This fit my 2009 PFL sedan with no issues. I don't believe there is any difference between PFL and FL back there.

Also fit my 2011 just fine as well, did it about 2 years ago. When you're loosening the sub frame you're keeping it lined up right?
That's the only issue I had was I had to support subframe a smidge to get lined up.

Interesting responses. Do all of your bushings look like the pic below? Because my bar won’t fit without some serious grinding out, and even then I’m not sure I want to eff up the integrity there. It won’t fit anyway because my diff cooling pump is now squarely in the way so may be for sale soon…

The two other little pieces that attach to the front subframe did also not fit as the hole was not big enough for the bolt but I can enlarge that. This also was the same reason the front Spoon Ridgid collars would not fit.
If the subframe bolt is the same on the rear as the front that may be my issue with the rear bar as the the front spare subframe bolt I just bought doesn’t fit through.

My rear subframe bar is exactly same issue as BLKROKT the circled ends of the bar do not fit inside the subframe bush. They are about 5cm away from dropping down into it as they touch the sides where you can see screws go into the subframe bush.
also more pictures of the front small bars, the small square part on each bar where the front subframe bolt goes through is too small.
The two smaller bars I can get the hole machined larger but the rear subframe bar you would have to cut up the end cups!

The subframe is a huge chunk of steel.
Does it really need another, smaller piece of steel bolted onto it to make it stiffer?
Or is this thing supposed to somehow use the bolts to counter the flex in the subframe bushings?
Or are we just buying stuff for the sake of buying stuff at this point?

exactly. The subframe bar is pointless. Connecting one part of the subframe to the other? But the subframe is a huge piece of steel. Truth be told the only bars you need are the front and rear strut bars. Everything else are just replacements for bars the cars already have.
