Funny...I just ordered a pair of those to mount on a set of cast wheels (with new tires) I picked up real cheap.
Should get them this coming week but interestingly enough, Arashi doesn't make a rear rotor for our bike so I'm getting a used one I had saved up.
I was a little shy about getting Chinese made rotors but I spent quite some time reading about reviews on them and feed back on various forums about people using them even in racing. Have not seen a truly worse review than Glfer or EBC so I pulled the trigger.
For less than $200 a pair...hell yeah!!
As for bolts, I'll need some since I don't want to disassemble my spoke SE wheels.
AF1 racing I believe have those for $2.00 a piece. Not cheap but I want to keep the original 10 mm hex head
In your case, I would feel plenty safe to re-use the original bolts because I can't see them being stretched at all with a recommended 15 to 20 foot pound of torque. And also, you're talking about a steel bolt going into alloy compound.
Just use loctite again with the appropriate torque and enjoy your new rotors.
