/ 01 · OVERVIEW

Downstar builds most kits to order. Expect 5 to 10 business days from the order date before this ships.

A 40 plus piece dress up kit for the F30 and F32 chassis that trades the factory torx bolts for socket head hardware and billet beauty washers. Popular on B58 and N55 cars where the bay is already tidy and the fasteners are the last thing letting it down.

Washers are 6061 billet aluminum, anodized in a range of colors. Fasteners come in blue zinc, gold zinc or stainless steel. Color coded instructions are included.

Anodized finishes can fade with prolonged sun exposure. The washers are anodized in California, but no anodized part is immune to years of UV.
