I have never owned a set of this (nor will I ever), but I have driven several cars (MkII's-MkIV's) with Racelands/Ultimos/Rokkors. These coilovers handle and ride like absolute garbage. Secondly, there are countless threads about issues people have with them. If you are interested in a car that handles and rides like crap, but is low, then these coilovers are for you.
My best advice is to find someone local (local forums, gtg, autox event etc) that has these or similar coilovers (Rokkor/Ultimos) and ask them to take you out for a spin. For comparison, find someone else that has a proper setup (Koni, etc. coilovers or a spring/shock combo that is at proper ride height). The difference should be very clear.
Threads just from the first page of the Suspension Tuning forum that are Raceland specific:
