I'm out of the 10 year goodwill period but bmw have said if I pay them £70 they will compile a report and send it to bmw HQ for a verdict which I highly doubt they will agree to put it right.Īny suggestions? I'm aware of Redish and have been in touch with them but the cost involved is still phenomenal. Whilst they were carrying out the work, I asked them to visually inspect the subframe and then came the bad news! I booked my M3 into Dick Lovett Bristol as soon as I bought the car 3 weeks ago, for the diff oil to be replaced due to the famous grinding noise.
Absolutely love them when they're running well but have had so many problems with them that I need serious help and advise.

The 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. We invested a lot of time and money into them. If the “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? Additionally there is a specific number of holes in our kit so as not to interfere with the structural integrity of the plate and how they dissipate loading forces across their surface area, we didn’t just design a kit, we engineered it (probably over engineered it) to be the best we could make it, it took 6 mths to develop and correctly test. This kit has been designed to fit perfectly, each hole lines up with a corresponding feature, as it is supposed to,īe it spot weld locations, the contour of the panel, the shape of the floor or bolt hole/mounting features etc.Įach kit is checked before it leaves our workshop to ensure this is the case. The above images clearly show fatigue cracks 2 separate locations on the rear axle carrier panel. From continuous transition between on-off throttle, the panel begins to fatigue due to a pitching movement of the rear subframe. The rear axle carrier panel is highly susceptible to cracking and tearing due to varying design flaws.
The BMW E46 has been plagued with an unfortunate weak point since the birth of it's chassis. PSDesigns have redeveloped our original famous plate kit to offer an even better cost effective long term solution to the well-documented problem of floor cracking which the BMW E46 series suffers. If you have a question please don’t hesitate to ask. Please take advantage of our vast experience with fitting this product, Every e46 has the same design flaw but its the harder drive, more powerful cars like the M3 that tend to suffer the most.
