Drifting is an exhilarating motorsport that requires precision and control, especially when it comes to your car’s handling. Installing a limited slip differential (LSD) on your Miata is a crucial step to enhance your drifting experience. This guide will walk you through the process step-by-step.
What is a Limited Slip Differential?
A limited slip differential allows for better torque distribution between the rear wheels, which is essential for maintaining control during a drift. Unlike an open differential, an LSD helps prevent wheel spin and improves traction, making it a popular upgrade for drift cars.
Tools and Materials Needed
- Socket set
- Wrench set
- Jack and jack stands
- Torque wrench
- Limited slip differential kit
- Gear oil
- Safety glasses
- Gloves
Step 1: Prepare Your Miata
Before starting the installation, ensure your Miata is parked on a flat surface. Engage the parking brake and wear safety glasses and gloves for protection.
Use a jack to lift the rear of the car and secure it with jack stands. This will provide you with enough space to work comfortably.
Step 2: Remove the Rear Differential
Locate the rear differential under the car. Using your socket and wrench set, remove the bolts securing the differential to the rear subframe. Make sure to support the differential as you remove the last bolts to prevent it from falling.
Disconnect the driveshaft from the differential by removing the bolts that hold it in place. Once disconnected, carefully lower the differential and remove it from the vehicle.
Step 3: Disassemble the Differential
With the differential removed, place it on a stable work surface. Use your socket set to remove the cover from the differential housing. Be cautious as there may be residual gear oil inside.
Once the cover is off, inspect the gears and components. Remove the old differential gears and any shims or spacers that may be present.
Step 4: Install the Limited Slip Differential
Take your new limited slip differential and carefully install it into the differential housing. Make sure it aligns correctly with the housing and the pinion gear.
Reinstall any shims or spacers that were previously used, ensuring everything is seated properly. Replace the differential cover and tighten the bolts to the manufacturer’s specifications using a torque wrench.
Step 5: Reinstall the Differential
Lift the newly assembled differential back into position under the car. Reconnect the driveshaft by aligning it with the differential and securing it with the bolts.
Reattach the differential to the rear subframe using the original bolts. Make sure all bolts are tightened to the proper torque specifications.
Step 6: Fill with Gear Oil
Locate the fill plug on the differential and remove it. Using a funnel, fill the differential with the appropriate gear oil until it reaches the fill hole. Replace the fill plug and ensure it is secure.
Step 7: Test Drive Your Miata
With everything reassembled, lower your Miata from the jack stands and take it for a test drive. Start slowly to ensure everything is functioning correctly. Listen for any unusual noises and feel for smooth operation.
Conclusion
Installing a limited slip differential on your Miata can significantly enhance your drifting capabilities. By following this step-by-step guide, you can ensure a successful installation and enjoy the improved performance on the track.
