, especially testing the helicopter physics...
Anyways, since I came back around to updating it, sort of changed how I work on this, to be more structured and organized, and hopefully more efficient, with various phases shown below:

Phase 1: Research and enter preliminary meta values and calculate gear ratios based in-gear speed and real life gear ratios.

Phase 2: Fine tune said metas in-game and how its performance (grip, acceleration, top speed, etc.) is relative to other vehicles in the same class using lap timer tool on the long track and the Nurburgring GP mostly. Also change vehicle sounds for ultimate sound swap if necessary.

Phase 3: Run through a fine tune/fix all previous vehicles (including helis and planes) going through each vehicle class (probably will be the most time consuming...) and maybe setup an excel sheet showing all the lap times and 1/4 mile times for all land base vehicles. Also, will try to complete the database for gear ratios with links to reference vehicle as done with all the casino and summer dlc vehicles so far (time consuming...). Finally, perform a quick check how they perform in streets using a street course.

Phase 4: Simply drive around the city to see how the AI deals with handling then its ready for release.

So far reverted all helicopters back to pre-5.0.
With the newly added vehicles, Phase 1 is complete, now at Phase 2, just finished the open wheelers, so still a long way before release, so hopefully I don’t feel burned out again...

As for the crashing that some people are experiencing, I haven’t experience any yet during any of my builds. If it crashes due to an error/typo in the values, it would crash immediately, so that isn’t the case (trust me, had that before). I suspect its probably cause the meta file is rather large with all vehicles in 1 file, perhaps exceeding some values set in the gameconfig by Rockstar, so downloading a robust gameconfig is probably necessary. Been using dilapidated’s gameconfig without problems, so is the one I’d recommend. Be sure to use all recommended memory mods and use the edits pinned in the comment section.

This primarily a solo project and since I only have vehicles I’ve owned and racing sims to reference from, some vehicles may not feel as appropriate as it should...

However, I wouldn’t mind sending my edits to those who wants to “beta” test the latest changes, as feedback would be very useful to isolate any bugs or perhaps change the “feel” of some vehicles for those who own them in the style of this mod for any specific vehicles. So feel free to let me know if you want to try the latest build and let me know of your thoughts.

No solid ETA yet, but will update this page as more progress is made. Hoping to be done before end of November, but will see...

Progress update:

• Finally uploaded V5.1 as a "beta" version because I could not sort out the few helicopter that wouldn't fly properly, along with a plethora of other changes.
• This "beta" version is so I can receive some constructive feedback and perhaps a solution to some problems.

Below is the update log:

V5.1:

• Numerous bug fixes as a result from V5.01a.
• Small changes in grip, especially with braking distances to give the AI, with their limited detection field, a boost while still keeping the distance somewhat believable.
• Re-tweaked shifting characteristics and engine inertia of each vehicle to accomodate ikt's new update of the Manual Transmission mod which now relies on the clutch speed for both up and down shifts.
• Re-tweaked suspension for SUVs and offroaders.
• Re-tweaked some anti-roll bar biases and settings for certain vehicles for better driving dynamics.
• Re-tweaked suspension for better ride height and suspension travel in many vehicles to react more realistically.
  • This is a request by prince_linus and he has won me over, since the tweaked vehicles ride better and looks better (especially some cars with a lot of negative camber)
  • As a result of this re-adjustment, some vehicles will have their wheels clip the fenders, but the alignment introduced in this version help alleviate the clippings somewhat.
• Added proper wheel alignment (camber, toe, castor, etc.) to all vehicles with 2 wheels per axle (essentially all cars and trucks, 417 vehicles total)
  • Looks especially good on racecars and supercars, like the Tyrant or the LE-7B, plus classic sportscars such as the Savestra or Turismo2.
• Re-worked motorbikes and some planes to be more manageable.
• Added better transmission and gear ratios for trucks and other vehicles.
• Overhauled helicopters to behave more like battlefield games.
  • The Akula, Hunter, and Valkyrie1 are bugged, so AI have a difficult time piloting it, but can be managed by the player.
    • This is the reason why V5.1 is essentially a beta until the helicopters are sorted out, so if you find a fix, please let me know and I will credit you for the fix.

The update is more or less finished, but the Akula, Hunter and Valkyrie are bugged and I cannot seem to fix it yet atm, so will probably release what I have now and fix the bug at a later update. Surprisingly, the MOD 0 Valkyrie is not bugged, only the regular one is.

After a few more changes and testing, I will upload the update.

Finally found a way significantly overhaul all helicopters to handle/feel somewhat similar to the Battlefield games.

This means:

• no more fixed axis/tilt limit found in the vanilla game
• pilots now have much more control of the helicopter
• you can finally fly upside down and perform tricks like front-flips, back-flips, side-flips, etc.
• With the removal of the fixed axis, you now have a much more accurate and realistic helicopter aiming and shooting (like the Battlefield games)

Currently still in beta phase and testing, but should be released shortly as V5.1 for my handling mod, along with other tweaks with suspension height and plane optimizations.

Will post a video of what I mean once it's ready.
