I have a set of b4s with standard 6 springs that i got off ebay for £40 posted and they are like new. I will be puting my lowering springs on them as my currens shocks dont look that clean 
Also the b6 and b8 are yellow
Not sure if this is just rear or full set but have a look

Could even be for just one shock lol
