Default Wilwood Aero6 Calipers and C6Z Rotors?

I may have missed if this was asked in the past.

I purchased the Aero6 spec corvette setup with fixed 14" rotors and aluminum hats for my C5. Can I run the stock 14" C6Z rotors with that setup? Do they have the same offset as Wilwood?

I'm thinking of carrying these as spares as it would be quicker to change out at the track versus bolting / wiring the hats. But only if I don't need to re-shim the calipers to be centered on the different rotors.

Do the stock rotors give up a lot of life compared to the non-floating Wilwoods?

Thanks

Rob

AFAIK not if you have the 20mm pad kit. I purchased the 17mm kit so I could run c6z rotors mainly for the easy of spares.

how do you like the kit? Itís deff on my radar. How
often you track it? Deff seems like a lot of bang for the buck. I would also be interested in how good the Wilwood rotors are vs say a 50$ cryo centric c6z rotor

I think the willwood and C6Z rotors are the same width, so maybe there is a difference in the offset.

MX6, the kit just got delivered. I'll finish off this year with my current setup and install the brakes this winter (along with square tires / rims, changing the front ride height and realignment). Just got a Sparco seat as well. I'm going to make my own mount, but that will go in before my next track event.

It depends which kit you have. Wilwood makes separate kits for use with c6 z06 rotors or wilwood rotors. They are different offsets.

This is the hat that comes with the kit: 170-8132. Edit, geesh, I keep going back and forth on the hat. I'll look at whats actually in the box tonight but I think its this one: 170-8919

Any idea of the stock rotor offset is? Probably easier for me to just find a trashed stock rotor locally and just try it.

WW also has c6z 2pc so you can compare hat dimensions on their site.

The WW C6Z 2-piece rotors have a hat offset of .23". The hats in my kit have .29" offset. Good suggestion Josh. Guess I'll order another set of rings and keep the safety wire / pliers in with my track tools!

Iím assuming the diff offset is to accommodate the 20mm padded race calipers. Vs the 17mm calipers that accept the stock c6z rotors? This kit has my attention, for obvious reasons I favor the race kit, but your stuck with fewer pad selection and the specific rotor. My Z is still a street car as well so maybe the 17mm caliper would work best?

Here's the poop.

1. The Aero6 CALIPER kit fits the stock rotor.

2. The Aero6 14.25" kit with 2pc hats and rotors and 17mm pads fit the supplied rotor.

3. The Aero6 14" Race kits with 2pc hats and rotors with 20mm pads fit the supplied rotor.

NONE of these will interchange with the other. We can go into great detail about the exact whys and hows but trust me: they don't.

*You can however purchase an alternate brand 2pc hat and rotor of EXACT OE SPEC in place of the one piece stock rotor and the CALIPER KIT will work with that.

*You can also purchase a Wilwood brand 2pc OE SPEC replacement rotor kit to use with the CALIPER KIT (which would be foolishly more expensive then just buying the complete kit) but you cannot use THAT 2pc with the complete kit in option 2.

NONE of the parts interchange with the RACE kit: hat, rotor, pad, caliper, bracket....

thanks for clearing that up. So letís say I wanted to
go with the race kit that uses the 20mm pads. My car is still a street car as well so could i use the polymatrix E pads on the same rotor on the street, then the bp40 pad on track? I saw in the Wilwood literature it says ď ok for streetĒ with the E compound. Are the diff Wilwood compounds compatible on same rotor?

Yes you could move from E to the H or 40s with minimal bedding between pad use. *I'd personally say that while "streetable" you'd likely find the E pads quite loud and abrasive for normal day use. The other option would be 17mm pads but use them with a pad wear plate to take up the lack of friction material ideally.

No reason you cannot use the 'race'; kit for the street but beware the hats and rotors may prove a bit loud cold due to the tee lug drives used for expansion and that they will have a serious impact on wheel choice. OE wheels may require a spacer so see the wheel fitment page to be certain.

Todd, thanks for the rotor / caliper interchange info.

MX, I went with the 17mm BP10 street pads. I like to make stuff so I'll knock out a bunch of pad spacers in various thicknesses.

The public release for the race kit said it comes with BP40. WW website for the kit says BP40 in the description and BP30 in the kit components info. It came with BP30 in the box.

Will the race calipers(for 20mm pads) fit under 18x10.5 speedline's without a spacer?

If you have the Aero6 Calipers that replace the stock calipers (Wilwood Part Number 140-12629) that use the stock rotor you can replace that rotor with the following rotor from Wilwood:
https://www.wilwood.com/BrakeKits/Br...tte&option=Z06 . 140-12496 is a drilled slotted rotor two piece rotor that will work with the Wilwood stock replacement calipers.

Before the Aero6 became available I had the W6A version of the caliper which replaced the stock caliper and worked with the stock rotor. I then replaced the stock rotors with this part number to get a full Wilwood 14 inch rotor and caliper setup. I ran the Wilwood rotors and had a couple of used stock rotors as spares if I happened to crack a Wilwood Rotor. I never did crack one. I had 13 track days on the first set of rings and decided to put some new ones on even though they weren't close to cracking. 160-12391 and 160-12392 are the replacement rotor rings for this set.

I used H pads on the track and Q pads on the street.

Todd provided all of the parts for me at great prices.

Bill
