nice, but GAZ can do you a fully adjustable coilover setup for around £650 (strut exchange) thats included rear strengthend shocker mounts, bump,rebound,damping,height adjustable, its called the "Gaz gold" range, for track and road usage, but you can specify what you want with custom springs rates and what sort of motorsport you will be doing

and if any of you watched the top gear when they entered the BMW Diesel into the 24hr brit-car, they set that up with their coilover systems
