Rear Caliper bolts

[Julian Hands]

I purchased from PRO-BOLT some titanium replacement bolts for my 2018 MT09-SP but after installation noticed that the protrussion length of the bolt head doesn't fully clear the caliper casting and each bolt heda then knocks the caliper, do I need to grind away the caliper to allow clearance or are their better bolts out there that install without issue?
Any help appreciated as my old bolts have corroded and look terrible, yet have had to re-install them due to this issue.

Have you contacted Pro Bolt concerning this issue?

Sorry it appears that the bolts are OK, the rear wheel bearing however is showing a little movement that has caused this mis alignment. Bearings on their way.
