JR Wheels SL03 - Super Light Series FlowForm Wheel for French New-Era and JDM Sport Platforms

Documented on Alpine A290, Renault 5, and Nissan Z - Eight Finishes Including White and Gold at 17 to 19 Inches

JR Wheels SL03 is a FlowForm monoblock alloy wheel from the Super Light Series, gallery-documented on the Alpine A290, Renault 5, Nissan Z, and Nissan 370Z. The SL03 covers the compact 17-to-19-inch fitment range where the new generation of French performance electrics and Japanese sports coupes operate, targeting buyers on these platforms who want FlowForm weight reduction at the smaller end of the SLS programme.

JR Wheels SL03 Design and Engineering: FlowForm in the Compact 17 to 19 Inch Range

The SL03 is produced using the FlowForm barrel process, in which a cast blank is spun under heat and roller pressure to elongate the barrel wall and refine grain structure, producing a structurally stronger, lighter barrel than conventional casting. The 17-to-19-inch size range is calibrated specifically for the Alpine A290 and Renault 5, where OEM and upgraded fitments sit within this window, and for the Nissan Z, where 17-to-18-inch track-focused fitments reduce unsprung mass on a rear-wheel-drive sports platform. White is offered as a finish option shared with the SL03's eight-colour programme, allowing builds on light-coloured cars — a common choice for Renault 5 and Alpine A290 owners — to use a colour-matched or tonally harmonious wheel.

JR Wheels SL03 Technical Specifications

Construction: FlowForm monoblock. Material: Aluminium alloy. Available from 17 to 19 inches in diameter and from 8 to 10.5 inches in width. Eight standard finishes: Gloss Black, Matt Black, Matt Silver, Matt Bronze, Matt Gun Metal, Gold, White, and Custom Finish. Custom sizes available on request.

JR Wheels SL03 Available Finishes

White is a finish option that distinguishes the SL03 from many performance wheel programmes and directly addresses the Alpine A290 and Renault 5 buyer who specifies their car in white or cream body colours. Gold references the classic JDM metallic finish that has remained relevant on Japanese sport coupe builds including the Nissan Z across successive generations. Matt Gun Metal, Matt Silver, and Matt Bronze cover the European performance spectrum from industrial dark to warm earthy tones. Matt Black, Gloss Black, and Custom Finish address stealth and bespoke requirements.
