thanks

Not thick enough.

.433 in

I am looking at another option that should be a bolt on upgrade to an .810 vented rotor and a four pot caliper. I'll keep you posted when I have the other parts to compare to.

Wear limit of brake disc (symmetrical wear)	9.5 mm	.375 in
Thickness tolerance of brake disc	0.02 mm max	.0008 in
Later wobble (deflection) of brake disc installed	0.2 mm max	.008 in
914-6 Front Brake Discs

how funny.....I spoke to a Wilwood engineer a few weeks ago that gave me a sneak peak (pdf file) of their new line of 4 piston calipers....

radial mount:

1.38", 1.25" and 1.00" bores available....for rotors .35/.50 and .79/.85 thick...diameter 10.25 to 11.00"....

pretty cheap at $150 each (forged as well)

thanks for the numbers Paul....

How about a bolt on 4 piston brake upgrade with an .810 vented rotor with a floating rotor, studded hubs all for less than 400$. You will need a bigger master though. Should know something in the next week or so.
