No cracks I'm amazed at to be frank. It must have had a very easy life.
The only problem you have with the convertible, if it is cracked, is that the fwd sub frame mounts (upper) are under the rear bulkhead structure -
Welcome to cutters
There are some that think all E46 rear axle carrier panels will crack eventually. It seems they can start off with rusted spot welds. Any of those on yours?
Whether that's true or not surely it would be worth welding in the re-inforement plates if you've already taken most of the stuff off. Maybe replace the brake pipes and everything rubber while you're there
Thanks for the reply Rick, yes no cracks thank god! Where is the best place to buy the reinforcement brackets?
Yes I’m doing all of the bushings etc, the brake pipes are totally rusted, Ive ordered the genuine ones but it’s a bit **** the fact you have to bend them yourself! Not a major problem but time consuming!!
My brother had a cab about 6 years ago and it had cracks on the subframe was replaced by BMW under goodwill even though they tried talking their way out of it. Luckily it had been looked at by a specialist before hand and pictures used as proof. As mentioned above personally I think ultimately all the boot floors will fail on these cars and it's just a matter of time.
If it's not failed yet I'd get preventative measure in place while you've got all the parts out the way. I know most of us say if it's not broke then don't fix it but this issue is very common among the e46s so as I said I personally believe it's just a matter of time regardless of the age of the car.
