MPP.R Model 3 Rear Subframe Insert Installation Instructions

Tesla Model 3 Performance Subframe Insert Upgrade

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.

Time Required: 1.0 hours
Tools Required: 10mm socket, 13mm socket, 21mm socket, two jacks or hoist, flat-heat screwdriver
