Well if its built for that much power why is it clunking and banging, sorry but you asked for help and a couple people offered advice and your sounding like a dick now.

Check your trunk, a loose spare tire or battery could be making the noise

And it's not the actual subframe that cracks, it's the mounts in the floor they bolt into that rip out, even if you had the m3 style reinforcement plates welded in, if they were loose and not properly repaired they can still make noise.

Also curious to what your putting in the car that you think you will have 600 whp?
