Here is the progress of the mod in question

Day 1

I started with the basics, getting some references to start the dev of the mod.

Once i have enough information i started with the tyres dimensions and the wheel base to have a reference in the editor

Then start with the moddel in question

Day 2

Taking a rest between days and back to action with the model, this time making almost the entire model, leaving the wings for later

Modeling the car took me all day, once i finish it, i end up the day by ajusting the driver position and animation

Day 3

After a 5 days break, i came back fully charge and ready to continue

Starting with the wings, modeling them and adjusting them to match my references

Also making an primitive interior to continue with the textures.

Day 4

once i finish with the main model, i started adding and moddeling sub objs,

then adjusting the suspension to make them look better and not colliding with the main model.

as final extra for the day, Shaping the rims to a proper looking

Day 5

a day of final touches starting with the template

and then testing it out with a proper skin and adjusting the template

and thats it, a mod developed in 2 weeks resume in 5 days (mostly resting mentally)

To do list:

-Testing the aero and dirty air (Nerf if required)

-improve interior

-Create more skins

-think and add more chassis confgs (same as the F1 91 confgs)

-Do minor adjusts if needed

Improving interior, new textures and adding front brake ducts

Baking 2 more skins, during weekend ill do 2 or 3 more

Ive done 3 more skins, Now there are 6 skins in total to select
