Here they are in his catalog with tapered seats so you need to ask him if he has them in a metric thread?

Of course you could also go another route and just change out the metric studs for the US SAE versions? That might be more difficult to do? You would have to find the stud with the hub that fits your flanges?
That probably would be in Dorman for regular production cars? I don't know where you would get Grade 8 studs for racing in those or if they even exist? Can't help you there.
