Gotta wait for the RSB though so it can go all at once. 3 day free shipping from Germany for these , incredible.

Since you are waiting, might as well order a set of beefed up adjustable endlinks too. The stock parts won't hold up well with a big bar.
While you are at it, a set of adjustable camber arms and toe bars so you can actually do a proper alignment wouldn't hurt either.

Thanks any suggestions on parts? Actually just got shipment confirmation, so instead of a few weeks it will be soon.

FYI, SPC rear camber kit comes with adjustable lower control arm and toe kit for cheaper than buying megan's arm and toe kit together.

You just need to make sure you buy two of them.

Been running my Koni FSD's, Racing Beat springs & Progress RSB for the past year with no problems. Those other parts would be nice to have, but aren't a must-do, IMHO. Maybe they're needed when you do the bigger drop with the H&R's?

No they aren't a must do. However, if you want to do a better, more performance oriented alignment, you do need to have separate camber/toe adjustments. Factory alignment specs are ok for a daily commuter but are a compromise between the two at best. It makes a big difference when you can actually add a bit more rear camber and still be able to keep the toe where you want it. Can't do that with the factory parts. Your tires will thank you for it.:smile2:

When I first got lowered in April with Corksport spring, JBR Rear Sway Bar and Koni Yellows, I had to upgrade the endlinks because my rear driver broke. I ended up going with Moog and they have been great. I switched to H&R in June and now, just today the Koni Yellows and H&Rs are gone.............and BC Coilovers installed.

My ride was just too bouncy and jolting and jarring. Can't wait to get the car back and drive her. She's on her way to me and my friend who did the install says it rides so nice. Very little bounce and comfortable.

I may go with the BCs, I'm not pain when it comes to vehicle ride but Springs are beginning to seem like too much of a compromise when it comes to actual performance overall. Experiences with other purchases are also telling me not to settle without considering options. Don't know how many times I've seen threads where people go through different Spring setups only to change. Thanks for being guinea pigs guys. >

I may have to wait a little longer but at least I can still return the H&R now, and I'll probably at least pick up the end links.

The biggest issue is not shocks, and is not springs. The issue is in which shock to use with which spring. I have heard a couple times that H&Rs when paired with Koni yellows make for a bouncy ride. I have H&Rs, but chose to go with Koni FSDs in combination with the Progress rear sway bar set to full stiff. This combination makes for a ride that is a bit firm but not bouncy or jarring. You definitely feel large bumps or holes, but that is due to the spring rates. You can't get around that no matter how much you spend on your suspension. Performance springs ride harder than OEM. I find that this setup gives you more than enough performance for any kind driving you would be doing on the street, and probably good enough for some track days or AutoX.
I looked at the BCs too, but the spring rates left something to be desired. The ones I saw had very soft rates in the rear as compared to the front. Unless you are running a really big rear sway bar, this could make for a bit more understeer than expected.
As I see it, there is one difference between a coil over suspension a spring / shock OEM type suspension- Coil overs have user adjustable ride height and dampening. High end coil overs are a lot more expensive too. Other than that, if you are going with OEM or slightly higher spring rates for ride quality reasons, coil overs are a wash.

Hmm I see, may also consider the Fsd. Like I said I'm not a huge pain about ride quality, but I would just rather not be bouncing around. Don't really need adjustable height as HRs from what I've seen have the vehicle sit where I want.

@arathol Did you need to cut the stops on the fsd?

@arathol Did you need to cut the stops on the fsd?

Yeah I cut them about an inch. I don't think it was necessary though. The car hasn't bottomed out yet with the H&R springs and didn't before I trimmed them either.
