I also have the FK coilies, and even though they are soft, they are alot better than standard boat factory suspension.
I know i'd rather have a nice ride than having to get a new spine every time I went round the shops.
Once you lower them a bit more, the ride gets a bit better I have to say.
I'm very happy with mine, and even after being in a mates car with the harder JOM coilies, I wouldnt change them.
