MPP.R Model 3 Rear Subframe Insert Installation Instruction

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.
