i have these fitted (for about 4-5 months i think) so i can give a proper opinion. ride wise they are ok, they are smooth and not too rough/stiff, just remember they are budget and are set at a happy medium, if your used to being able to adjust higher end coilovers these probably arnt for you. They will get the front low but the rears caused my car to sit un level if adjusted equally and almost as high as stock on the lowest setting so i now have one adjuster cap with no winder on one side and only the spring on the other side, its quite annoying... ive wondered why, possibly badly matched spring rates, dont know if its just my set. unfortunately for me i bought mine on ebay and didnt fit them for a year and they came from germany, pretty much no chance for me to complain.
i drive pretty spirited at times and regularly have the car understeering and over steering on private roads and i have no complaints with on the limit handling, it settles nicesly on hard cornering.
in my experience they ride better than fk i had on a mk3 vr6 several years ago.
what i will say is if you have a relentless 3inch downpipe and sports cat it hangs alot lower than the stock pipe and it takes alot of hits once your lowered.... speed humps now suck!-)
