Lowered ride height and less body roll for now. Maybe racing in the future, though I'll be so busy it may be twice a year. The Lanos, though it handles inherently well (thanks Porsche and Opel) has abysmal springs. Driving it straight over uneven pavement, the car bumps so much you'd think it had a stiff purely race suspension, but take it around a corner with even mild devious intent, the horizon turns sideways and the leather seats slide you to the point that your ass might touch the window. Its the exact opposite of what good springs should be.
If you were gonna suggest coilovers, its useless, they don't exist. At all.
