Re: Brakes That Will Stop A Freight Train
 

Nice rotors. Wonder if they make any for C6Z disks w stock offset? Those C6 disks are HEAVY!

Re: Brakes That Will Stop A Freight Train
 

ron and I picked up the c6 z disks and were shocked by how heavy they were

Re: Brakes That Will Stop A Freight Train
 

OMG. Love it Cliff!

How much for C6 Z06?

Where did you get those, they are gorgeous!!!!

Pretty massive. No way those babies are warping. Don't forget, they're 14" across.

It has been so long since I changed over...What are your impressions from J55 to C5 brakes?

and those are some trick a55 rotors you got there. I thought my black anodized EBC slotted units were pimp.

Re: Brakes That Will Stop A Freight Train
 

I have this same Wilwood SRP Drilled Performance Rotor brake set up on my 91' and I can tell you there is no fade.

Also the Bearing Hub does not see near as much heat on a high speed stop.

The trick with the Wilwoods is the Hat. As you can see there is limited transfer of heat possible from the Rotor to the Hat. That keeps the Hub cooler than a solid mass Rotor/Hub. So the front end Hub Bearings do not see near as much heat when I stop in my relatively short 1/4 mile runouts from 120 mph :p

I will let you know when I get these installed on my 90' how pimp they are after a few 1/4 miles high speed stops :D

Re: Brakes That Will Stop A Freight Train
 

love the wilwood stuff. I have the 6 piston superlight calipers and 14" rotors on the c5. stops so hard it will make your eyes pop out and tough flap horizontal

I like the Baer alcon on the LSV, but they are 4 piston calipers, and the 13" rotors are toast. worn so much the grooves are GONE

I worried about it until I called Baer, the rotors are so thick that shaving that much in wear off either side is no issue. I was above the min recommended thickness even with all the wear

however, they will need to be replaced soon. looking hard at this rotors. very nice stuff! I want the silver plating though.

Re: Brakes That Will Stop A Freight Train
 

I lust for hat rotors in j55 size but I can't find a recipe. Your brake porn is a natural progression from there...

Congrats, nice setup.
