Suspension Crossroads (C4S Cab)
it turns out that one is my front strut mounts is broken/worn/loose. It needs to be replaced. With almost 70k on the car, it makes sense to install new components while replacing the mount. I have read a ton (thanks, Rennlisters!), & I still have a few questions. The obvious choice for me would be to go with Bilstein B6s or B8s on all four corners. However, the rears are backordered. From what I gather, they’ve been backordered since Aug 2017 & might be back in June 2019. I won’t hold my breath. Koni makes a sport rear, but they don’t make a front for AWD models.
Has anyone run Bilsteins up front & Konis in the rear? Sounds crazy, but maybe someone has found success with it.
I don’t plan to track the car & have no interest in lowering it, so I wasn’t planning on doing coilovers. It looks like some come with mounts & some don’t. Other than the common (& somewhat expensive) coilover sets, does anyone have experience with the entry-level setups? H&R makes a street coilover setup. Any feedback on those? https://www.urotuning.com/products/2...8aApRNEALw_wcB
What corners are cut on the less expensive setups?
As always, thank you in advance for sharing your thoughts. This community is great!

I personally wouldn’t mix and match different brands of shocks/struts on a vehicle.

What about the B4s?

i considered those. Maybe I’m looking at it wrong, but it seems like a lot of money to spend for stock performance when I could theoretically get upgraded performance for less. Is there a reason, other than the fact that they’re in stock, to go with B4s over 6s or 8s?

For not much more you may find some coil overs.

I wouldn't mix brands either. Bilstein B8's with H&R sport (lowering) springs. Gives you a great stance while retaining almost (a little stiffer/tighter) stock ride.

In my case, I have decided to go for RoW OEM springs, and I will probably go with B4 or B6 when the time for changing the shocks come. R&H will be stiffer and lowered more the car? Yes (and with the half of the cost of the OEM), but is not what I was looking for.
As I said, I love how well balanced the C4S factory RoW setup is for my use (ludic, but not track oriented)

I 2nd the coilover idea. I just did it to my C4S. They are fully adjustable so you could leave the car stock ride height. Then if you ever decided you want to lower it you can with only a few adjustments. Most coilover kits are fully adjustable so you can "dial" in the suspension from soft to firm.

Thanks to everyone for the replies and advice. I'm leaning toward coilovers at this point. Mbren1979 - which coilovers did you go with? What do you think of the ride quality? I'm thinking that the Bilstein PSS10s are the default choice, but I'm interested in feedback about other setups.

Based on a few threads and experience in other cars i am gonna go with the Olins street set up. Ill probably only do a few de days ever so i want a good street suspension. There was a pretty good thread recently on the olins. Many here have also gone with the less expensive options like Feal with good success.

I spent a lot of time reading about the BC Coilovers today. That is an intriguing proposition. I'm going to call them tomorrow to see what I can learn. It looks like they come with rear top mounts & I'd buy new top mounts and associated hardware for the front. From what I gather, that saves me about $500 from the PSS10s, too. The only real negative feedback I found was from some guy that (apparently) purchased a used early-2000s M5 with them already installed. It all started with a little clunk, and now it looks like I'll get coilovers on all four corners!

I have the pss10s on my 2000 and they are amazing.
I can’t attest to the other brand mentioned, but I can tell you that I’ve always had positive experiences with Bilstein product. I’ve use them on everything from street cars to purpose built race cars (rally). There is a reason they have the following they do. If it was me, and the price difference was only $500, I know which way I’d lean. Sometimes you really do get what you pay for. Suspension isn’t where I’d try to save a couple of bucks.
One other thought is to consider whether you really need height and otherwise adjustable coil overs at all. Unless you want to change height, or are racing (concerned with height and corner balancing), coil overs add a bunch of moving parts. So many people with street cars buy fancy suspensions and then set them once and forget them. Not really what they are intended for, and adds cost, moving parts, complexity, and additional potential points of failure. Not a big deal on a track car since you are constantly maintaining, checking and adjusting, but overkill for a street car. ...in my opinion.
The stock replacement Bilsteins are a great option for a street car.
