I have a question for you. How did you motify your Extreme 2 to 510lbs? I've found 410 is also a light weight for exercises. Also once motified did you find any problems with the Bowflex? Was it too heavy for the machine? I appreciate you input. Thanks!

I made a steel bracket, screwed on to extend the rod box for an added 410 lb rod set (the one with the plastic bracket).
No problems.
I don't get do anything at 510 lbs that bends the rods all the way, so I'm not worried I'll break anything.
Works like a charm.

Could you possibly post a picture?
