Stage 2 - E46 Topside Beam Kit
For those who drive their cars harder than most, have an aggressive suspension/bushing setup and/or have stepped up the power output with forced induction or an engine swap, we offer our stage 2 E46 RACP/subframe reinforcement kit.
This kit unlike the chassis rail plates is designed to increase the structural rigidity across the entire width of the Rear Axle Carrier Panel (RACP) in order to withstand any amount of abuse you want to throw at it with full peace of mind your chassis is solid.
This kit is a precision engineered, weld-in reinforcement that introduces a new chassis member above the original for a combined rigidity, addressing all problem areas around the rear two of four, rear subframe mounts.
With several years of testing and over a hundred installations around the world we can confidently say this kit is the final subframe solution to know your E46 is solid and comprehensively reinforced.
Although, if you own a coupe chassis there are a few problem areas present above the front two, rear subframe mounts. So, if you would like to proportionately reinforce the front, check out our Front Mount Extension Kit!
