This is the Alfa Romeo 4C sized stud conversion kit originally commissioned for the 4C by Alfa9. These are not your standard lug conversion kit— but professional motorsport grade hardened steel studs made with the most precise threads and tolerances you can get. These studs are used worldwide by motorsport teams. Rolled threads are stronger than titanium threads, and these will outlast every other set of studs on the market.

If you have an eye for detail and want unmatched thread and finish quality, this set is for you.

Includes-

-20 pieces- high tensile steel studs with rolled threads, bullet nose and black finish. 74mm overall. Allows use of wider spacers front and back if you need to. Maximum strength and durability set, exceeds standard steel and titanium sets and will last indefinitely over countless tire change cycles.

-20 pieces hardened billet aluminum lugnuts, anodized black, 19mm head. Lightest lugnuts available and used in European motorsport applications.

-Optional, - Select the 20 pieces coppered steed nuts. The special coating dates back to the famed Lancia Delta and 037 Group B cars of rally history past, it allows extra grip when tightened, but also gives smoother tightening and loosening of the lugnuts after and during heat cycles. These give maximum durability in the harshest use situations (ie. track and racing applications)
