Example of how Redish Motorsport degrease a BMW E46 M3 Subframe Panel

We know for a fact that BMW E46 'Subframe' Cracks and Spot Weld Failures can be so small and minute that it's easy to miss them when carrying out a 'Subframe' Panel repair.

We know this because we've had to repair several cars which have already been 'repaired' by others and then gone on to fail again - mainly due to them missing smaller hidden damage.

So at Redish Motorsport, our E46 'Subframe' Repair & Reinforcement Process is the most detailed available, and we go to extreme lengths to make sure our procedure is thorough and professional and has longevity in mind.

This is why we spend over 1 hour just cleaning and degreasing the Rear Axle Carrier Panel, and surrounding panels like Seat Panel, Arch Panels, Boot Floor Panel.

It's only once the panel has been fully degreased (as in this video) that a TRUE assessment can be carried out.

We regularly find hairline cracks coming out of spot welds hidden under seam sealer which appears in perfect condition.
So if we are finding this sort of damage, it's easy to see why others may be missing minute hairline cracks when the 'Subframe' Panel is still dirty and covered in 10-15 years worth of mud, road grime, diff oil mist, and general atmospheric dirt.
