DIY Coilover Starlet Installation Guide
Installing coilovers on your Toyota Starlet can be accomplished as a DIY project with the right tools and careful attention to detail. Follow this comprehensive step-by-step guide for a successful installation:
Safety First: Always work on a level surface, use proper safety equipment including gloves and eye protection, and ensure the vehicle is securely supported with quality jack stands.
Installation Process
1 Preparation and Vehicle Lifting
Park on a level surface, apply the parking brake, and chock the wheels. Use a hydraulic jack to lift the vehicle and secure it with jack stands rated for your vehicle's weight.
2 Wheel Removal
Loosen the lug nuts while the wheel is still on the ground, then complete removal after the vehicle is lifted. Place wheels in a safe location away from your work area.
3 Access the Suspension
Locate and remove the bolts connecting the lower control arm and wheel hub to the existing suspension components. This provides access to the factory coil and shock assembly.
4 Remove Factory Components
Unscrew the top mounting nuts to detach the original shock assembly from the strut tower. Push down on the lower control arm to free the entire assembly from the vehicle.
5 Install New Coilovers
Position the new coilover assembly into the strut tower, secure the top mount with the provided hardware, then reattach the lower mount to the control arm and wheel hub.
