How to make Vehicle Turning correctly?

I'm trying to make scripted car but I have trouble scripting Vehicle Turning. For example this is how I handle Turning Right

local UIS = game:GetService("UserInputService")
local part = script.Parent
--This are Three things I use For moving and Turning
local thruster = part.BodyThrust
local gyro = part.BodyGyro
local rotate = part.BodyAngularVelocity
-------
local on_move = part.OnMove

local R = 60



game:GetService("RunService").Stepped:Connect(function()




    --Resistance and Deaccelaration  
    part.Velocity = part.Velocity - part.Velocity/R



    local function onKeyPress(inputObject, gameProcessedEvent)


        --Forward
        if inputObject.KeyCode == Enum.KeyCode.T then
            on_move.Value = true
            direction = part.CFrame.LookVector


            gyro.CFrame = CFrame.Angles(direction.X/2,direction.Y/2,direction.Z/2)
        end
        --Backward
        if inputObject.KeyCode == Enum.keyCode.G then
            on_move.Value = true
            direction = part.CFrame.LookVector


            gyro.CFrame = CFrame.Angles(-(direction.X)/2,-(direction.Y)/2,-(direction.Z)/2)
        end
        --Turning Right
        if (inputObject.KeyCode == Enum.KeyCode.T and UIS:IsKeyDown(Enum.KeyCode.H)) or (inputObject.KeyCode == Enum.KeyCode.H and UIS:IsKeyDown(Enum.KeyCode.T)) then
            on_move.Value = true
            direction = part.CFrame.LookVector

            rotate.AngularVelocity = Vector3.new(0,-2,0)
            gyro.CFrame = CFrame.Angles(direction.X/2,direction.Y/2,direction.Z/2)

        end
        --Left
        if i(inputObject.KeyCode == Enum.KeyCode.T and UIS:IsKeyDown(Enum.KeyCode.F)) or (inputObject.KeyCode == Enum.KeyCode.F and UIS:IsKeyDown(Enum.KeyCode.T)) then
            on_move.Value = true
            direction = part.CFrame.LookVector
            rotate.AngularVelocity = Vector3.new(0,2,0)
            gyro.CFrame = CFrame.Angles(direction.X/2,direction.Y/2,direction.Z/2)

        end
    --




    end
-------Stop the  Car
    local function onKeyLetgo(inputObject, gameProcessedEvent)
        gyro.CFrame = CFrame.Angles(0,0,0)
        rotate.AngularVelocity = Vector3.new(0,0,0)
    end




    UIS.InputBegan:connect(onKeyPress)

    UIS.InputEnded:connect(onKeyLetgo)




end)

But it seems that Variable "Direction", Which is lookVector, isn't updated when BodyAngularVelocity Rotates The part. It updates when you Re-press keys.
