I was told the K rating wasnt any brighter?  it was just the colour "temperature"

Seing as all new cars are factory fitted with them to blind us i think we have every right to ave em!

Yeah K = Temp but it can also dictate how bright it is. I.E the 4.3k is slightly yellow and produces a slightly less amount of light than the 6k whiter light.

You may find a slight blue tinge to a 6K set, they do vary but for the most part they are white. Makes a massive improvement.

I would be well up for a set on my quads as well! Possible group buy?

4.3K or 6K.

I have had problems with cheap kits from eBay but others seam to be good. All depends on the seller. I would try and go for the sellers from the UK rather than the Chinese sellers that take 4 weeks to get your item.

spot on 

for ref, my mk 4 which has Xenon as standards, are 4k or 4.3k to be exact, this is what most manufacturers run OEM

got 6k in my mk 3, not much in it tbh
