Eibach 9310.140 Drag-Launch Springs Features:

• Designed to optimize weight transfer—stores energy in the front end and plants it in the rear for dead-hook launches
• Factory‑tested on original dampers, this kit delivers strong launches and reduced 1/4‑mile ETs without sacrificing street comfort
• Includes a helper airbag for the right rear spring—tweak launch bias for different tire setups and track conditions
• Maintains near‑stock ride height while improving launch grip—no drastic changes to stance
