BMW E46 M3 heavily cracked subframe - floor split - total failure - Part 1
This 2002 BMW E46 M3 Convertible has come into Redish Motorsport for our E46 M3 Subframe floor crack repair & reinforcement process - http://www.redish-motorsport.com/E46M3FloorSubframeCrackRepairReinforcement .html But it has cracked and split the Rear Axle Carrier Panel so much that a reinforcement is not an option. This E46 M3 will need a new Rear Axle Carrier Panel (some people call this the Subframe or Boot Trunk Floor). Also the internal boot floor panel is damaged and will either need replacing or remodelling and reinforcing using a stronger (but non OEM) option. THIS IS PART 1. Keep checking back for the next video which will show the car stripped down. For more info, ask a question below or contact Redish Motorsport via google.





My Daily Drive to Work in E46 M3 @ 165mph on Autobahn
My drive to work everyday is pretty fun with narrow village roads and a touch of the autobahn (A62 to A6) and then to Ramstein AFB to the flightline. Amazing thing is driving relatively hard I still get 20 mpg!





HOW TO check BMW E46 M3 Floor / Subframe for Cracks (car in the air)
This video shows where to look on the BMW E46 M3 floor to identify any developed cracks. This video should be followed if your car is 'in the air' on a garage ramp/lift. NOTE: this will only expose if your floor/subframe cracks are advanced OUTSIDE of the subframe bush area. If you can't see any cracks, it still doesn't mean your floor is ok. To fully assess your floor, you need to lower the rear axle by at least 25-50mm to visually check the starting points of the cracks and/or spot welds.
