Broken Front Wheel Studs

[Shadylane]

I checked the hub size compared to the wheel size, there is a difference however the wheel has a small step on the inside to accommodate the hub (see picture). I removed the hub and bolted it to the wheel it fits just fine, no binding or tight spots.
Original un-modified Aerospace hub. I purchased them new.

Studs are Moser's not sure where they are made. I have ordered a set of Mark Williams which are manufactured by ARP. I always lock tight the studs on the hub as they are a true screw in stud without a head.

I do cross my tie downs on the rear but not the front, didn't consider that might be too much side load.

I made sure the small bolt pattern on the wheels matched the small bolt pattern on the hub. Fit is good putting the wheel on the hub.

The first 18 months I raced the car there were no issues, then boom.

Lot's of good ideas from you guys, I'll keep looking.
Thanks
