I know this is a prelude forum. However, I know you guys have upgraded to legend/nsx rotors and calipers, so I figured some of you maybe able to shed some light...

I'll be redrilling prelude vtec rotors to 4 by 100 for my db8 and use them with legend calipers and caliper brackets. i'll be machining down the insides of the caliper brackets probably 2.5 to 3mm. anybody know if there's anything i can coat the new holes with to prevent any cracking from hole(s) to hole(s)? Thanks.

 

you shouldnt have to coat them with anything, theyre fairly soft as is so they shouldnt crack. theres nothing you could coat it with either that would keep it from cracking anyways.

 

thanks
