Performance Suspension Cup Kit - Sport - E39

Product Details

When upgrading a chassis, pairing lowered springs with factory length shocks is a compromise that leads to damper failure and floaty rebound. Turner Motorsport has curated this high performance suspension package to fix factory slop and deliver predictable turn in.

This kit matches progressive H&R Sport Springs with high pressure Bilstein B8 Performance Plus Gas Dampers. Because the B8 features a internally shortened piston rod, it pre loads the H&R spring correctly keeping the damper in its intended stroke range, eliminating spring play at full extension, and dramatically increasing stability during high G cornering.

Performance Benefits:

• Bilstein B8 struts use a shortened piston rod designed specifically for lowering springs, preventing premature bump stop engagement and maintaining proper suspension articulation.

• Resists oil foaming under aggressive driving, delivering consistent damper valving on track days and spirited canyon runs.

• Lowers center of gravity to minimize pitch, dive, and lateral roll, allowing you to carry more speed through the apex.

• Replaces sluggish factory float with instantaneous chassis response and enhanced road surface feedback.

Included Components:

• H&R Sport Spring Set

• Bilstein B8 Performance Plus Front Strut Assembly (x2)

• Bilstein B8 Performance Plus Rear Shock Absorbers (x2)
