I have removed the subframe nuts from numerous M Coupes/Rdstrs now, and the ones on this Coupe were the tightest I've had to undo. Possibly the tightest fastener I've ever had to remove!

I have an Armstrong 4:1 torque multiplier. You would normally use a tool like that, for example, if you wanted to put 400 Lbs/ft of torque on a fastener and only had a 100 Lb/ft torque wrench. But it also works to remove fasteners, and this marks maybe the third time I've used it in twenty years! The breaker bar and "cheater pipe" had no effect whatsoever. I had to use the breaker bar AND the torque multiplier to "crack" them loose, then I could use the ratchet on the tq/mltplr. The right side came loose with "only" extreme force on the breaker bar.





Oh, okay, here's a couple shots of the car too...





Note too, that I had to replace (and reinforce) the swaybar mounts on the body and reinforce the tabs on the trailing arms. I'm open to suggestions as to what I should use to "touch up" the plastic coating on the trailing arms. I thought about that stuff you dip your tool handles in, but I question its durability.
