Verification of 8-DOF electric vehicle in MATLAB based on real world data from CarMaker

Based on the verification, I have obtained similar graphs based on the values from both MATLAB and CarMaker. I am currently having some issues with the roll angle of the vehicle in MATLAB where it does not shows a reasonable plotting for double lane changing manoeuver. I will attatch the obtained graph along with the parameters. For your information, the blue plots represents data from CarMaker and yellow is the plotting of the 8-DOF model in MATLAB.

data.g = 9.81; % [m/s^2] acceleration of gravity

data.f_res = 1.1e-2; % [-] rolling friction parameter

data.k_res = 6.5e-7; % [s^2/m^2] rolling friction coefficient

data.rho = 1.205; % [kg/m^3] air density

data.area = 2.156; % [m^2] cross section

data.cx = 0.30; % [-] drag coefficient

data.mass = 2200.10; % [kg] total vehicle mass

data.Jx = 552.75; % [kg*m^2] roll-axis inertia

data.Jz = 3002.5; % [kg*m^2] yaw-axis inertia

data.Jw = 2; % [kg*m^2] spin-axis inertia of wheel

data.radius = 0.3401; % [m] wheel radius

% Pacejka 5.2 tyre model data

tyre = ImportTyreData('.', 'Tyre_VSM.tir');

tyre = rmfield(tyre, 'file');

data.tyre_par_full = tyre;

data.wbase_f = 1.4727; % [m] front wheelbase

data.wbase_r = 1.4553; % [m] rear wheelbase

data.wbase = data.wbase_f + data.wbase_r; % [m] wheelbase

data.track = 1.655; % [m] track

data.h_cg = 0.631; % [m] centre of gravity height from ground

data.h_roll = 0.091; % [m] roll centre height from ground

data.k_roll_f = 8.67e4; % [Nm] roll stiffness at front

data.k_roll_r = 7.80e4; % [Nm] roll stiffness at rear

data.c_roll_f = 1.2e6; % [Nm/s] roll damping at front

data.c_roll_r = 6e5; % [Nm/s] roll damping at rear

data.k_act_roll = 0.9; % [-] active anti-roll coefficient

Amazing and something very interesting to learn
It would be amazing if you could guide me how should i implement it to the vehicle
