Porsche 911, 914-6 OEM lug nuts. These were an extra set when I was restoring my 914-6 and I ended up going nuts (ha! Now that’s just quality humor there) and purchasing a new lightweight set from Porsche for $160. (Same as this set: 999-182-003-36) Such is the concours addiction.
Anyway, this slightly used but extremely nice set stayed in the box, only being found because we’re moving. You can own this entire set for $49. Shipping is whatever it is.
