How does this redrill look?

[Idrisu]

Would this be safe to drive with, daily?

Looks great. I'd use them. Make sure to ask him if any specific lug is required to use because of how close the drills are to the cap lock thing in the center bore. Might need tuner lugs.

I dont know man those would make me a little nervous being you have halved the amount of metal between the hub bore and the lug bore. Will they be ok, maybe, but that is taking a lot of the margin of safety out of the the equation, and seems like an area to watch for compression/stress cracking

[Matt-B]

Been on redrills for 5 years. I'm still alive.

Yolo?

[roguetoaster]

I'd drift that because of what Matt-B said.

[Dj Buttchug]

id drift it

Looks good to me. Losing material between the lug hole and the centerbore wouldn't have much effect as the load is in that direction.

I do agree that is not the dirrection of the bulk of the load, but when you put that narrow area under compression via lug nut/bolt there is not as much metal to take that load. There is not as much surface area to engage the face of the fastener on the center bore side of the hole there by increasing the load on the available surface area, and decreased material to absorb that.

I am not a metallurgist or an engineer, but I have seen some sketchy shit when you test areas like that, (in other types of applications) for weakness or defects after its been in service, as an NDE tech. Not on automotive wheels of course but there is a reason there is x amount of metal between holes on wheels. I would not be worried about out an out failure, I would be worried about stress cracking over time and use.

I hear you, though considering I see aluminum hubcentric rings I wouldn't worry about this.
My old filled and drilled 5's were put through 350wtq+ for 3 years before I sold them and were filled 'n drilled arguably worse than this - an opinion coming from the excess of material engineers we have here on r3v.
I also had hubcentric spacers for the wheels, 57.1 inner 72.6(?) outer.

I dunno about you, but I'm 100% an expert on metallurgy, but only when I see pictures on the internet with no measurements and no idea of material composition.

but there is a reason there is x amount of metal between holes on wheels.

From what I've gathered, wheels rely more on the amount of clamping force and static friction of the wheel-to-hub interface thing-a-bad-jig, more than a strength of the bolts in shear. Until you get to insane Hp or braking forces. Remember, you and only do about 1g in turing at the best. But a lot of force in stopping.
