ST lowering springs are performance-oriented springs designed to replace your car’s factory springs and lower ride height by about 30–35 mm for a sportier stance and sharper handling. They’re built from high-strength chrome-silicon steel with a durable epoxy finish, giving good longevity and resistance to corrosion. Lowering by ~30–35 mm reduces the centre of gravity, which helps cut body roll, improve turn-in response and create a more aggressive look, all while keeping daily usability relatively intact.
Key benefits (in brief):
Good choice if you want a visual + handling upgrade around a mild/moderate drop without going full coilovers.
