Congratulations on a great purchase!

Those shocks are very similar to the ones I bought for my BNR34. The difference is that those are even more expensive than mine.

The differencies are rather small between the models and I decided when I bought mine that the Flag-R weren´t worth the extra money.
£2500 will definetely NOT be enough to get you those shocks from Japan to the UK including customs and VAT. They cost £2600 in Japan... I´d guess the price would be at least £3800.

The biggest problem when I bought mine was that the shipping company wouldn´t touch them when they were filled with gas so they had to empty them and then I had to go to Ohlins in Sweden to get them filled up again.
I´m VERY interested in where you actually bought them since I didn´t get the English Mounting instructions with my set??
I looked at the Longacre scales aswell but just couldn´t justify the cost of them so I just used a measuring tape and it went very well. I checked the settings on a set of scales later and I was almost spot-on.
Yes, they bolt on without modifications. And Dino, if you ask me, these are overkill unless you do a LOT of trackdays every year. The "External reservoir"-type I bought will make you VERY satisfied, you´ll get both better comfort when you want that and racinghard setting when you want that. :smokin: All for less money.
If anybody´s interested, there´s pics of my set on the forum somewhere.
And if you have any questions, just ask. I couldn´t be happier with my set.
BTW, here´s a link to the Japanese Carrozzeria-page for Flag-R:
