Key Features:

H&R Sport Springs
H&R’s most popular springs, the Sport Springs lower your car approximately 1" front and rear for a sleek, performance-focused stance. Designed with a progressive spring rate, these springs reduce body roll, lower the center of gravity, and preserve ride comfort. They also reduce drag for a more streamlined profile and better fuel economy.

Bilstein B8 Performance Plus Dampers
These premium monotube dampers are valved specifically for lowered vehicles and are the perfect match for the included H&R springs. With Bilstein’s world-renowned quality and durability, they deliver improved damping control, sharper handling, and a more planted ride on both street and track.

Whiteline Caster/Camber Offset Front Strut Mounts
Fine-tune your suspension geometry with Whiteline’s precision-engineered offset mounts. These allow for additional +0.75° of caster and -0.5° of camber—ideal for dialing in alignment settings for improved cornering, directional stability, and tire wear. Constructed with durable low-compliance rubber and corrosion-resistant E-Coating.
