Few option available,
the front brakes are the same as on Familia 323 GT-R aka BG8
Very strange in my opinion, the BG8 is something like 900kg in weight, but the Cosmo is a big 1650kg car sharing the same brakes. Mazda is known to build very well thought out cars, but the brakes on a Cosmo is what I can\'t understand.
just my 2p
