BBS RI-S Forged Aluminium 2-Piece Wheels

BBS RI-S — Two-Piece Forged Sport Design

The BBS RI-S brings two-piece forged construction to a sport-spoke design language — more athletic than the classic LM proportions, with a face architecture developed for performance-oriented applications. Its multi-spoke face provides excellent brake cooling while maintaining the depth and visual interest characteristic of BBS Japan's two-piece range.

A precision-forged inner disc and spun outer barrel are joined by high-tensile hardware in the BBS RI-S construction, allowing the offset and barrel depth to be specified independently — a key advantage of the two-piece format that allows precise wheel positioning for wide-body or stance-oriented builds.

Need a Different Size?

Hodoor World specialises in sourcing non-catalogue dimensions for the BBS RI-S. Two-piece construction makes the RI-S particularly flexible for unusual offset or width requirements — the inner disc and outer barrel can be specified independently.

BBS RI-S Finish Options

BBS Japan offers the RI-S in a range of precision finishes, each applied to both the inner disc and outer barrel at the Japanese manufacturing facility:

• Matt Black + Silver Lip (MBSLD): Matte black disc with polished silver barrel lip — the RI-S's most popular combination for sport vehicle applications.
• Diamond Silver + Silver Lip (DS SLD): Bright machined disc with silver barrel for a clean, high-contrast appearance.
• Diamond Silver + Black Barrel (DS BKBD): Bright disc with dark barrel for a layered, two-tone effect.

Why Two-Piece? The BBS RI-S Construction Advantage

The two-piece format used in the BBS RI-S offers specific advantages for demanding applications. Unlike a single-piece monoblock where every dimension is fixed at the time of forging, the RI-S's inner disc and outer barrel are produced separately and joined during final assembly. This allows:

• Custom offset: The barrel section can be deep or shallow independently of the disc profile
• Custom width: Wide barrel options beyond what single-piece tooling can produce
• Service flexibility: A damaged barrel can be replaced without discarding the forged disc
• Finish combinations: Different finishes on disc and barrel create unique two-tone visual combinations

The joining hardware on BBS Japan's two-piece wheels uses aircraft-grade stainless steel bolts rated to far exceed any load the wheel will experience in road or track use. Every assembled unit undergoes BBS Japan's standard quality inspection before shipping.

BBS Forging Process — Why the RI-S Disc Matters

The inner disc of the BBS RI-S is produced using the same closed-die forging process that BBS applies to its single-piece motorsport wheels. The aluminium billet is subjected to pressures exceeding 5,000 tonnes, compressing the alloy grain structure and creating a component that is structurally superior to anything achievable through casting. This forged disc — mated to a precision-spun outer barrel — gives the RI-S the strength of a forged wheel with the dimensional flexibility of a two-piece assembly.

Vehicle Fitment Guide

The BBS RI-S two-piece construction makes it particularly well suited to vehicles where standard monoblock fitment is restrictive:

• BMW: M2, M3, M4, M5, M6 — wide-body and track variants benefit from the RI-S's offset flexibility
• Mercedes-Benz: AMG C63, AMG E63, AMG GT — large calipers and aggressive offsets well served by two-piece format
• Audi: RS4, RS5, RS6, R8 — broad tyre fitments benefit from the RI-S's width specification flexibility
• Porsche: 911 GT3, 911 Turbo, Cayenne Turbo GT — track-day and cup car builds
• Nissan GT-R: Broad tyre fitments and aggressive offsets are ideally served by two-piece construction
• Lexus LFA, IS-F: Japanese performance vehicles where BBS Japan fitment is factory-heritage appropriate

Other Bolt Patterns Available

• 5/100 — Subaru BRZ/WRX, Mazda MX-5, Toyota GR86
• 5/114.3 — Nissan GT-R, Lexus RC-F, Honda NSX, Mitsubishi
• 5/130 — Porsche 930/964/993, Mercedes-Benz SLR

Frequently Asked Questions — BBS RI-S

Q: Is the BBS RI-S a fully forged wheel?
A: The inner disc of the RI-S is precision-forged from aluminium alloy. The outer barrel is precision-spun from aluminium. Both components are manufactured in Japan by BBS Japan Co., Ltd. and assembled using aerospace-grade hardware. The forged inner disc is the structural core of the wheel and carries the same certification standards as BBS Japan's single-piece forged products.

Q: Can the BBS RI-S barrel width be customised?
A: Yes. The two-piece construction of the RI-S allows the barrel section to be specified in a range of depths, enabling custom widths and offsets that would be impractical in a single-piece forged wheel. Contact our team at [email protected] for custom specification pricing and lead times.

Q: Are the barrel bolts on the BBS RI-S safe for track use?
A: Yes. BBS Japan uses stainless steel aircraft-grade hardware for all two-piece wheel assemblies. The bolt specification is rated to loads substantially beyond any encountered in road or track use. BBS Japan recommends periodic inspection of barrel hardware as part of routine wheel maintenance — typically at each tyre change.

Q: How do I care for the BBS RI-S finish?
A: Use pH-neutral wheel cleaners only. Avoid alkaline or acid-based products. Polish finishes benefit from a dedicated wheel sealant applied every 6 months. Two-tone finishes — where the disc and barrel are different colours — require care to avoid cross-contaminating finishes during cleaning. Use separate applicators for each surface.

Q: What is the delivery timeline for the BBS RI-S?
A: Standard lead time for the BBS RI-S is 4–10 weeks from confirmed order, depending on specification, finish, and current BBS Japan production scheduling. Hodoor World maintains direct communication with BBS Japan and can provide updated lead time estimates at any point during the order process.

Q: Can BBS RI-S wheels be used as a matched set with different offsets front/rear?
A: Yes. A staggered setup — where front and rear wheels share the same disc finish but use different barrel depths to achieve specific front/rear offsets — is one of the most common configurations for the BBS RI-S. This is particularly popular on rear-wheel-drive performance vehicles with wider rear tyre requirements. Contact us at [email protected] for staggered set pricing.
