Tein Street Advance Z Coilover Suspension Kit - Mazda3 Fastback BPFP HKS If you want to upgradeMuch like Tein Street Basis, Street Advance utilises a twin tube system and has adjustable lowering spring seats allowing you to adjust ride height. Unlike Street Basis, it also features adjustable damping force, allowing you to effectively change your handling characteristics. Compared to mono tube suspension, Street Basis is twin tube, meaning it attains a longer stroke with a smaller repulsive force, resulting in excellent high ride comfort.
