i won't tell you what i paid for kw v1 as i got them from a good friend that import them in , but i paid less than £650 for them last summer
 
whatever you do just dont go for koni's you will have to buy another pair in a year due to wear and tare they are crap!!!!
 
i had kw v3's on mine and they were great, only got them as they were £750 with a set of neuspeed anti roll bars. only had done a couple of 1000 miles
