I was talking to a chap at AMD and he was sayin of the KW/Weitec/AP range they sell (all made by the same company) the AP's are the most comfortable so you may find paying more or for a specific brand like the AP's will give you low and comfortable ride.

The trouble is, when you wind them low, you run out of travel on the dampers...and run on the bumpstops.
This gives a rock hard ride.
Unless you are spending over £1000, you can't get low, with damper travel...the cheap coilovers just aren't well enough designed or built to allow both.
If the OP doesn't want it to be solid...raise it a bit.
It'll handle better too.
