I mounted the sliders on the rear bolts 3.5 inches - 88mm long on both sides.
One on the left sticks out a little more than the right, about a half inch - 10mm
I don't know metric conversions very well, I hope this is correct.
I also bought the first set with a 10mm hole, ---- I had to drill them out to 12mm
HINT: Pop out the aluminum plug to drill or it may just spin inside the slider while drilling,
- or - make sure you buy sliders with a 12mm hole.
I mounted the ones below on my girlfriends 05S3 on the bolts behind the radiator.
Sliders are 4 inches - 101mm, on the left side , and 2.5 inches - 63mm, on the right,
bolts just behind the radiator.
" These measurements are approximate ( don't have bike here to measure ) "
I bought some sliders made for a 98 Yamaha R1 ( I think ) with 12mm holes, for around $50. at cycle gear.
They just looked to be about the right size and I didn't pay attention to the package before I threw it out.
All I was looking for --- sliders with a 12mm hole, and one slider needed to be longer than the other a half inch -10mm approximate.
You will have to buy bolts that are 12mm fine pitch threads, and I don't know how long, each side is different, you will have to measure.
NOTE: if you use the rear mounts, the left side with the aluminum triangle motor mount. -- there is an electrical connection JUST behind the bolt.
If the bolt is too long it will CRUSH it, I had to grind the bolt a good bit to avoid crushing.
They look great , and mine have been tested

( Too stupid to talk about )
good news - had no radiator damage,
Bad news - broke turn signal lens, and broke off brake lever, bent in the foot brake,
( bent it back out) and scuffed the clutch cover.
If I do mine over, I will mount behind the radiator.
