Drill bit size

[69veedub]

I guess I dont need to buy new rotors and drums, it turns out my tuner lugs are 12 x 1.5 mm. So it turns out i have enough clearance to drill a 5 hole bolt pattern in my existing brakes. So now I have to figure out what drill bit is needed for the 12 x 1.5 mm press in studs.

also.......... offset every other hole pattern, you need full coverage over the brake pad area

According to product detail shown on Aircooled.net, drill out the lug holes to 9/16" and then drill to 37/64"

That's for the 14mm studs they're selling, not for 12mm he's asking about.
