Front struts on the H&R don't come complete, the OE "hats" need to be re-used. Doesn't come with end links either, you may or may not need those if yours are worn
If a shop was working as fast as they could, I bet they could have these out in a couple hours, but you're likely looking at 4+. They'll be taking their time and looking for other things I'm sure. Hack mentioned this too, you'll also need an alignment.
I was able to do mine with just 2 compressors ($30 from Autozone), and I don't recall having to modify my RSM's to get them to fit. I definitely remember that the "roadster trunk woes" are really overblown, but maybe it helps that I have small girly hands
If you're looking to buy the H&R's new, you can save a few bucks from Turner if you put them in your shopping cart and start to check out but don't finish. After a week or so they'll send you an email to finish your purchase with a 5% discount promo code, good for ~$60 on this.
