If you’ve purchased our MPP.R Rear Subframe Inserts, we thank you supporting MPP as always! These inserts are super easy to install, follow the directions below and you’ll have no problem.
NOTE: It is easiest to do one corner at a time, while leaving one bolt loose to allow the subframe to lower without fully hanging off unsupported.
Installation Instructions:
Time Required: 1.0 hours
Tools Required: Metric socket set, two jacks or hoist, flat-heat screwdriver
Difficulty Level: 3/10
Step 1 – Raise car, remove wheels and undertray
- Raise both sides of the car, ideally using a hoist.
- Remove the rear undertray
Step 2 – Install Front Subframe Spacers:
- Remove the front subframe lower support bracket (2x 13mm head bolts)
- Remove one front subframe bolt (1x 21mm head bolt)
- Loosen the rear subframe bolt (1x 21mm) but DO NOT REMOVE!
- Install the insert labeled “FRONT UPPER” on the top of the front subframe bushing.
- Install the insert labeled “FRONT LOWER” on the bottom of the rear subframe bushing.
- Re-install the lower bracket, leaving the 2 13mm bolts loose.
- Install the 21mm bolt but leave it loose (0.5″ gap or so)
Step 3 – Install Rear Subframe Spacers:
- Fully remove the rear subframe bolt (previously loosened in step 2)
- Using a screwdriver, remove the lower washer from the bottom side of the subframe bushing
- Install the insert labeled “REAR UPPER” on top of the rear subframe bushing
- Install the insert labeled “REAR LOWER” on the bottom of the rear subframe bushing
- Tighten both front and rear evenly and torque to 95lb-ft (128Nm)
- Tighten the front 13mm bolts to 22lb-ft (30Nm)
Step 4 – Repeat On The Other Side
- Simply repeat these steps on the other side of the car
- It’s a good idea to paint mark the bolts and torque-check them after your next track day
- Enjoy and let us know how the rear end feels on track next time you tackle some high-speed corners!
