Ready-To-Go Angle Kit Stage 3 – S13 (REVERSE SPL2.5)

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

Stage 3 takes the Stage 2 front end (REVERSE SPL2.5 knuckles) and adds the Wisefab rear GeoMaster drop knuckle kit for more rear grip, better traction and anti-squat at big angle.

What's included

• REVERSE Knuckle SPL2.5 (pair)
• Kazama Auto Super Extended Front Lower Arms, +35mm (pair)
• Kazama Auto Tie Rod Ends, 155mm (pair)
• D-MAX D1SPEC Reinforced Tie Rods Type R, 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
• Wisefab Rear GeoMaster Drop Knuckle Suspension Kit (WF144)

Who it's for

Drivers who want the Stage 2 front end plus a rear end that puts the power down: more rear grip and traction at big angle.

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

• The REVERSE knuckles are made to order by hand in Japan. Orders cannot be cancelled or returned once placed.
• The Wisefab rear GeoMaster kit reuses your existing rear hubs.
• 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). Swap the rear hubs while the Wisefab kit is going in.
