I've managed to get an entire rear M3 subframe (diff, brakes, roll bar, the lot!)
Rather than removing the diff and drive shafts for installation into my 335i, can I just swap over my 335i hubs and brakes onto the M3 subframe and fit the whole shebang in one go?
YES DO IT
i have done it, it only needs a custom drive shaft and the m3 springs + dampers
go with h&R M3 lowering springs all together, due to less weight the 335i will sit higher than the M3 wit the oem M3 springs
