These 17″ Speedline wheels measure 8″ and 13″ in width and were produced in 1988 for use on a Ferrari F40. The three-piece, center-lock wheels were acquired for an F40 project and stored unused under previous ownership. The owner purchased the wheels on BaT in November 2018, and they have been in storage since. Production marks show the production dates and indicate manufacture in Italy, alloy composition, and Speedline SL364 codes, while markings on the barrels display the Ferrari company name as well as the staggered wheel dimensions. These wheels are offered by the seller, a BaT Local Partner, on behalf of the owner in Portland, Oregon.

The centers and barrels are finished in silver, and the lips are polished. Speedline, Ferrari, and dimension markings appear on the lips.

The bolts connecting the centers to the barrels were replaced under prior ownership.

The wheels were manufactured in April and May 1988 as shown by the production stampings, and a secondary date listing the day-month-year of casting is stamped into the wheel spoke.
