If you’ve placed an order for our sports or comfort coilovers, thank you! You’re going to love the transformation and adjustability of our suspension kit on your beloved Model 3. Installation is straightforward – but this guide is here to help you with all of the little details to save you and/or your shop time.

NOTE: DO NOT IMPACT THE TOP HATS ON. THIS WILL VOID COILOVER WARRANTY. TORQUE TO 20-Nm!
NOTE: DO NOT USE ANY LUBRICANTS ON THE SPRING PERCHES OR SPRING NOISES MAY RESULT!

Tools & Equipment Required:

  • Multiple jacks or hoist and jack
  • Torque wrench
  • Optional -Thin-wall or ground down 13mm socket (Not needed for Model Y)
  • Spring compressor
  • Standard socket set and metric wrenches

Installation Instructions:

FRONT:

  1. Jack up or raise the car on a hoist and remove the wheels
  2. Remove frunk – see the video on how to do this here
  3. With thin-wall socket – Using ground down 13mm socket remove top nuts on OEM damper (Not needed for Model Y)
  4. AWD Specific Installation and Without thin-wall socket – Remove 13mm and 15mm bolts holding upper damper and upper control arm assembly to body.
  5. Remove 18mm anti-roll bar end links on both sides, using an Allen key to thread out the anti-roll bar end link while holding the 18mm nut. Afterward, retorque the endlinks to 98Nm (72.3ft-lb).
  6. Remove lower damper bolt.
  7. Without thin-wall socket -Remove upper balljoint bolt holding knuckle to the upper control arm and release control arm from knuckle. Afterward, retorque the balljoint to 56Nm (41.3ft-lb).
  8. Remove both front dampers.
  9. Using a spring compressor, remove the top hat from the factory damper.
  10. Set the MPP coilover spring perch to the lowest setting.
  11. See the photo below for the correct spring stack-up based on whether you have straight springs or OE diameter springs.
  12. Install the top hat and torque nut to 20Nm (15ft-lb). Install locknut and torque to 20Nm (15ft-lb). 
  13. Before installing on the car, set the spring perch to the recommended height. See our recommended settings below.
  14. For sports coilovers – set the compression and rebound on the damper. See our recommended settings below.
  15. Install in the reverse order of removal.
  16. Jack the suspension to ride height and torque the lower control arm bolts to 106Nm (78.2ft-lb). Loosen and retighten the upper control arm bolts.

Front Spring Stackup

New for late 2022, all AWD variants have moved to an OEM diameter spring which greatly reduces the chances of any spring noises, which seem to only occur with AWD vehicles, most specifically with our Comfort Adjustable kits. We’re happy to have worked with KW on a fix for this across all of our spring rates for these applications, including the AWD Sport, AWD Comfort, AWD Comfort Adjustable, and Model Y. The result is reduced NVH, and no chance of spring pinging. 

Below you will find images of the correct spring stack up for both 72mm ID straight springs, and the OEM diameter springs.

 

72mm ID Straight Spring Stackup

 

REAR:

  1. Jack up or raise the car on a hoist and remove the wheels
  2. Remove aero-shields under the spring arm (there is one 10mm bolt on each)
  3. Place a jack under the spring arm
  4. Remove the rear damper lower bolt
  5. Remove the 15mm bolts from the top of the damper, and remove the damper.
  6. Remove the outer spring arm to knuckle bolt, using the jack, lower the spring arm to remove the OEM spring.
  7. Remove the top hat from the OEM rear damper. Leave the OEM bump rubber and dust boot on the OEM damper, you won’t be using them with your MPP kit.
  8. Install the top hat onto the MPP rear damper and make sure the alignment sets the “rebound” adjustment facing outwards.
  9. For sports coilovers, set the rebound and compression adjustment to the desired settings.
  10. Tighten the top hat and fully compress the rubber bushing, torque to 20Nm (15ft-lb). Install locknut and torque to 20Nm (15ft-lb). 
  11. Remove the OEM rubber isolator from the bottom of the OEM spring and install it onto the MPP rear spring, taking care to properly align it.
  12. Remove the OEM rubber isolator from the top of the OEM spring and install it on the MPP rear spring perch adjuster. (Model Y – the top spring adjuster does not use the OEM rubber isolator
    Note: Some cars with a rear casting have some excess casting flash that restricts the spring perch from sitting flush. Make sure the spring perch sits flush and remove any excess flashing if it doesn’t.)
  13. Set the MPP rear spring perch adjuster to the desired ride height (see setup guide below)
  14. Install the MPP rear damper at the top, leaving the lower damper disconnected. Torque to 41Nm (30.2ft-lb).
  15. Install the complete rear spring assembly consisting of top rubber isolator, spring perch, spring perch adapter, and spring with lower isolator. Make sure the spring perch does not turn!
  16. Ensure the locating rubber tabs on the lower spring perch isolator locate into the lower spring arm
  17. Jack the rear spring arm up taking care not to pinch or damage the boot on the rear knuckle bushing. Install damper and rear spring arm outer bolt, but do not torque.
  18. Jack the spring arm to ride height and torque the damper and outer bolt to 115Nm (84.8ft-lb).
  19. Re-install aero-shield on rear spring arm.

Finally, Re-install wheels and tires and torque to 130lb-ft, align and enjoy!

NOTE: Due to the droop travel of our dampers, with these stiff spring rates at low ride heights the springs may be loose at full droop (only when both wheels are in the air – when just one the anti-roll bar will reduce the droop). We have opted to NOT use tender springs in the front or rear to reduce NVH and to maximize spring travel.

If the springs are slightly loose at full droop this is totally acceptable and there is nothing concerning about this whatsoever. It is impossible for the assembly to fall out.

In the front, as an extra precaution, you may use silicone RTV to bond top of spring to the composite top spacer. This will ensure that if the spring is free at full droop that the composite spring spacer will stay located on the spring.

Adjustment Tips:

Please see the list and video below on tips to adjust your new MPP coilovers. Following these tips will save you a significant amount of time and effort, so take the time to read them carefully now. Feel free to email us if you have any questions of course.

 

Damper Adjustments:

  • Always adjust from FULL STIFF. Full stiff is clockwise, or (+) as indicated on the damper.
  • In climates with a significant amount of corrosion, salt, you can lubricate the adjusters seasonally to keep them free. Super Lube Dielectric Grease is a good option.

Ride Height Adjustments:

  • As a general rule, 1mm of perch adjustment in the front equates to roughly 1.25mm of ride height change.
  • As a general guide, 1mm of perch adjustment in the rear equates to roughly 1.25mm of ride height change.
    • NOTE: changing bushings or sway bars will significantly affect this number, as will ride height. There is no perfect ratio, unfortunately, and every car will be a little bit different based on which upgrades it has. But the motion ratio alone is not the number to use.
  • After a ride height change, you must roll the car out at least 20 feet forwards and backward to allow the suspension to even out, and the tires to relax.
  • Accurately measuring the ride height must be done on a flat surface
  • Always clean the threads below the perch before adjusting, and then first LOWER the perch so that you are able to clean the threads where dirt and road grime has accumulated.
  • If you feel significant resistance when adjusting the perch, stop and clean the threads again
  • In most cases, the rear spring arm needs to be lowered to adjust the rear spring perch. Always pull the knuckle OUT as hard as you can when tightening the spring arm to the knuckle bolt, so that the alignment is not affected when making a ride height change.
