More Realistic Handling for a Car ( Not an A-Chassis )

[Sherlock_999ALT]

I have made a car for a racing game and want it to handle similar to cars in Roblox F1 games like Formula Apex or RFA.

‘Normal’ cars can make tighter turns when they are going slower. My car does this but not to the right extent. In games like Formula Apex, if you are going too fast on a tight corner, you will hit the wall. My car’s turn rate is very similar while going fast and slow.

Basically the problem is I want the cars to now always be going to top speed, but have lots of mobility while going slow like in Formula Apex

if you want to try the cars, use these links:

Hey,
You can divide the maximum turning radius by the speed at which you are moving, e.g. add 2 variables 1 is the speed to which the turning angle should fall and the second is the minimum value in % as long as the car can turn the wheels

I’ll try this today, thank you!
