Hi Pabloss, I've not heard of this brand, but I am also looking to upgrade. You only need coil overs if you want to fiddle with the ride height. You could just go for a normal lowered spring and uprated damper set?
If I was fitting coil overs I might bite the bullet and buy the Autodelta kit for £700ish plus vat. I assume it is this set you are looking at?? - which is almost as much as the Autodelta system anyway -
FK / Silverline Coilover Kits / Alfa Romeo 147 (Type. 937) GTA From: 03/02 > / Euro Performance Car Parts
The guys at Europerformance recommended this set to me as being perfect for the job and is not coil overs: -
KW / Suspension Kits / 147; (937) 1.9JTD, GTA From Years: 03/04- / Euro Performance Car Parts
If you buy the FK set up - let me know how you get on!
