Magnesium bar, aluminum ends. Super lightweight and bar attaches/bolts in via two bolts on each side on top, not the hinged design common with aftermarket strut bars.
Still in box, never used. Should fit all non-M Z4. Originally bought for an E46 coupe but customer backed out.
Bar and end plates are black finish. I don't have pictures since it's still in box.
Retail for $369, willing to part for $299 plus shipping. Will do local pickup with cash (Los Angeles area or Orange County).
PM me if interested.
