Ok, so I'm installing some Wilwood radial calipers on my XR4Ti.

The mounting brackets are aluminum with ARP bolts to hold the calipers on. Do I go with lock tite (blue) or Never seize?

Thanks!

In my experience, Loctite has an anti-seizing effect. I always use blue Loctite on caliper bracket bolts- they never loosen and come off very smoothly the next time they're removed.

Loctite will increase the break torque to loosen the bolts but subsequently they will, as Ross indicated, not be rusted and seized. Antiseize is probably fine with proper torque, but the temperature there is probably exceeding what most anti-seize can do (disregard the can label!). 

 

EDIT, Blue loctite is only good for 300F, so if it's hot enough to kill the antiseize it will kill the Loctite also.

Copper anti seize is what i would use.

I went to the Wilwood website, looked at a few installation guides, all recommend Loctite 271.

Next, you'll be reading the manual!

You shut your mouth!!

Ok, if the kit came with a manual, I would have read it but there aren’t too many off the shelf kits to put radial Wilwoods on an XR running Scorpio hubs.  Also the Wilwood kits use a stud with a nut while I have a bolt going into an aluminum mount.

ARP bolts are coated, nothing is required.

Would feel better if a stud were used instead of a bolt, it makes assembly and disassembly much easier given that every radial mount Wilwood I've worked with needed a bunch of shims to get the caliper location right.

Yup, I agree and when I get back from Road Atlanta at the end of the month, I’ll convert them over to studs.
