Other thoughts, alignment issue. May need more rear toe as some suspension geometries toe out under loading which can unsettle the rear. May go to one side if toe is uneven one side to the other. Also, more rear downforce might help (?big wing).

Thanks guys. I'll talk with optimum performance and see if they recommend less aggressive rear pad. And I'll check the alignment as well. Both sound like likely suspects.

Thanks for posting. Yours is really nicely done. Appears a little neater and better organized.

Lots of SoCal track guys on here. went to Buttonwillow c13 on much heavier aftermarket wheels and PS4S tires so I could get a closer comparison to my previous car M2, 991GTS and others I've taken stock first on a summer tire. Only did 2 sessions just to see. Didn't want to destroy the street tires Excited to go back with stock carbon wheels & Cup2 tires. Should shave 2-3 seconds easy
GT350R on heavier wheels & PS4S - 1:58:7
M2 Stock - 2:00:4.
M2 on KW Clubsports / Upgraded Pads / Re71R Tire - 1:57:2
991GTS - Manual - Stock - 1:58:4 came on Pzero
ZR1 Stock on Cup2 - 1:56:6 couldn't get confidence in that car
Viper TA - 1:53:7 - on Tractive Suspension/pads/ Stock Pzero Corsa
Tried overlaying Harry's data onto GoPro but it's off and Harry's timing messed up but should be the 1:58:7 lap

Looking forward to seeing your BW times on CF C2 setup. How were the 4S on track? I’ve got a similar setup where my N4S wheels have 305/325 4S tires for street and CF C2 for track.

I've put 3,400 miles on my C7 GrandSport and I have to admit this car might be the best value. The extreme handling and performance combined with exceptional poise and road manners has me hugely impressed.
It's 460hp Dry Sump V8 has probably been the biggest surprise for me. Coming from a GT350 I was less than excited about my new Corvette engine. GM proved me wrong. Though it doesn't have the sky high 8,250 rpm redline or perhaps the wild exhaust note of the GT350 it does have an incredible amount of torque to the point this motor almost feels like a twin turbo V8. Torque just everywhere and a wonderful understated exhaust note. There really doesn't feel much of a need to climb revs because at 2,000 rpm it's pulling like a freight train already. That's a really nice street manner because i'm not revving up to the moon anymore attracting law enforcement from every agency within 100 miles when I drive.
Ergnomics on the GrandSport is world class. Seating position, ride height, shifter placement, pedal placement all feel just right. Real sporty leather wrapped tight D bottom steering wheel (I understand the revised wheel wasn't offered until 16' or 17'). Touring seat itself is good for long commutes, roadtrips or a back roads spirited drive.
Touchscreen Media - fantastic. Bose surround sound is very entertaining and very user friendly.
GM rreally nailed it with this one, and it's ability to be luxury cruiser or race car at the press of a couple buttons is astonishing. This Corvette will likely be in my garage for many years and probably not replaced by anything but a C8 if that.

Agreed x 2. As a fellow C7 owner, I could not agree more. This is coming from having owned 3 M car's prior to this.

The Grand Sport is clearly a performance monster, as is the Z06. I have test driven the Z06 and have seen a Grand Sport in person but did not test drive it. Can't knock the performance, but the vette's just don't do it for me. Probably purely personal preference. Had the gt350r - soulful, exciting car even though it it outperformed by the Grand Sport and ZL1. I much preferred it. Have 991 GT3 and again, no comparison for me. The GT3 is simply a much more enjoyable car. Worth the price delta
