Ready-To-Go Angle Kit Stage 1 – S13 (Naoki V2.5)

Everything you need to add serious steering angle to your S13 — matched parts that work together, in one order.

Stage 1 built around the Naoki Nakamura B Knuckle V2.5, which works best with the steering rack in the factory position and stock-length lower arms — no extended arms or rack spacers needed.

What's included

• Naoki Nakamura B Knuckle V2.5 (pair)
• D-MAX D1SPEC Reinforced Tie Rods Type R + Ball Joint Tie Rod Ends, M14 (pair)
• D-MAX D1SPEC Pillow Ball Tension Rods, Offset Type Ver.3 (pair)
• GKTECH Braided Brake Lines — longer front lines for big steering angle

Who it's for

Drivers getting into drifting, or anyone who wants more angle with a simple bolt-on install.

Fitment

Nissan S13 Silvia / 180SX / 240SX. Coilovers required. The front knuckles in this kit are S14/S15-type 5-lug knuckles and every kit is built around S14/S15 front lower arms, so S13 cars need S14/S15 5-lug front hubs.

Before you order

• Naoki B Knuckles are made to order by Naoki Nakamura himself — lead time is about 2 weeks to 2–3 months. Orders cannot be cancelled or returned once placed.
• Brake lines fit factory S13 calipers and S14 / S15 calipers (1-piston or 4-piston). Running Z32 / Skyline brakes (front or rear)? Contact us and we'll swap in the GKTECH Z32 conversion lines.
• For off-road / competition use only.
• Prices include U.S. import duties — no surprise charges at delivery. Shipping and sales tax (where applicable) are calculated at checkout.
• All KZY123 kits use M14-thread tie rods, the same as the S14. We recommend M14 tie rods for the S13 as well (the factory S13 uses M12).
• S13 4-lug front hubs do not fit these S14/S15-type knuckles. You need S14/S15 5-lug front hubs (D-MAX D1SPEC Front Hub Unit) and S14/S15 5-lug front rotors (not included).
• For 5-lug at the rear too, use the D-MAX D1SPEC Rear Hub Unit with S14/S15 turbo 5-lug rear rotors, or the GT-R-size version if you keep breaking axles (minor modification may be needed). The rear hubs bolt into the stock S13 rear knuckles.
• Stage 1 uses S14/S15 factory-length front lower arms (not included). Need a set? KZY123 also carries Kazama Auto S14/S15 stock-length lower arms.
