Spotted these last night and was going to post up but forgot in the end I had a set of Armstrong discs on my 600 . I paid 280 odd for mine and they where stunning . Very good quality Originally i bought a cheapy set form a uk company that offered a 3 year warranty which i thought pointed to them being good but when they came they looked cheap and nasty and where way to thick and rubbed on the callipers , I didn't notice the rubbing till i got a few hundred yards down the road and the front locked up from over heating . Sent them bad k and got the armstrongs Top Quality ..
I bought a pair of the WRP disc's from ebay the other day and thought they seemed cheap, now i'm thinking about it i'm wondering how heavy they are compared to the stock disc's!!
