Questions after installing (one side) MAP trailing arms
For those of you that have installed these things, I have a few questions. dumI installed my passenger side arm the other night (ran out of time to do the other side) and I had a few issues. One was that I could just barely get the cradle to drop enough to get that mile long bolt out. I started with just the forward cradle mounting bolts undone (both sides) like Adam's how-to said, but I wound up having to drop the rear cradle mount bolts too, AND I had to pry like hell with a crow bar whilst trying to work the bolt out with my free hand. dumIt wasn't much fun, especially putting the new arm back in with only 1 hand.dum
I was worried about damaging things from pulling the cradle down so much, but since others have been problem free in that respect, I just reefed as much as necessary. dumI kept an eye on a brake line that I could see, but otherwise I didn't know of anything else to watch for.dum
My other issue was with the clearancing of the strut mount. I had to grind off significantly more than the 1 or 2 millimeters that Adam suggested in his how-to post, and I think the arm is still making contact with this area. Anyone else encounter this?

New extra clearance
Other end

I found when i installed my BMR trailing arms, that the cradle was hitting the exhaust, once i took that down, it made it where the cradle could come down further.
That area you clearanced should have no effect on strength really, taking a corner off like that should be fine

It's still touching though, and I'm not sure if it needs space or if it's fine as it is. I dont want it knocking when I go over bumps, etc, ya know? I also don't want any of that binding against any movement of the arm either. What'd'ya think?

Does the gap between these parts change as the suspension moves, or is is it petty much static? When it was still on jackstands, there was like a half millimeter of space. I feel like maybe there should have been more...?

Yah, it's definitely clunking/rattling a bit when going over bumpy/cracked roads, so it needs more clearancing. Certainly not the 1-2mm that Adam had suggested to remove in his 'how-to' article. Maybe I'll try a grinding disk rather than the cutting disk this time...that'll take a quick bite out of it. haha

Got em done today boys, thanks for the tips. I didn't wind up disconnecting the sway bar links, but the driver's side was definitely easier. I totally removed the front cradle bolts, and loosened the rear cradle bolts to their last few threads. I still had to pry the cradle down with a crow bar, but it was easier this time for some reason.
A CAUTIONARY WORD: MAKE SURE YOU DISCONNECT THR BRAKE LINE BRACKET IN THE PASSENGER SIDE WHEEL WELL BEFORE YOU START PRYING/PULLING THE CRADLE DOWN. I noticed the lines getting a little tight without this bracket removed from the wheel well.
Anyway, all went well. I shaved some more material off of the passenger side shock mount, did the same to the driver's side, and also had to grind a flat spot into the front cradle mounting bolt washers to keep them off the arms.
After this and the soon-to-be-known 'edmod' (3/8 rubber homemade 'washer' under rear spring perches to boost up the 'too low' H&R's), everything is awesome! No more 'reverse rake', no more fender rubbing on tires, no more wheels rubbing on trailing arms, and no more crappy feeling cut OEM springs.
