Vintage FF brake question

[CARSHouston]

What year were alloy brake calipers first allowed in FF.
Thanks

I think 2011

The FF rules for the Vintage organizations I've seen typically specify steel calipers.

Thanks, on the 2011, but it depends on the vintage group you're racing with. One group I know of has 3 FF classes, allows engine rules to 2015 in all and class rules up to and including 1994. They break down as 72 and earlier, 73 to 81 and 82 to 94 and allow the aluminum head in all three classes. They don't specify the caliper material, but I didn't think they were allowed as early as 94.
