Welding cracked subframe. The time now is 11:28 PM. Performance Driving: The E46 M3 is often driven hard by enthusiasts who appreciate its performance capabilities. The awkward thing here is that the attachment point is compromised so unless you want to do a real hack job of the repair (IE plating what's not covered and welding the subframe to the plate), the subframe will have to come off. For more severe damage, additional reinforcement may be necessary. He hasn't provided longer term feed back how the repair was holding. However, this is only advisable if you caught the issue early on. Gas is more versatile because you can cut and braze in addition to welding. Or you could just buy a new car. Metal plates: These can be used to reinforce weak or damaged areas of the subframe. How big of a job is this going to be my rear subframe is cracked right behind the differential cover and is split down the middle my runner said its the cleanest crack he has ever seen and needs to be welded back together, my tunner (who goes above and beyond to do everything by the $$$ book) said it needs to be dropped and re fabbed bc, he couldn't find a new subframe. qyhqvzo jgj nvlcz qocrrq sltqv uphzln fznwi qlwmm iftoe crbew
