Bash updates and info
 

Points of interest so far:

Z51 4-5 seconds faster per lap at vir than prior z51 car. This is with c7 equipped with full datalogging equipment. Would not give exact time but it appears to be likely its 2:50 or 2:51

Shakedown test between grand sport oem goodyears vs c7 245/285's yielded 1 second per lap faster time. Test car was c6 z06. Vir. They have been amazed by the michelin tire

C7 now has adjustable rear caster, improved roll center and lower cog than c6

Mero says, the car feels lighter and is an absolute monster to drive....he assures everyone they'll be amazed.

MR suspension vastly improved. Faster processor, dual coil, far better ability to fine tune. The changes between modes for touring and track are substantial and only possible via this new generation system.

There was a lot discussed about E LSD and E power steering. If anyone wants details or has questions...ask.

Stiffness between the steering wheel and wheel bearing hub assembly improved 500% over c6. Communicates much better feel, improves response and reduces dynamic changes under load.

Nurburgring later THIS year

Someone started the vert while the interior guys were talking...good stuff!

Z51 brakes have 30% more swept area than prior z51's...even more swept area than c6z

New rotor design communicates very little thermal load from rotor to hub via new two piece design


More to come. If youre curious about anything, post it and I will try to get an answer.

:thumbs:

Have they talked about the LT1 yet?

Damnit, so still no word on the power output or weight?

For clarity, they used the OEM 275/325 Goodyears on a C6Z, then switched to the narrower 245/285 Pilot Super Sports on the C6Z, which was then 1 second a lap quicker with the narrower Super Sports around VIR?

Very nice. I know both tires very well (I have PSS on my DD) and I can't say I'm surprised. The PSS is a VERY good tire. I can't wait until they make them in larger sizes for 19/20 setups. I still have my PS2s to burn through first.

Thanks for getting info. Looking forward to more updates.

:lurk:

So the comparison had nothing to do with C6 vs C7, but just the differences in the tires.

I wonder if they also put a set of the new Michelins on the Z06, using the Z06 sizes and compared.

Are you glad you went now? :lol:

If Tadge didn't sell people on the C7, maybe Mero can. If you don't believe him well...

Wish they were more specific with the results but that sounds pretty darn quick. Pretty impressive. A bit behind the ZR1 but a hair quicker than a ZL1 using GMs test results.

FWIW, here are some other tests around VIR... those early C&D Lightning drivers (2006-07) must have been really awful or had some really bad weather those days. I take the results with a grain of salt but the data points are interesting.

C&D is also about 5 seconds a lap slower than GM test in both the ZL1 and ZR1...

GM VIR Testing -
ZR1 (Cups) - 2:45.63
ZL1 - 2:52.38

C&D VIR Lightning Lap
ZR1 (Cups) - 2:50.7 (02/2012)
ZR1 (PS2s) - 2:51.8 (02/2010)
Z06 (Z07 PS2s) - 2:53.5 (02/2011)
Camaro ZL1 - 2:57.5 (02/2013)
Z06 - 2:58.2 (08/2007)
GS - 2:58.3 (02/2010)
Z06 - 3:01.1 (11/2006)
Z51 LS3 - 3:01.20 (11/2008)
Camaro 1LE - 3:01.5 (02/2013)
Z51 LS2 - 3:03.6 (08/2007)
Z51 LS2 - 3:09.3 (11/2006)

Thanks very much for the info.

So what are the details on the e-LSD?

That is how I understood it when 'the test car was C6 Z06'.

I'm sure they tested the larger tires at some point, but they wouldn't dare share the results. It wouldn't make sense to upstage their new model with their outgoing car.

Thanks for the info

:lurk:

Thanks for the info, hope the prices are announced today.

Thanks for the updates :cheers:

Are the GM times with Jim Mero driving?

Jimmy

Keep the info coming, thanks!!

I'm pretty sure the ZL1 time was with Camaro engineer Aaron Link. He's the same guy who ran the official GM time on the ring with the ZL1.

IBTL now means :lurk: :rofl:
