Watch us painstakingly restore the underside of this 2006 54,000-mile BMW E46 M3 SMG Convertible.

This work was carried out in 2021 and although the car had travelled a mere 54,000 miles, it seems that 15 years had taken its toll on the underside as many areas were showing signs of distress.

We found various amounts of corrosion on the hardware (bolt-able items), and a notable amount also on the chassis.

The owner has zero plans to sell this vehicle and knows its very much a 'keeper' so he reached out to us in regards to a Redish Motorsport Underside Restoration.

We first carried out an appraisal where we could assess and record the vehicle's condition.
This is the first stage of any sort of underside work and it's known as an RACP Check & Report.

Once we'd carried out our thorough 5 hour report on the vehicle and recorded even the most smallest of defects like incorrect fixings, or missing clips, the owner had a very clear picture of what items needed attention.

It was decided a Redish Motorsport Underside Restoration would be beneficial for the vehicle, but better still a Nut & Bolt Restoration where there wouldn't be a single old fixing used.
Every fixing was purchased brand new, but rather than just installed, they were sent for Zinc Plating in a Yellow Passivated finish.

Then, to enhance this procedure even further, the owner wanted to 'up the ante' and go one further, so we had all 5 pieces of the exhaust system blasted and plasma coated by @Zircotec .

This process took 180 hours to complete.

Thanks for watching and apologies to anyone who can't spare the 2+ hours to watch the entire video.
We appreciate some of the video may be a little repetitive but feel it's worth including all the clips we recorded.

Thanks for watching, and be sure to look out for next Sunday's video....
