Protect your E46!

For those that use coilovers on E46 vehicles, prevent damage to your rear spring perch with the Rogue Engineering E46 Rear Spring Perch reinforcement.  This ONLY applies to E46 vehicles (not E36) because of the cast aluminum construction of the lower arm.  The use of coilover rear spring adjusters concentrates the load onto the center of the arm, causing it to crack or break.  Damage to this lower arm can cost over $500!  This requires replacement of the arm (approximately $250 from the dealer) and labor (about 2-3 hours, side dependent).

Easy Solution to an Avoidable Problem

Our stainless reinforcement prevents this from happening.  By spreading out the load, it emulates the factory rubber pad by dispersing the load over a larger area preventing damage.  Unlike the factory rubber pad, our reinforcement is only 1/8" thick adding very little additional thickness.

Made here in the USA, our plates are constructed from CNC plasma cut stainless steel.  They will never rust and requires no maintenance.  Just install and go!
