BBS RS offset required to fit a Big Brake Kit (Willwood) on a Miata?
I've seen some pics of BBS RS with Big Brake Kits but no lead as what the offset are. Also most I've seen are not on our cars. Does anyone have any lead as to what would be the minimum offset required to fit a BBK (wilwood) on a 2 pc. BBS RS on a miata? Thanks in advance.

You need to measure the distance from the rotor hat to the furthest point on the face of the caliper. You also need to measure the radius from the center of the hub to furthest point of the caliper's edge. Not rocket science. You also need the wheel's back spacing.

You do see the image I posted above, yes? Back space=rear space. Seller needs to measure that. A caliper, a ruler and a piece of cardboard, a combination of such. A seller that doesn't have that info or know how to measure it isn't worth buying from.
