Product Description

The RS-R Super Down Springs (Part T284S) are performance-tuned lowering springs developed specifically for the 2001-2006 Lexus LS430 sedan with rear-wheel drive. These springs deliver a more aggressive drop compared to standard RS-R Down Sus springs, helping owners achieve a striking lowered stance while improving handling and reducing body roll. The Super Down design accounts for the LS430's factory suspension geometry, shock dampening characteristics, and spring rate to offer a balanced combination of ride comfort and performance enhancements.

Drop heights vary slightly between early (2001-2003) and later (2004-2006) model years, with more pronounced lowering on the earlier vehicles. Finished with a corrosion-resistant powder coat, these springs are built for long-term durability and a refined look. Ideal for LS430 owners seeking a sportier stance and improved road feel without resorting to coilovers, RS-R Super Down Springs provide a quality suspension upgrade tailored to your vehicle.
