Very cool. I went the same route for my Bug. Ended up going with the Wilwood brake kit from Flyin Miata. 6 piston up front and 4 in the rear. Havent had any issues so far. Not a bad price either. I am very curious to see the outcome of your a-arm design compared to mine. Lets just say my first set wasnt happy after it's first race.Mazda Miata front and rear spindles and brakes. The Miata stock brakes will get swapped out for the big brake kit later.
