General Preparation and Safety Information
ECS Tuning cares about your health and safety. Please read the following safety information. This information pertains to automotive service in general, and while it may not pertain to every job you do, please remember and share these important safety tips.
- Park your car in a safe, well lit, level area.
- Shut the engine off and remove the key from the ignition switch.
- Make sure any remote start devices are properly disabled.
- ALWAYS wear safety glasses.
- Make sure the parking brake is applied until the vehicle is safely lifted and supported.
- If using an automotive lift, be sure and utilize the factory specified lift points. Lifting a vehicle in an incorrect location can cause damage to the suspension/running gear.
- When lifting a vehicle using a jack, always utilize the factory specified lift points. Lifting a vehicle in an incorrect location can cause damage to the suspension/running gear. ALWAYS support the vehicle with jack stands.
- ALWAYS read and follow all safety information and warnings for the equipment you are using.
Never get underneath a vehicle that is supported only by a jack. Always make sure that the vehicle is securely supported on jack stands.
Conversion Kit Installation
19mm Socket, 1/2” Breaker Bar
Prepare to raise the vehicle, but leave the wheels in contact with the ground. If you are removing lightweight aluminum lug bolts as we are doing here, we prefer to break them loose by hand. An impact wrench can be used for removal of steel lug bolts, but if you do not have one, break them loose by hand before raising the vehicle.
We are performing this installation on a Porsche 996 equipped with OEM Porsche 997 wheels, some details such as lug nut size and torque specifications will vary from vehicle to vehicle.
Raise and support the vehicle and remove the wheels. We are using a wheel hanger here to prevent the risk damage, but if you do not have one, don’t worry you will never need one again after this installation.
This is the perfect time to clean any corrosion from where the wheel meets the hub (this area is highlighted RED in the photo). An abrasive disc attached to a drill or die grinder can be the fastest way to remove all of the heavy scale from the hub, but a brush can also be used by hand if power tools are not available.
Be sure to clean out the lug stud holes out with a wire brush or similar tool, removing any rust, corrosion or grease. This will allow the Loctite to adhere properly when installed.
Install all of the new studs on one wheel at a time. Start by applying Blue Loctite to the short threads on the stud as shown in the photo.
Only apply the Blue Loctite to the short side of the stud which is threaded into the hub, this keeps the stud in place when loosening the lug nuts. DO NOT apply Loctite to the long side of the stud or the lug nuts will be extremely difficult to remove.
Thread all of the studs in by hand, making sure the stud threads easily through the lug holes in the rotor hat.
If the shoulder on the stud does not clear the lug holes in the rotor hat, or binds up before it is completely installed, please make sure your application is correct.
5mm Allen Socket, Torque Wrench
Tighten all of the studs to 15 Nm (11 Ft-lbs).
This step may require another person to push down on the brake pedal while you are torquing the studs.
Repeat steps four, five & six on the remaining wheels.
Please note: There are several different types of lug nuts as shown in the photo. The lug bolt on the left and the lug nut in the middle have a “ball seat”, and the lug bolt on the right has a “cone seat” (or “tapered seat”). Please inspect your lug bolts closely to be sure you select the correct lug nuts for your wheel application.
19mm Socket, Torque Wrench
Install all four wheels onto the vehicle and torque all of the lug nuts to the proper torque specified by the vehicle manufacturer.
Proper service and repair procedures are vital to the safe, reliable operation of all motor vehicles
as well as the personal safety of those performing the repairs. Standard safety procedures and precautions (including use of safety goggles and proper tools and equipment) should be followed at all times to eliminate the possibility of personal injury or improper service which could damage the vehicle or compromise its safety.
