So finally bit the bullet and treated myself to some Bonamici rearsets and some brake pads for the 999r. Scoured long and hard and found this place and with their 10% discount, the prices seem keen across the board https://www.drbikes.co.uk/ No affiliation other than hopefully being a happy customer when the items arrive next week.
Make sure you confirm they fit when you receive them. I bought a set of Brembo callipers for my R1 off him a few years back and they didn't fit without modification. I ended up having to get a different front fender, spacers and bolts because he wouldn't exchange them for the other ones that did due to them being past the return date (30 days). I ordered them at the start of December and decided to fit them just after new year when I was off work. He was a total prick to deal with saying he never actually said they would fit even when I sent him the screen shot of his message saying they are the correct ones for the R1, I offered to pay the extra and get the more expensive set that would fit but he refused to do anything.
