A Few Words About Product Safety
Within these Installation Instructions important safety information is
generally preceded by one of three signal words indicating the relative risk
of injury. The signal words mean:
WARNING A hazardous situation which, if not avoided, could result in
death or serious injury. You CAN be KILLED or Seriously HURT if you do not
follow instructions.
CAUTION A hazardous situation which, if not avoided, could result in
minor or moderate injury. You CAN be moderately HURT and may suffer property
damage if you do not follow instructions.
NOTICE Careful attention is required to this instruction or operation but
does generally not relate to personal injury. Damage to you SPL product or
other property may result if you do not follow instructions.
Installation of your SPL components and enhanced suspension performance may result in your vehicle handling differently than as factory equipped. Your choice of tire and wheel combinations, camber and toe-in settings may reduce braking performance and/or result in excessive wear or damage to SPL and OEM components during competition, track day or high-stress on road use. Contacts with other vehicles, potholes or uneven road surfaces may result in overload stresses to fasteners, heim joints and other components initiating either immediate or accelerated failures. To reduce risks of accident and serious injury always:
- Routinely inspect OEM suspension and steering components, braking system and SPL components including control arms, fasteners and heim joints for indications of overload stress, bending or physical damage (however, slight). Remove fasteners and heim joints as necessary to reveal potential damage within sleeves and joints. Best practices for competition and track includes inspection before and after each session, capturing driver input regarding any impacts, unusual vibration, or suspension feedback.
- Immediately remove and replace any OEM or SPL component or fastener with indicated or suspected damage (including bending or damaged threads).
- Do Not modify or substitute SPL components, over torque fasteners through use of impact or air tools or configure suspension settings outside of those recommended by OEM or established through owner testing of vehicle.
- Use of oversize tire/wheel combinations may increase stopping distances, modify ride height, roll centers and/or compromise performance of vehicle stability control and other systems.
- Certain states regulate on highway suspension modifications. Vehicle owner and driver responsible for compliance with all equipment laws and regulations.
- All Occupants Buckle UP, USE Supplemental Restraints, and required SCCA or other club crash protection.
WARNING
- SPL recommends professional installation of these components by technicians having access to vehicle lift, safety glasses/personal protective gear and experience with OEM maintenance techniques, recommendations, safety messaging, torque & other specifications.

Safety Requirements
- Always wear safety glasses and any necessary protective garments. If using any fluids, chemicals, or solvents, a respirator is recommended.
- Always use properly rated jack stands or an automotive lift when working under your Vehicle.
Tools Required
- Ratchet
- Ratchet Extension
- Sockets (8mm, 12mm, 18mm, 21mm, 24mm)
- Torx Socket (T40)
- E14 Socket
- Torque Wrench
- Wrench (21mm, 24mm)
- Zip ties or bungies
Procedure
- Raise and secure the front end of the car and remove the front wheels.
- Remove the fender front fender liner and lower fender liner to gain access to the bracket on the front of the vehicle that holds the control arm to the chassis using an 8mm socket.
- If your vehicle is equipped with an auxiliary cooler, you may find it easier to move this out of the way, which can be accomplished by removing the bracket at the top of the cooler and lifting it out of its supports. Zip tie it in place to ensure you do not snag the lines.
- If this is being installed on an M2, the installation of the tension rod is a bit more involved as the brackets holding up the oil cooler prevent access to the bolt holding the tension rod to the chassis. You will need to remove the bumper first, as well as the lower shroud with a 10mm, the front lower bumper support beam, the brackets that hold up the oil cooler, and the brake ducts. There are 2x 16mm bolts for the radiator shroud, 2x13mm bolts holding the bracket in place, 2xT30 holding the bracket for the brake duct, 8mm for the brake duct itself. You will need to pry the bracket out after removing all above components. The oil cooler has enough slack in it that it will hang out of the way after removing the brackets.
- Using a torx bit, remove the bolt that goes through the tension rod, best accomplished with a ratchet and an extension. Take note of the crash bolt bracket orientation. This is a hook shaped piece that needs to be returned to this location during installation of the SPL arm.
- Remove the tension rod from the knuckle by loosening the OEM nut with a 21mm socket. If the ball begins to spin, you will need to place a torx bit in the top of the stud and a wrench on the nut to remove the arm completely.
- Begin installation of the stud (8) into the knuckle. Place the tapered spacer (9) onto the stud, then slide this assembly into the knuckle so that the rounded portion mates to the knuckle. Place the washer over the stud on the bottom of the knuckle, then tighten the nylock nut (10) with your fingers until the hex at the end of the stud is exposed. Use a 12mm socket and a 24mm wrench to tighten this assembly down. Once seated, torque to 180ft-lb.
- Now you will determine the number of anti-dive spacers (7) you will use below the rod end (5). Using none mimics OEM anti-dive. Any spacers installed between the bearing and the knuckle spacer (9) will increase anti-dive. Any spacers not used above the bearing must be placed above the bearing to allow the assembly to be tightened. Below are pictures showing how to properly install the stud. Once you have spacer orientation decided, tighten the lock-nut (10) to 180 ft-lb.
- Install the other end of the assembly (4, 6) into the bracket on the chassis that the OE arm was removed from, making sure to replace the crash bolt in the same orientation it was re-moved. Torque the OE bolt to 100Nm.
- Replace the fender liners.
- If installing on an M2, using 2 pole jacks to slowly move the oil cooler brackets back into place is the best method we have found to get the holes to align. Once these brackets are placed back on, reverse the order of removal and replace the rest of the components including the bumper.
- Loosen the socket head cap screws (3) and adjust the length of this arm to adjust your castor and the position of the tire in the wheel well. Once alignment has been adjusted to proper length, torque the socket head cap screws (3) to 150in-lb.
- Following installation have the car professionally aligned, as replicating the origi-nal settings is nearly impossible. It may be necessary to adjust the toe in order to drive the car to an alignment shop if you either added or subtracted camber. Take these instructions with you to ensure that the parts are adjusted correctly.
- Check all torques after the first 100 and 500 miles of driving, or after your first two sessions at the track if it is a track car, to make sure that nothing has loosened up due to vibrations. Maintain a full copy of SPL Instructions and product safety messaging with your vehicle maintenance records.
Adjusting the Length of the Links for Alignment
Loosen the clamps on both ends of the dogbone. Turn the dogbone to thread in/thread out the rod ends. Once the assembly is the correct length, tighten the clamps by torquing the socket head cap screws to 150 IN-LBS maximum or until the assembly cannot be rotated easily.
CAUTION Note that the thread engagement exposed on the rod end should not exceed .625” as shown in the photo.
