In GTA SA, I was always embarrassed by the fact that, although there are good wheel models in the game, many cars use rather ugly wheels (and the most rubbish was deliberately put into tuning wheels, which discourages the desire to customize a car). I decided to fix it.
Now vanilla vehicles will sparkle with new colors, and tuning shops will have plenty to choose from. In addition, I have fixed many shortcomings of the standard transport: vehicles like the Buffalo or Sultan will no longer have an excessively high suspension, and some trucks have added double rear wheels, or the width of the standard ones has been increased. Also, some vehicles will have rear wheel drive instead of front wheel drive (eg Jester), and the tank will have more realistic mass and acceleration. In addition, in the installation instructions you will find a list of recommended mods that continue the theme of fixing and improving vanilla vehicles.
P.S. Have a good game!
