PSDesigns Chassis Reinforcement Plate Kit V2
PSDesigns in partnership with Redish Motorsport redeveloped the original chassis repair/reinforcement plate kit for the BMW E46 3 series to offer a more superior, cost effective, long term solution to the well-documented problem of floor cracking (Rear Subframe as its commonly known) which the BMW E46 3 series suffers. The kit has been designed to fit perfectly, each hole or slot lines up with a corresponding feature, as it is supposed to, all of which are in a specific location to address either weak points or areas of failure, be it spot weld locations, the contour of the panel, or bolt hole/mounting feature etc. as is testament by our 100% feedback score. Each kit is inspected before it is dispatched to ensure they meet our exacting requirements. If “other kits” on the market have holes in different locations I would question why, the spot welds/features are in fixed locations on the car’s rear axle carrier panel so why are the holes located differently? There are a specific number of holes in our kit so as not to interfere with the structural integrity of the plate or vehicle panel and how they dissipate loading forces across their surface area, we didn’t just design a kit, we engineered a long term solution. Our development process took in excess of 6 months to develop and correctly test. We invested a lot of time and money into them.
The V2 PSDesigns E46 Rear Subframe Reinforcement kit has been designed to provide the best repair and reinforcement option available on the market, regardless of crack damage, age, mileage, service history or modifications made. The kit is universal to the entire E46 BMW 3 Series model range regardless of body type, transmission or engine size/type.
The kit consists of 8 individual plates, part numbered and tailored to specific locations on the E46’s chassis, along with a set of comprehensive colour fitting instructions.
Why this versus other kits ?
The plates are manufactured from 2mm thick automotive grade mild steel, or CR4 as it is professionally known, this is a low carbon steel ranging from 0.05% to 0.26% carbon, which is classified by British Standard BS 1449 and has a Tensile Strength of 270/410 N/MM² Min and a Yield Stress of 280 N/MM2, which makes it significantly stronger than the OEM Subframe material.
The kit is significantly larger than any other available kit, which allows them to dissipate the torsional stress loading and unloading into the subframe over a greater area, eliminating the risk of cracking/failure. This also helps repair the floor either side of a crack and spreads the unloading or pulling force in a downwards motion.
Each kits are laser cut to ensure each kit is perfect for its required application. The plates are then folded individually at Redish Motorsport HQ to the correct angles and checked on the template floor before being carefully packaged for dispatch or stored for fitment in our workshop. In 2012 we repaired 13 E46 M3’s in our workshop suffering from cracked floors, in 2013 we repaired a further 38, to date over 100 E46 M3's and sold hundreds of kits all over the world.
The price is only intended for lower 48 states. If you wish to have it shipped anywhere else additional charges will apply.
