Jackass w/ LS9: original build and new Jackass 2.0 updates!

[rwhite692]

GM's MSRP on the ZR1 brake components is $12,183

Gene Culley is currently quoting $8,999

This includes four calipers, four rotors, 4 sets of brake pads.. (ZR1's are 1 set of brake pads per wheel, and the calipers and pads do not come with the caliper pin kits.)

Some are of the opinion that these brakes, if not used with the corresponding electronic controls, might not perform all that much better than the current C6 ZO6 setup (as Scott has on his car).

There just isn't much data on how they would perform when retrofitted to something like an older musclecar, and operated without the controls... yet.

There are definately lot of things to consider, apart from just bolting them up...of course you need at least a 19" wheel...

Here are a few, from the Corvette Forums:

Be aware that if you track a car with Carbon/Carbon or Carbon/Ceramic brakes you MUST use/make further modifications due to the higher operating temps.

The ZR1 required different front spindle bearing assemblies, due to the extreme heating generated in the rotor. So, plan on changing hubs and spindles.

The brake fluid used MUST have a DRY Boiling point above 600*F. There are ONLY 3 choices currently available. WET boiling point is a concern but is secondary:

Make / DRY BP F* / WET BP F*

AP PRF 660 / 608*F / 390*F
GS 610 / 610*F / 421*F
Wilwood EXP / 626*F / 417*F
