Floyd mate, when you first fitted the coilovers to your car, you were quite literally driving around on the bump stops. Dont you think thats a bit stupid?
Drive your "slammed" car down the A701 that i frequent every other week then tell me it handles well! Because its a real road, that needs a car that actually has some suspension travel otherwise you'd be bouncing off the stops every 30seconds and probably wreck the car or suspension in the process. In my car its fantastic fun, 50+ miles of proper decent twisty windy road that you can have a blast on.
My cars lowered, but its lowered a sensible amount then means it remains usable and can be driven properly. Cars like that golf pictured above, or ones slammed as much as yours was when you first fitted the coilovers simply arent useable, and most certainly do not handle well.
