Chris, do you plan on marketing on these calipers?

Here is video of cycle testing to geek out on. Brakes were cycled 40,000 times at 2x max operational pressure.



A few more brake sets are now available.

Attaching is some interesting data gathered during testing of the new calipers. This stop is pretty aggressive at 0.3Gs. Noteworthy is how little brake pressure is needed. The Matco master cylinders are nominally rated for 450psi.

I am in the process of assembling another batch of calipers. A few are ready to go now.

Only two sets left from this batch.
Another run is planned later in the year.

A few more sets of brake calipers are now available.

To repeat from above:

$950 + shipping


These are drop-in replacements for the single piston Matco caliper that came with the kit. These calipers are slightly lower profile and have a smaller outer diameter than the original. I have recorded a peak of 0.4 Gs with these units.

Chris these looks extremely well!

I think I remember they was little more heavy than the original kit breaks?
However seems to be a good trade.

Roger,
Correct.
Twice the piston area and twice the pad area. They are not quite twice the weight of the Matco calipers. While this might seem to conflict with my other thread "360 on a diet", this weight is actually providing big performance gains. I am never going back.....
Now if titanium weren't so expensive. :wink:
