This is a brand new, highly sought-after Genuine OEM BMW Performance Package front suspension strut tower support upgrade set for a Z8. The kit features a matched pair of heavy-duty German-engineered steel shock tower guide supports stamped with factory part number 31330422175 (superseding production tracking reference 0422175). Originally engineered by BMW for high-stress applications on iconic specialty chassis like the BMW Z8 and the Alpina V8 Roadster, these steel reinforcement plates are widely utilized across the enthusiast community to strengthen the front shock tower housings against metal fatigue and structural deformation.

This comprehensive installation lot includes all corresponding factory hardware bags needed for a professional replacement setup. The structural update kit comes complete with a sealed bag of genuine BMW blind rivet flat-headed nuts (Part 07146989335), a dedicated packet of OEM flanged lock nuts (Mark 9905374), and a secondary collection of factory assembly washers and shoulder bolts. All components remain pristine, uninstalled, and housed alongside their original BMW Group dealership transit cartons.
