Joshua, do you have pictures?

I do not have good pictures right now; let me get a few more of the rotor's from the side; especially the rears. I'll see if I can post it with the original Z51 rotor's pictures I have.

The stopping power must be felt of course

Generally that will actually decrease overall braking ability due to fixed brake proportioning. If you change your proportioning valve you will at least be able to have the same stopping distance as you would before, compared to having larger rear rotors.

The reason is that you can only apply as much brake as the wheel with least traction will support (with threshold braking, anyway). Your rears are unloaded during heavy braking anyway, so they have less ability to be "braked". If you can only give 30% before your rears lock up, compared to 40% before, then you're giving only 30% brake pressure to your fronts now, as well, compared to 40% before. So overall braking is reduced.

I wouldn't put such big brakes on my car unless I could tune the proportioning as well. Maybe the C6's anti-lock system is good enough that you can just stomp the brakes each time anyway and let it work its magic?

We have the technology; I believe the +1 is only an inch more in diameter. I'll have to break out my physics book and do some calculations; but I know when I put my finger on a record player at the inside it takes more force to slow it down; as opposed to when I'm on the outer edge.

How unbalenced it is remains to be seen; but I haven't had the brakes lock up on me yet and ABS has kicked in; so...

Stomping works

We've sold alot of these for the C5s and I also ran a set on my '00 convertible with no problems or the car feeling unbalanced while braking.

Plus 1's

Yeah, I'm just curious what bigger diameter rotors (than on the front) will look like on the rears.

You should see the rotors that I'll be putting on my Sierra next week. 16" Wilwoods up front with 6 piston calipers. The rotors are as big as the stock wheels!

Thanks - I didn't get time to photograph them today!!

The rears; being on a nineteen wheel look really good with the 14" rotor.

As I said, the stopping power is much better than stock. I have PFC-Z pads, Castrol SRF and the Eradispeed Rotors.

If you are going for LOOK only - the rotors might be a little pricey - but if you really want a stage 1 upgrade; these would do.

I'm targeting stainless lines and brakebleeders as next option.

Tom, what do you have left in stock for the rears? I have a non Z51 C6 and bought the fronts from you last weekend. Thanx.

tbyrne

We have the 2302021 - 2 piece rears in stock.

When mountain the rear 14" baer rotors do you need a longer brakeline? Or any speed sensor work?

By the way people are posting it doesn't sound like anything extra needs to be done, just swap out the oem rear rotor for the 14" baer rotor.

Just double checking.

thanks

tbyrne

You just need to swap the rotors and use the caliper spacer. Nothing else will be required.

davidfarmer

increasing the size of the rear rotor will change the lever arm, and throw the bias to the rear more. Going from a 12" to a 14" rear in an otherwise stock setup seems extreme.

Do you have any details on how to mount this spacer? There were none included in the package. It looks like the bolts which attach the spacer to the suspension (hex head) have only one washer. SHoudl there be two? If not, does this washer go on the head side or the nut side?

Thanks,

serendipity

Exactly. I wouldn't do it if it were my car.
