Anyone w/ experience with "Brake Performance"

Oh, and one other thing-thanks for bringing this to the attention of the board, both of you guys. It would have been easy to sweep this under the rug. Gives me a good feeling for using Lee's products, knowing that he backs them.

Again, sorry to hear of your problems Kurt, and I'm glad you and your car are OK.

Thanks Brian,

When you look at the RB rotor, it does look like the perfect solution for an E30, it even works with my Bimmerworld ducting (with just a tiny bit of bending to keep the backing plate from touching the rotor.)

I can't see how you or anyone else would have anticipated this failure.

I do have one question. I no longer have any stock E30 rotors lying around, but the hat on the RB rotor seems kinda thin. I'll measure the thickness for the RB hat but does anybody have the thickness measurement for a stock E30 rotor hat?

It appears that FM and Goodwin are using the RB 2 piece rotors, probably made custom to fit a Miata.

Not as helpful as I had hoped.

The RB hat material thickness measures 5.5mm

I don't have any E30 rotors laying around, but I do happen to have a stock style Corrado rotor (yeah, kinda weird) and it measures 5.25mm (.206") thick on the wheel surface of the hat. I can't get my caliper in to measure at the "window" area, but it looks to be the same thickness.

The Corrado rotor is used as an upgrade on many raced Golf and Jettas. So, it is not necessarely the Corrado design that is the problem, but the casting by a given company.

That makes sense that the RB rotor and an OEM style Corrado rotor would be similar. Its probably the fact that the RB face is painted black that makes it appear thinner. Black is slimming you know...
