After I got Rogerab fixed to my Nexa Baleno Alpa Petrol and I took bumpy road with intent to test these and i could really feel the difference in driving the car. I Feel the suspension is more sturdy now. Will have to test on express highway road though to see if the rolling effect still persist. But overall satisfied with product and the installation process took 45mins. Staff are freindly and explaning the product als while installing the rogerrab Duo into the car
