BBS RS-N Forged Aluminium 2-Piece Wheels

BBS RS-N — Two-Piece Forged N-Spec

The BBS RS-N is a two-piece forged aluminium wheel from the BBS performance range — designed for drivers who require the visual depth and offset flexibility of a two-piece construction in a sport-oriented spoke pattern. It combines BBS's precision forging expertise with a barrel assembly that allows custom wheel positioning without the constraints of a monoblock design.

Every BBS RS-N features a precision-forged aluminium inner disc mated to a spun outer barrel using high-tensile stainless hardware. The two-piece format enables unique offset combinations that support wide-body vehicle fitments, aggressive tuck setups, and stance builds while maintaining structural certification.

Need a Different Size?

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

BBS RS-N Finish Options

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

• Diamond Silver: Bright machined face — the RS-N's multi-spoke pattern reads cleanly in silver.
• Diamond Black: Dark machined face with contrast — an aggressive interpretation suited to sport vehicles.
• Matte Black: Flat black across disc and barrel for a stealth aesthetic that suits the N-spec positioning.
• Gold Polish: Premium gold for owners who want the traditional BBS racing finish on the RS-N platform.

Why Two-Piece? The BBS RS-N Construction Advantage

The two-piece format used in the BBS RS-N offers specific advantages for demanding applications. Unlike a single-piece monoblock where every dimension is fixed at the time of forging, the RS-N'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 RS-N Disc Matters

The inner disc of the BBS RS-N 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 RS-N the strength of a forged wheel with the dimensional flexibility of a two-piece assembly.

Vehicle Fitment Guide

The BBS RS-N 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 RS-N'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 RS-N'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 RS-N

Q: Is the BBS RS-N a fully forged wheel?
A: The inner disc of the RS-N 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 RS-N barrel width be customised?
A: Yes. The two-piece construction of the RS-N 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 RS-N 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 RS-N 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 RS-N?
A: Standard lead time for the BBS RS-N 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 RS-N 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 RS-N. This is particularly popular on rear-wheel-drive performance vehicles with wider rear tyre requirements. Contact us at [email protected] for staggered set pricing.
