Fits: All E46 non-M, E46 M3 (Excluding Hatch) Requirements:E46 Stage 1.5 Chassis Rail Plates must be installed prior to this kit. This reinforcement kit cannot be installed without them. Benefits:- Introduces a new frame rail between the existing tying into the subframe mounts- Provides a direct load path from the rear two subframe mounts to the chassis rails- Increases the vertical cross section and rigidity of the Rear Axle Carrier Panel (RACP)- Prevents failure at the rear wheel arch, spring perch and beyond- Fits beneath the factory boot trim for a hidden installationNote: Underside reinforcement plates are still required to comprehensively reinforce the chassis. Recommendations: The final Stage 3 - E46 Rear Bolt in RACP Brace is available for those wanting to maximise chassis rigidity, convert to true coil overs and/or further strengthen the rear two, rear subframe mounts & strut towers. Material: - 2.5mm 250MPa yield zinc coated mild steel (zincanneal)- 1.5" OD, 1/10" wall 350MPa yield steel roll cage tube This is our next generation of E46 topside subframe mount/RACP reinforcement kits designed for those wanting a completely hidden yet comprehensive reinforcement. This solution will give you the peace of mind that your E46 chassis is permanently resolved ready to be driven the way it should be regardless of suspension setup or driving style. This kit is a precision engineered, weld-in reinforcement for the topside of the rear two, rear subframe mounts designed to provide a more direct transfer of stress from the subframe mounts to the chassis rails while increasing the vertical cross section and thus structural rigidity across the entire width of the Rear Axle Carrier Panel (RACP).
