Jay Laifman should be qualifying in the top 10 on the grid
In board or out board brakes.

I don't know the best sub forum to ask this.

We just bought an Elva Mk VI that has front and rear discs. We understand that the original cars came with drums all around - but the last factory Mk VI had front discs, so the historic racing groups allow front discs.

I think though that we need to convert the rears back to drums. Originally the drums were inboard.

Does anyone know if the historic racing groups care if the drums are inboard or outboard based on originality?

I'm assuming that for the racer's sake that in board is preferred since it is unsprung weight, and having them inward reduces their effect because of the leverage based on where they are on the axle.

Now of course I have to figure out all the parts I'm going to need for that conversion, and how hard it is to find them.
