BPD posted a while ago about having issues with rear camber after installing lowering springs. He could not get back to OEM specs. But alas, he found a solution, thank you sir. My question: is anyone running into that same issue with Megan coilovers? If so, will BPD's solution apply? The dealer told me I'm very slightly out of alignment, but I want to wait until I install springs or coilovers. If I go with the Megan's, should I have the dealer do an alignment before or after the install? Much thanks.

ALWAYS perform the alignment after any suspension work is performed (including the coilover install), but IMO you'll want to do it maybe a day or so after so the suspension has settled to proper final height. Don't drive more than just a little bit, because you can eat tires up with way-off specs. When the suspension is dropped, the rear camber will come in aggressively, and the front toe will toe out aggressively. Both will eat tires for lunch.
So, after the suspension has settled, get your alignment done. REMEMBER that the rear alignment bolt at the top of the rear hub... it can be loosened but even dealers sometimes don't know this. My aftermarket shop had no idea, I had to show them the OEM manual data and even then they were skeptical. I said, loosen this bolt, and pull really hard...sure enough that trimmed the camber out. From the factory, the adjustment is full negative as much as possible, so when you drop the car you'll need to max it out the other way.
A little extra excessive rear camber may still end up in the system, but this isn't necessarily a bad thing. You may be familiar with people using extra rear camber to clear oversize wheels and tires, sometimes. Also, rear camber (without going to extremes) can help with rear grip in cornering dramatically. So, a tiny bit out of spec is OK overall, at least with camber. Toe needs to be on-point front and rear, and you want that accurate or you'll eat tires. Toe is highly adjustable front and rear on our cars.
Front camber is partially adjustable, but only positive .5 degrees per side and you'll likely not need to touch it. Again, some camber up front helps with handling, and big tire/wheel fitments too.
