Default Ask Tadge Poll: Ending 5/27/18

Hey folks -

We're going to skip a cycle with this one. Meaning: we'll run this poll for a week, as usual. Then when we've decided on the question, I'm going to sit on it for an extra week or two so Tadge can enjoy his Memorial Day weekend.

Vote for which of these 4 you'd like to have Tadge answer. The winner will be submitted 6/10/18.

The questions are posted in the replies below, with links to their respective threads.

Default C7 ZR1: Balanced Downforce

The original questions is here.

smurfmacaw asked:
I'd be interested in the changes to the ZR-1's front aero to balance the downforce from the massive wing riding in the back. I'm sure there is a preferred balance and significantly increasing the downforce in the back required some compensation in the front to prevent understeer at high speeds but it looks essentially the same as far as the splitter etc in the front (I've only seen pictures so they may be deceptive.)

Default Impact of leaving the ZR1 track cooling items installed on the street

The original question is here.

Poor-sha asked:
The C7 Z06 and the C7 ZR1 both come with secondary brake cooling ducts that the owner's manual states should be installed for track use and should be removed for street use. Additionally, the C7 ZR1 comes with exhaust cooling hardware that attaches to the tunnel plate and the owner's manual also recommends removing after the track event.

What are the risks associated with leaving this equipment in place during street operation?

Default C6 ZR1/Z07 Rear Brake Rotor Discontinued?

The original question is here.

racerns asked:
It seems that C6 ZR1/Z07 carbon ceramic rear brake rotor, GM OEM part # 22805790 and AC Delco part # 177-1121, is showing out of stock or discontinued throughout the country. Has this part truly been discontinued and if so what options do the owners of these cars that may only be 5 years old have for a compatible rotor? Are the C7 carbon ceramic rotors usable (fit) on the C6 carbon ceramic brake system? I believe the front rotor will, but the rear may be a different size.

Next part of this question has to do with the new C7 ZR1 brake pads. Are they compatible with the C6 carbon ceramic brake rotors?

Default ZR1 Front Quarter Panel Design Changes

The original question is here.

MMD asked:
I would like to hear Tadge's take on the new design feature of the wide-body style "front" quarter panels found on the ZR1. I have not read or heard anyone discuss this design deviation from the stock C7 wide body design that can be found on the Z06 and Grand Sport. Was this change a result of aeronautical engineering studies, computational fluid & thermal analysis, or was this change made just to mitigate issues related to stones and road debris being kicked up rearward outside toward the rear of the vehicle? I noticed the ZR1 did away with the wheel opening "spats" that where implemented since the 2017 model year. I would appreciate any insights learning about this little mentioned design change. Any possibilty this feature will be incorporated into the design of the 2020 model year Z06 and Grand Sport? It sure would aid in reducing road debris damage.
