New XI Coilover option?

https://www.ecstuning.com/b-ecs-part...029310ecs01~a/

Has anyone ordered or received these yet or know anything about:
- warranty?
- rebuildable?
- includes adjustable sway bar links?

On their site they say they're for E90 but not compatible with E91? [I have E91 xi]. I was thinking of buying them anyway but not sure if it's worth replacing my current suspension for this...

Nice find, page says it doesn't fit E92 but I'm not sure that makes any sense. Price is very reasonable

My guess is that the spring rates are chosen for the E90, maybe they'll have an extra part number for the E92 with its lighter butt, or the E91's heavier butt.

Either way, these look super similar to BCs. Not sure if it's just a representative picture, but a "true coilover" rear is generally not a good thing on cars that don't have it that way from the factory unless there's a cage installed to reinforce the shock mounting points.

Wow really they gunna do us like that! I didn't realize there was a difference between the e90 and e92 suspension. This would be perfect for my brothers car and budget but he has a e92 xi

See, I think that because the spring rates are so much higher than OEM, they should really work on any of the E9x chassis. I know Fortune Auto does not distinguish between E90/E91/E92/E93, probably for that very reason.

I am more curious about the warranty that ECS gives and whether they're rebuildable. Not trying to have them 'expire' every 1.5 years.

Just talked with ECS and it's an error when it says does not fit a e92 awd. I agree they look like BC BR coilovers. I bet they just put in a large order from the same manufacturer

Just a branded Chinese coilover obviously. Nothing to write home about, but functional and an enticing price.

Will be very interested to hear a review once someone tries these guys out.

I've always been leaning in the direction of KW V1's but these are half price - maybe if they provide at least better than half the quality of the KW's I could be convinced.
