AST Lowering Springs For BMW Z3 1.9 09/1999-2002, Front 30 , Rear 30

The AST Lowering Springs for BMW Z3 1.9 (09/1999-2002) represent a high-quality solution designed to enhance your vehicle's handling and aesthetic appeal by lowering its center of gravity. Manufactured with precision using advanced Wafios coiling machines, these springs deliver consistent performance and durability. The set includes front and rear springs, each providing a 30 mm drop, carefully calibrated to maintain a balance between sportiness and comfort.

Engineered specifically for the BMW Z3 1.9 model years 1999 to 2002, these springs serve as a direct replacement for the original equipment manufacturer (OEM) springs. Their progressive coil design ensures improved road grip and stability without compromising the ride quality you expect from your vehicle. Crafted from premium materials, the AST springs undergo rigorous cold-coiling processes to guarantee longevity and resistance to fatigue.

In addition to enhancing handling characteristics, the lowered stance provided by these springs contributes to a more aggressive and refined appearance. The design philosophy behind AST springs emphasizes both performance and reliability, making them an ideal choice for drivers seeking subtle yet effective suspension upgrades. Backed by a lifetime warranty against breaking, these springs offer peace of mind and confidence in their structural integrity.

Please note that these springs are not compatible with models equipped with the EDC system. Additionally, the rear spring design changed in early 1999 due to the introduction of a heavy-duty 6-cylinder rear axle on 4-cylinder models, which is an important consideration when selecting the correct components.
