The packaging was OK, not great, not terrible, suspension came undamaged.
No instructions were included, it wasn't a problem for me but some less experienced enthusiast may find the process a bit difficult without counsel. Especially on how to correctly jack up the car safely to avoid dreadfull accident if the car fall on someone.
Installation and height setting went flawlessly, no difficulty at all, the height range of the coilovers is impressive !
Build quality is nice, the collars to set the height and preload are sturdy enough to not get chirped ou scratched as soon as you tighten or loosen them.
On the road I began full soft to see how they behave and start my way there to set them up. Surprisingly out of the box the valving is the best I've encountered to date. It's not perfect but the car is comfortable, coilovers have plenty enough of droop to allow the tire to always be in contact with the road even on very unsetlling roads. While being very good the valving is still too soft on the rebound as with all coilovers. The hydraulic doesn't slow down the rebound enough which make the ride "bumpy", it's usually very bad on a lot of coilovers I have seen/had/driven. On those CEIKA it was surprinsingly good, but not firm enough, I had to add 7 clicks ont the front to get rid of the rebound, but it made the ride stiffer on compression and so less comfy. It's not a problem on well paved road but for less good ones the car is then less predictable. It still hold its line and absorb a lot of the irregularities of the road but I have less trust in the grip that way.
Compression is okay, the stiffening work perfectly fine when I go toward the hard setting, it's really the compression/rebound ratio which is a little bit too soft on the rebound side. You need to have stiffer rebound setting to slow down the car when it come back.
The rear was almost perfect, I only needed 2 clicks to stop the rebound from being annoying on the speed bumps and stabilize the rear...
CEIKA Type 1M Coilovers for Audi A8 D3 (02~09)
I am overjoyed that I bought this custom suspension for my car. It's hard to find upgrade parts for a Q70L but Ceika exceeded my expectations. I love the response and the adjustability within the dampening. Having the double springs upgrade was the way to go! This feels better than the factory setup! Oh yeah, the 3.5" drop on my ride gives it a whole new stance!
With prior experiences of getting coilovers for the wrong car when buying from a cheaper suspension company, I'm really glad I ponied up and spent what I did. 1500$ is a hard pull to swallow but entirely worth it for adjustable camber plates and suspension that looks and feels the part while doing an excellent job. There were no instructions in the box but it's really simple to just match the part with the one you're pulling out. Do a bit of research to find the torque specs on your specific car and you'll be golden
I went from 30 year old floaty stock suspension to feeling better than my friends new bmw. The installation took less than 5 hours, and everything fit perfectly. My favorite part is the tumability you get by having those knobs on the front and rear, I was able to change my car's tendency from understeer to oversteer.
