calipers and brake upgrade

[joyaux]

I have a 66' 911 that is upgraded w/ bilstein 3 1/2" struts, and I have purchased the vented rotors for front and rear. I will be using the car for racing in HSR or similar and wondering what calipers I should use.

I have heard the 911S aluminum calipers are not great for racing, let me know what you think, and if you have any calipers for sale.

thx,

paul

As long as you have the late struts w/ 3.5" mounts then you are only limited by your class rules. The S caliper on standard 282.5x20mm rotor is good, better is the '84-89 Carrera rotor on 282.5x24mm rotor.

Be sure to use a 19.05mm master cylinder.

You will also want to use a '70s style 911 M rear caliper and 290x20 vented rotor. I am not that familiar w/ the really early cars so am not 100% sure what you have stock

The S calipers are said to flex. They are nice and light tho.

Pay attention to air flow ...
