Eibach Pro-Kit Performance Lowering Springs
BMW M135 | i xDrive
The Eibach Pro-Kit for the BMW M135 (i xDrive) is a direct-fit performance lowering spring set that drops the ride height by 30 mm front / 15 mm rear, sharpening handling and closing the fender gap without touching your factory dampers. It carries full Part Type Approval (PTA) homologation (part no. 10-20-047-03-22), so the fitment is engineering-verified, not a generic guess.
