Wilwood 14" 6 piston brakes vs. Z06 14" 6 piston brakes- 3800lb 800hp+ Chevelle

[gnx7]

I posted this up in another thread.... but it went unanswered for 2 weeks.

I need to put some front brakes on my Chevelle. Already have the disc/parking brake drum combo from Wilwood out back 12.19".

Is the cost of going to a 14" front brake worth it? I'm guessing the car will be around 3800lbs.... hopefully less. Alum turbo'd 5.3, T56 Magnum, Quicktime steel Sfi bellhousing, 50lb twin disc clutch, heavy 35 spline 9", full cromo cage, heavy CTSv power seats, a/c and p/s with 25 gallon s/s fuel tank and 10 gallon a/w intercooler tank in the trunk and 12" subwoofer box. I have the ATS front spindles with ZR1 hubs on the front and custom JRi coilover suspension we are fabbing up.

Looking at Wilwood 6 piston 14" fronts.... are the C6 Z06 vette brakes cheaper and just as effective in braking power?

Z06 front rotors are $90/each to replace. The calipers are $800/pair
There is some hardware also needed (pins etc) maybe $80 worth of parts.

Mainly I'm going to be street driving this car.... doing a couple drag race days per year (9 second goal), and a couple track days/AutoX.

It all depends on what you mean by a couple track and autocross days.

If you want to push the car on a track, it doesn't really matter if you are doing a couple days, or a bunch of days. In any case, prep and pad selection will be more important than which of the two choices you decide to go with.

In my previous RX-7 I ran a 1:35.5 at Laguna Seca my first time there with about 40 minutes worth of track time... so whatever is driven.... does get pushed hard.

Who runs either style front brake on their car and what is your feedback?
How often have you had to replace the rotors?
What respective pads do you run?

Looks like the replacement rotors from Wilwood are about $250/each
And the kit for non cross drilled with slots is around $1800

On the Mustang track car we run a Wilwood 6 piston Aerolite with a BP20 pad -- and a SPEC 37 Rotor. Rears are 4 piston Superlites with a BP10 pad. This is a "softer" pad -- and a harder rotor... so I'm not chewing thru rotors like I used to with the more aggressive pad I used to run to get the car to have some brakes (old 4 piston front and single rear) and the cast iron "standard" rotor. However -- my car is 1000 #'s lighter than what you will be according to your 3800 # guesstimate.

I run the car hard and haven't had ANY brake issues.

Since both the Wilwood Aerolite or the C6 calipers will get the job done. You pretty much just have to decide if the lighter two piece Wilwood rotors are worth the extra dollars. I would also go to either the Camaro or Shelby SVT performance forums and see what pads the newer, big 3800+ lb cars are running. I haven't been able to find a Wilwood pad that I am really happy with compared to some of the other choices. I won't go into detail unless you ask, but just say no to the BP20 pads on your car.

I'll have to ask my buddy that races Corvettes which I know are 600lbs lighter... to see how factory rotors hold up.

Anybody warping stock Z06 rotors and/or the Wilwood ones? I will be running an aggressive pad. Thank you for the input Matt.
