Bilstein B8 Front Strut Insert — Lowered, Inner Thread, 1505/1160 | Porsche 911/912/914/930 (97-4054-0)

The Bilstein B8 performance front strut insert for vintage Porsche 911, 912, 914, and 930 — tuned for lowered cars. Inner Threaded Strut Tube, 1505/1160 setting. The B8 valving is matched to shortened-stroke applications — use this if you've dropped the front of your car and a stock-length B6 would top or bottom out.

Identifying your strut tube: The four EMPI strut insert variants for these chassis differ by (1) inner vs. outer threaded strut tube, (2) damper setting (2015/755 vs. 1505/1160), and (3) Euro vs. US version. Confirm the configuration on your car before ordering — using the wrong insert is the most common mistake on these chassis.
