I'm trying to RAISE the suspension from OE position on my 3770 lbs wagon.
That's before it gets loaded with people. Factory dampers are OK except rear passenger side. They will all go out soon. The car is at 62k miles now.

Which one should I get between Fortune Auto 500, BC Racing BR Series, FEAL 441
Fortune Auto is 8k/11k stock but can be switched without extra.
BC Racing BR series is 6k/12k and seems ideal to have more spring in the rear for added weight but front is too low on spring rate vs the back.
FEAL 441 is 8.5k/11k. I like the front rate but the back rate is not high enough for wagon duty. Seems like they were made for sedan.

For height adjustment I'm hoping to get threaded body that can adjust independently without loading up the springs. FEAL and Fortune Auto 500 advertise them as such.

All of them are similar in all other specs except Fortune Auto 500 that is "Fits Wagon" while other two says "Does NOT fit wagon". I know they all use the same mounting for all xDrives, so maybe it has to do with spring rates and damper valves to control the springs?

Personal experience inputs are appreciated. Thank you.

BC adjust separately too. If you can confirm BC fits wagon (I think it should) I'd probably get those with custom spring rates.

I run ST Coils on my x drive e91.
Love them!

only ever used KW products...

KW seems too expensive for each level they offer. And I have no idea on their spring rates. I don't trust kits that won't show their rates.

I don't believe BC customizes the valving for each model or do they? I know for sure ST / KW / Bilstein does

From my understanding, BC has like 3 valving setups total and then figure out which works ok per application.

I would go the ST/FEAL.

Spring rate is one thing, damping is whats more important

Thanks, I'm thinking FEAL 441 as well. There are others like Fortune Auto etc but I don't think they will do much better while costing about the same $1,500 range with complete hardware like sprint mount bearing for front.

I'm on BC with the stock 6k/12k on my e91 awd.
I wish I changed the spring rates when I purchased my coils.

What are those rates like over bumps and cornering?

Which rates would you have gone to control the body motion?
Damping is for the ride quality.
