Lol took you long enough, yes.
Have a read at this regarding the federal rsr, not slating them at all but just FYI.

In 2009 the RS-R was considered, and fell under the jurisdiction of the Federal Motorsport tyre department and was sold only to specialised motorsport tyre dealers. In 2011, because specialist tyre sellers were not shifting enough products globally it was removed from motorsport sales and became a UHP tyre and sold to European wholesalers. However to make the price reasonable in the very competitive market a lower specification tyre was made to be sold to the wholesale market. Tyre sales are very competitive and if mainland European wholesalers were getting a significantly lower price than the UK, then the UK would be up in arms over it and you would not see RS-R's in the UK. The reason there is such a significant difference is that the UK motorsport dealers pay more for a higher specification product. If we could get the product we do at the Euro price we would be selling at a much lower price also, that is market forces. The fact we don't is because we get the higher spec product that costs more.
And no, there is no obvious side wall marking difference. The lower spec product is lighter and if you move these tyres around all day you will know a light on when you come across it, the rubber is also a different colour.
If you look at MyTyres or any of the other discount dealers you will frequently find RS-R prices lower than the standard 595 budget option. There is absolutely nowhere near the margin in a tyre to be able to cut 20 to 30% in price unless you are buying a cjheaper product inthe first place.
