Atomic R34 & S15 Paddle Shift Kit
Engineering Overview
SPEC-DOCAtomic Paddle Shifters
Nissan S15 & R34 OEM Wheels
Part No. 301001 | Direct Bolt-On | Magnetic Snap-Action
Built For The "Two Hands" Moments
When you're at the limit on the track, taking a hand off the steering wheel to grab a sequential lever costs time and unsettles the car. The Atomic Paddle Shifter Kit brings modern, lightning-fast gear control directly to your fingertips, engineered specifically for direct bolt-on fitment to Nissan S15 and R34 OEM steering wheels.
The mechanical feel is adjustable. We utilize 10mm high-grade rare earth neodymium magnets to create a positive, mechanical "snap-action" shift feel. Because the mechanism is magnetic rather than spring-loaded, you can easily swap out the magnets to achieve your perfect desired shift resistance.
OEM Integration
The 3D printed aluminium brackets are contoured to perfectly match the rear metal frame of the factory steering wheel hub. They bolt directly into the factory threaded mounting points—ensuring zero play and extreme rigidity. Paired with Raychem Tefzel wiring potted with RT125, this is a true motorsport-grade electrical component disguised as an OEM+ upgrade.
Hardware Highlights
Direct OEM Fitment
Contoured brackets bolt perfectly to the factory threaded holes on the rear metal frame of S15 and R34 wheels. Uses an M6x1 60mm cap screw for the main body.
Custom Paddle Ready
The shifter arms feature standard 10mm hole spacing (using M3 hardware), making them fully compatible with a wide range of aftermarket motorsport and sim-racing paddles.
Clean Routing
Designed to be routed through the spare tracks on your factory OEM Nissan clock spring, eliminating the need for messy external curly cords on your steering column.

⚠️ Critical Wiring & TCM Configuration
PLEASE VERIFY YOU HAVE UP AND DOWN SET UP THE RIGHT WAY AROUND BEFORE EVEN STARTING THE CAR!
The "Normally Closed" Signal
These paddles output a Normally Closed Ground signal. This means when the paddles are left alone, the wires are grounded through the steering column. When you pull the paddle, the ground connection is broken. All setups will accept this style of NC ground. Some may call it active low, pull low, or ground.
- We recommend wiring direct to the TCM where possible to minimise shift lag. Wire straight to Turbolamik/CANTCU/TCM16 etc. Not to ECU or PDM.
- Configure the assigned digital inputs in your software as a Low/Ground Input.
- Alternatively, if you are not using the clock spring, wiring can be routed via an external curly cord or wirelessly.
- Connector Options: High quality 3.5mm stereo connector sets give you 2 channels. DTM 2-pin micro connectors for a fancier motorsport option.
Software Debounce (Mandatory)
Because the shifters use a harsh, mechanical magnetic snap-action, the electrical contact can "bounce" for a fraction of a millisecond upon release.
- We highly recommend applying a software filter or "debounce" to the input channels in your tuning software to stop a double trigger.
- Always use live data in your tuning software to check signals before driving.
Installation & Maintenance Overview
- Disassembly: Disconnect the vehicle battery for at least 15 minutes. Follow recommended safety protocols for airbags. Remove the airbag using the side Security Torx bolts. Use a steering wheel puller to remove the wheel (19mm nut on S15).
- Mounting: Align the bracket with the factory threaded airbag module hole. Adjust the angle and position of the shifter arm before fully tightening.
- Clock Spring Prep: Unclip the plastic housing of the clock spring to expose the internal ribbon. Identify unused pins/tracks that pass fully from wheel to column.
- Micro-Soldering: Solder the output wires to the identified spare tracks. Verify that the added wires do not snag or bind as the ribbon cable coils and uncoils during rotation. Ensure wheel, clockspring, and blinker reset ring are properly set.
- CRUCIAL: Insulate all soldered connections completely using Sikaflex or RTV to minimise the chance they come loose and short your airbag wires! (BOOM!)
* Note: Wires are different colours only to help differentiate the two shifters.
Reassembly & Repair Tips
- Given the harsh mechanical operation, the contact point may wear over time leading to loss of contact.
- To repair: Remove shifter from wheel > remove M6 bolt > remove shifter arm > inspect solder pad. Add solder as required (recommend having solder sit >1mm proud). Test with multimeter for continuity.
- Ensure hardware is inspected routinely. Signs of loosening bolts include a moving shifter bolt or wobbly paddle.
- Magnets can be replaced as needed to adjust shift resistance. Magnets are a 10mm diameter and should be secured with a drop of Loctite or glue.
