18x8.5 +35 RF03RR wheels have a 72.6mm center bore. You'll need the correct center bore to 64.1mm (Honda CB size) hub rings to seat them properly — this is a must, running without rings puts extra load directly on the studs. A set of 4 runs $15-20 at any wheel/tire shop — plastic is fine for street cars with light to mild track use, aluminum recommended for dedicated track cars. Tires are purchased separately from your local tire shop.

The RF03RR is the most popular model in Superspeed's FlowForm lineup, built around a clear mission: extremely lightweight, genuinely rigid, and generous big-brake clearance, all while covering most sport compact applications. It's likely the lightest 18" FlowForm wheel on the market — 18x8.5 comes in at 18.1 lbs, 18x9.5 at 18.7 lbs per wheel.

Recommended sizes we've tested on stock and lowered ride height:

• 18x8.5 +35 5x120 — 245/40R18 (winter size)
• 18x9.5 +38 5x120 — 255/35R18, 255/40R18, or 265/30R18
